|

<p>Det lättaste sättet är att gå till <a href="https://www.freecadweb.org/wiki/index.php?title=Download/sv" title="Download/sv">Nedladdningssidan</a>, där du hittar flera installationsfärdiga paket för Windows, Linux och Mac OSX system. Om du är på ett debian (>= squeeze) eller ubuntu (>= 10.4) system, så är FreeCAD redan inkluderat i standardförråden och du kan helt enkelt installera den med pakethanteraren. Notera att sådana paket endast släpps då och då, när utvecklarna finner det passande, och de följer för tillfället inget fast släppschema.

<h3><span class="mw-headline" id="What_are_the_prerequisites_for_running_FreeCAD.3F">What are the prerequisites for running FreeCAD?</span></h3>
|
|
<p>In contrast to most 3D CAD software, FreeCAD can run smoothly on the most modest computers - it's been known to run on Pentium IV and Intel Core2 Solo CPUs. If your computer is running a current operating system, chances are FreeCAD will run. The only prerequisite is that your graphics card or chipset must support <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/OpenGL">OpenGL</a>, preferably no older than v2.0. In case of problems, refer to the <a href="/wiki/FAQ#Troubleshooting" title="FAQ">Troubleshooting</a> section of this FAQ.

<p>FreeCADs källkod finns alltid tillgänglig i projektets källkodsförråd. Genom att kompilera FreeCAD själv så kan du få de allra senaste funktionerna som utvecklas, men det kräver an viss datorkunskap, fastän proceduren är ganska enkel. Åtkomst till förklaras på <a rel="nofollow" class="external text" href="http://sourceforge.net/projects/free-cad/develop">här</a>, och vi har detaljerade kompileringsinstruktioner på <a href="https://www.freecadweb.org/wiki/index.php?title=CompileOnWindows/sv" title="CompileOnWindows/sv">Windows</a>, <a href="https://www.freecadweb.org/wiki/index.php?title=CompileOnUnix/sv" title="CompileOnUnix/sv">Linux</a> och <a href="https://www.freecadweb.org/wiki/index.php?title=CompileOnMac/sv" title="CompileOnMac/sv">Mac OSX</a>.

<h3><span class="mw-headline" id="FreeCAD_tells_me_some_module_or_application_is_missing">FreeCAD tells me some module or application is missing</span></h3>
|
|
<p>FreeCAD depends on a lot of things to offer all its functionality. All the main required components are usually bundled within your FreeCAD installation or provided by your package manager, so normally you have nothing to worry about. If you installed FreeCAD from unofficial sources, however, or compiled FreeCAD yourself, some piece might be missing, which is not critical to FreeCAD itself, but might cause some functionality to be unavailable. Some specific file formats such as Collada or DWG also require extra components, which cannot be bundled into FreeCAD, and must be installed by yourself separately.
|
|
</p><p>All those components and the appropriate way to install them are listed on the <a href="Extra_python_modules.html" title="Extra python modules">Extra python modules</a> page.

<h3><span class="mw-headline" id="FreeCAD_Startar_inte_alls">FreeCAD Startar inte alls</span></h3>
|
|
<p>Det kan finnas många skäl till det, det troligaste är att något bibliotek saknas. Försök att starta FreeCAD från en terminal, skriv <i>freecad</i>, se om några fel kommer fram. Läs resten av denna FAQ eftersom det kan ge dig mer ledtrådar till att hitta problemets orsak. Om ingenting hjälper, berätta om det på <a rel="nofollow" class="external text" href="http://forum.freecadweb.org/">forumet</a>, det finns säkert någon som kan hjälpa till...
|
|
</p><p>On some older Windows XP systems you may get an error message like this: <i>The application can't start, because the side-by-side configuration is wrong. The reinstallation of the application may solve the problem.</i> The reason for this problem is that on your system either the CRT runtime libraries are missing or the version installed is too old because FreeCAD was linked against a newer version. In this case you have to install the Microsoft Visual C++ Redistributable Package which you'll find at Microsoft. See also the corresponding <a rel="nofollow" class="external text" href="http://forum.freecadweb.org/viewtopic.php?f=3&t=1298&p=9961">forum message</a>.

|
|
<p>Vissa delar av FreeCAD beror på en extern Pythonmodul kallad Pivy. On Windows så är pivy inkluderat i FreeCAD installationen. På Debian/Ubuntu system, så är python-pivy paketet en del av standard mjukvaruförråden. På andra system, så kanske du för tillfället får kompilera pivy själv. Notera att fastän en del verktyg inte finns tillgängliga om inte pivy är installerat, så fungerar resten av FreeCAD normalt.

|
|
<p>FreeCAD beror på OpenGL för att visa 3D innehåll, och kräver därför en fungerande OpenGL miljö. På en del system så är OpenGL som standard inte aktiverat, och du kanske behöver installera eller uppgradera dina grafikdrivrutiner. Detta problem uppstår oftast på Linuxsystem eller på virtuella system. Om du är på ett linux-baserat system, försök med följande steg:
|
|
</p>
|
|
<ul><li> verifiera att din dator har ett 3D-kapabelt grafikkort</li>
|
|
<li> skriv <b>glxinfo</b> i ett terminalfönster, och kontrollera i resultatet att Direct Rendering är inställt på "yes", och att OpenGL leverantören/rendereraren/versionen matchar ditt grafikkort.</li>
|
|
<li> installera annan OpenGl-baserad mjukvara (till exempel blender) och kontrollera om det fungerar och visas korrekt</li></ul>
|
|
<h3><span class="mw-headline" id="FreeCAD_kraschar_vid_uppstart">FreeCAD kraschar vid uppstart</span></h3>
|
|
<p>En krasch kan peka på en mer allvarlig bugg, eller på något problem i din konfiguration. De flesta uppstartskrascher uppstår på grund av en av följande två orsaker:
|
|
</p>
|
|
<h4><span class="mw-headline" id="Drivrutiner_f.C3.B6r_OpenGL_.C3.A4r_inte_inslallerade.2C_eller_fungerar_inte_korrekt">Drivrutiner för OpenGL är inte inslallerade, eller fungerar inte korrekt</span></h4>
|
|
<p>Detta är en mycket vanlig problemorsak. Symptomen är att FreeCAD kraschar vid uppstart, eller närhelst du öppnar en 3D vy (till exempel genom att öppna ett nytt dokument). Försök att ta reda på vilket grafikchip du har, ta sedan reda på om det stöder OpenGL (vilket de flesta senare chip gör), leta sedan reda på korrekt drivrutin och installera den. Ett bra sätt att dubbelkontrollera om opengl finns är att försöka köra en annan opengl applikation som <a rel="nofollow" class="external text" href="http://www.blender.org">blender</a>.
|
|
</p><p>And as a general tip to get some more information about crashes with FreeCAD you can start it with the program parameter --write-log. This will create the file FreeCAD.log in $HOME/.FreeCAD on Linux and Mac OS X or %APPDATA\FreeCAD% on Windows systems.
|
|
</p><p>In some rare cases you may have a graphic driver installed that doesn't fit to your graphic card. We had a case where the user's laptop had an Intel on-board graphic but some ATI drivers were installed. <a rel="nofollow" class="external autonumber" href="http://forum.freecadweb.org/viewtopic.php?f=13&t=5160&start=10#p41042">[1]</a>
|
|
After removing the files and re-installing the correct driver FreeCAD started to work.
|
|
</p>
|
|
<h4><span class="mw-headline" id="En_del_bibliotek.2C_som_FreeCAD_beh.C3.B6ver.2C_finns_inte_p.C3.A5_ditt_system.2C_eller_hittades_inte_av_FreeCAD">En del bibliotek, som FreeCAD behöver, finns inte på ditt system, eller hittades inte av FreeCAD</span></h4>
|
|
<p>Det kan finnas två grenar på detta problem: antingen saknas något bibliotek, och FreeCAD vägrar att starta, eller så finns biblioteket, men versionen på den är äldre än vad FreeCAD förväntar sig, så en krasch uppstår när FreeCAD försöker att använda en funktion som saknas i det biblioteket. Et vanligt exempel är när du har Qt3 och Qt4 installerat på ditt system, FreeCAD kanske upptäcker Qt4 men om din Qt installation inte är korrekt konfigurerad, så kanske en del bitar av Qt3 fortfarande används, vilket kan provocera fram en krasch.
|
|
</p><p>Läs igenom <a href="https://www.freecadweb.org/wiki/index.php?title=Installing/sv" title="Installing/sv">Installationsproceduren</a>, försäkra dig om att du har installerat alla nödvändiga bibliotek (på de flesta linuxsystem så görs detta automatiskt), och kontrollera det minsta versionsnumret för varje komponent.
|
|
</p><p>Om allt verkar korrekt, beskriv problemet på <a rel="nofollow" class="external text" href="http://forum.freecadweb.org/">forumet</a> eller <a href="https://www.freecadweb.org/wiki/index.php?title=Tracker/sv" title="Tracker/sv">posta en buggrapport</a>. Om du är på ett linuxsystem, så är det lätt att göra en debug backtrace, vilket ger mycket användbar information om kraschen till utvecklarna:
|
|
</p>
|
|
<ul><li> skriv i en terminal: <i>gdb freecad</i> (förutsatt att paketet gdb är installerat)</li>
|
|
<li> inuti gdb, skriv <i>run</i></li>
|
|
<li> efter kraschen, skriv <i>bt</i> för att få backtracen, som du kan inkludera i din buggrapport.</li></ul>

<h3><span class="mw-headline" id="FreeCAD_freezes_after_startup">FreeCAD freezes after startup</span></h3>
|
|
<p>When starting FreeCAD the GUI appears almost immediately but the GUI is frozen and the cpu is about 99%. This can happen on the KDE desktop when using the Oxygen theme. That's a bug in the Oxygen theme and choosing another theme should fix this issue.
|
|
</p>

<h3><span class="mw-headline" id="FreeCAD_kraschar_n.C3.A4r_ett_nytt_dokument_skapas_eller_n.C3.A4r_en_fil_.C3.B6ppnas">FreeCAD kraschar när ett nytt dokument skapas eller när en fil öppnas</span></h3>
|
|
<p>Om FreeCAD kraschar när den skapar en ny 3D vy, försök att starta FreeCAD från en terminal. om ett felmeddelande kommer fram när kraschen uppstår, som nämner "Assertion Failed" och ett komponentnamn som börjar med "So" (SoBase, SoFieldContainer, etc...), så är det mycket sannolikt, speciellt om du är på linux, att FreeCAD försöker att använda två olika versioner av coin biblioteket, vilket orsakar kraschen.
|
|
För att verifiera att detta verkligen är problemet, försök med följande:
|
|
</p>
|
|
<ul><li> Hitta FreeCADs körfil (vanligtvis i /usr/lib/FreeCAD/bin)</li>
|
|
<li> Kör komandot 'ldd FreeCAD' från en terminal</li>
|
|
<li> Notera vilken version av libCoin.so biblioteket FreeCAD använder (till exempel libCoin.so.60)</li>
|
|
<li> Hitta libSoQt.so biblioteket (vanligtvis i /usr/lib)</li>
|
|
<li> Kör 'ldd libSoQt.so' och kontrollera om den länkar till samma coin version som FreeCAD</li></ul>
|

<p>Om det finns någon skillnad, så måste antingen FreeCAD eller SoQt kompileras om (det är bättre att kompilera om den som använder den äldsta Coin versionen). Det normala beteendet är att försöka kontakta de personer som ansvarar för paketeringen av antingen SoQt eller FreeCAD och snällt be dem att överväga en omkompilering.
|
|
Om du vill göra omkompileringen själv, och det inte är möjligt att kompilera om SoQt därför att det förstör andra applikationer på ditt system, så kan du tvinga FreeCAD att kompileras med önskad Coin version med ./configure --with-coin=DIR. Men du måste försäkra dig om att korrekt devel paket för denna Coin version är installerad.

<p>A segmentation fault happens at vbo_save_playback_vertex_list(). This means that the implementation of VBO of the graphic driver is bad. In order to avoid to cache OpenGL calls you can try to set the environment variable IV_SEPARATOR_MAX_CACHES=0 and restart FreeCAD.

<p>The Mac platform is less easy to support than Windows or Linux, since none of the core developers owns one. The OSX packages are compiled by volunteering FreeCAD users, and they might sometimes not work correctly on your machine, depending on your system. Your best chance is probably to head to the forums, look for Mac OSX-related threads, and discuss your problem there or see if someone else encountered a solution.

<p>This can also happen if you had an older version of FreeCAD installed, and you upgraded to a newer version. In that process, the configuration files of FreeCAD might have been corrupted for some reason, and now FreeCAD cannot read them anymore, and fails to start. The solution is simply to delete these configuration files, so FreeCAD will recreate them on first run.

|
|
<ul><li> On Windows: Open the file explorer, and write "%APPDATA%\FreeCAD" as the file path. Once there, delete the files user.cfg and system.cfg</li>

|
|
<p>Teorin är simpel: Linjer (eller trådar), som extruderas, formar ytor. Ytor som extruderas, formar solider.
|
|
Om du extruderar 'någonting' och resultatet inte är en solid, då var 'någonting' inte en yta. Om du har linjer, och du vill extrudera en solid från dem, så måste du först välja linjer som formar en sluten omkrets (välj flera objekt genom att trycka på <span style="background: #DDDDDD; border: 1px solid #888888; padding: 0px 5px 1px 5px;">CTRL</span>), förena dem till en tråd (Uppgraderingsverktyget), gör sedan en yta från den tråden (Uppgraderingsverktyget igen). Om allt gick bra så kan du nu extrudera den till en solid.
|
|
</p><p>Det kan finnas många småsaker som gör att du får fel resultat. Det bästa sättet är att kontrollera vad som finns inuti det som du extruderar. Objektinnehåll kan utforskas lätt med python. Om vi till exempelantar att du har ett objekt som kallas för "Wire", så kan du skriva följande i python konsollen:
|
|
</p>
|
|
<div class="mw-highlight mw-content-ltr" dir="ltr"><pre>obj = FreeCAD.ActiveDocument.Wire
|
|
shp = obj.Shape
|
|
print shp.Faces
|
|
print shp.Wires
|
|
if shp.Wires:
|
|
for w in shp.Wires:
|
|
print w.isClosed()</pre></div>
|
|
<p>Ovanstående kod hämtar formen från ett objekt, och visar de ytor och trådar som ditt objekt har (om det har några), och om det finns trådar, skriver om dessa trådar är slutna (bildar en omkrets). Om du inte har någon yta, så kommer du inte att få någon solid. Om det inte finns någon sluten tråd, så kommer du inte att få någon yta. Om du är intresserad, så finns det mer info om vad du kan kontrollera med python på <a href="https://www.freecadweb.org/wiki/index.php?title=Topological_data_scripting/sv" title="Topological data scripting/sv">skriptsidan</a>. Om du inte kan förena flera linjer till en tråd, så är den troligaste orsaken att deras ändpunkter inte möts, det finns ett litet gap mellan (några av) dem. Min erfarenhat säger mig att då är det snabbaste sättet att åtgärda detta är att rita om linjerna ovanpå de gamla...

<p>The <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Open_CASCADE_Technology">Open CASCADE</a> geometric modeling kernel used in FreeCAD for Part geometry, although probably the best open-source geometry kernel available, has its flaws and limitations. Indeed the boolean operations (fusion, subtraction, intersection) are not its best features, and often give strange results. This is a current limitation we have no way to solve at once, so your best path is to try obtaining the desired result by modeling another way. For example, problems with primitives such as cylinder can often be solved by using an extruded circle instead. Coplanar surfaces between parts can cause trouble, as well as surface tangency. As a general rule, if a shape doesn't work, try remodeling it a different way. In 99% of the cases at the end you will manage to obtain the result you want.

|
|
<p>Don't use Crtl + A (Select All) to export everything from the hierarchy tree. If the model is of one single item, try selecting only the newest item (usually the last one) in the hierarchy tree.
|
|
</p><p>As we create a model in the Part Design workbench, each feature takes the shape of the last one and adds or removes something, creating linear dependencies from feature to feature as the model is created. Hence a "Cut" feature is not only the cut hole itself, but the whole part with the cut. This is why the user usually should only have the newest item (feature) in the model tree visible, because otherwise the phases of the model overlay each other, and holes are filled in by the earlier model features.
|
|
</p><p>To toggle visibility of an object on or off, select it in the hierarchy tree and press the Spacebar. Usually everything but the last item in the hierarchy tree should be greyed out and therefore not visible in the 3D view.

|
<div class="mw-translate-fuzzy">
|
|
<p>Det finns många olika sätt att hjälpa till, även om du inte kan programmera. Här ä rnågra saker som du kan göra:
|
|
</p>
|
|
<ul><li> Ge feedback till FreeCADs utvecklare: Det är alltid värdefullt att få reda på vad folk tycker, vad de tyckte var bra, vad de saknar, etc. Skriv en notering på <a rel="nofollow" class="external text" href="http://forum.freecadweb.org/">forumet</a> och ge oss din åsikt!</li>
|
|
<li> Hjälp med att skriva dokumentation: Den dokumentation som vi har här på denna plats är ibland mycket begränsad. Om du hittar något som har dålig dokumentering, lägg till din kunskap där!</li>
|
|
<li> Hjälp andra nybörjare: Uppehåll dig på forumen, och hjälp nya människor med att svara på grundläggande frågor, som hur jag installerar, hur lägger jag till en kub, etc...</li>
|
|
<li> Översätt dokumentationen: Att översätta denna wiki är lätt, du behöver bara lägga till en /språkkod sida för att skapa en översättning. För att till exempel översätta <a href="Part_Module.html" title="Part Module">Part_Module</a> sidan (dess url slutar med index.php?title=Part_Module) till danska, så behöver du bara lägga till /sv till url:en, vilket kommer att skapa en <a href="https://www.freecadweb.org/wiki/index.php?title=Part_Module/sv" title="Part Module/sv">Part_Module/sv</a> sida.</li>
|
|
<li> <a href="https://www.freecadweb.org/wiki/index.php?title=Localisation/sv" title="Localisation/sv">Översätt FreeCAD</a> till ditt eget språk</li>
|
|
<li> Skriv övningar, eller spela in videoövningar: Övningar är ettt mycket lätt sätt för nybörjare att lära sig en ny mjukvara. Om du har gjort några fina saker, varför inte visa andra människor hur man gör det?</li>
|
|
<li> Bidra med tillgångar och exempel: vi saknar fortfarande bra exempelfiler i FreeCAD. Om du har skapat något bra, dela med dig till oss!</li>
|
|
<li> <a href="https://www.freecadweb.org/wiki/index.php?title=Tracker/sv" title="Tracker/sv">Posta buggar</a>: Det är mycket viktigt att få alla möjliga buggar fixade. Om du hittar en, rapportera den så tydligt som möjligt, så att vi kan förstå exakt vad som händer.</li>
|
|
<li> Försök att skriva lite python kod: Du har aldrig programmerat förut men vill försöka? Python är lätt. Läs vår <a href="https://www.freecadweb.org/wiki/index.php?title=Introduction_to_Python/sv" title="Introduction to Python/sv">Python introduktion</a>... men var försiktig, du kanske får blodad tand!</li></ul>

<p>No. FreeCAD is totally free to use, to download, to redistribute, or to modify. It is <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Open_source">open-source software</a>, published under the terms of 2 free software licenses (<a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Gpl">GPL</a> and <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/GNU_Lesser_General_Public_License">LGPL</a>), which guarantee you those freedoms, and, even more important, guarantee you that these freedoms will never be taken from you.

<p>Sure. All the artwork (icons, banners, etc...) of FreeCAD is LGPL, same as the FreeCAD code. Help yourself on the <a href="Artwork.html" title="Artwork">Artwork</a> page. The website is a standard mediawiki site, all graphic elements can freely be reused, and if you are curious about how to tweak the mediawiki software like we did, look for the special Common css and js pages.
