<p>Ritnings modulen tillåter dig att lägga ut ditt 3D arbete på papper. Det är, att lägga vyer av dina modeller i ett 2D fönster osh att sätta in det fönstret i en ritning, till exempel ett ark med en ram, en titel och din logotyp och slutligen skriva ut det arket. Ritningsmodulen är för närvarande under konstruktion och är mer eller mindre en teknologisk förhandstitt!

</p><p>I bilden så ser du huvudkoncepten av Ritningsmodulen. Dokumentet innehåller ett formobjekt (Schenkel) som vi vill göra en ritning av. Därför så är en "Sida" skapad. Sidan fås genom en mall, i detta fall "A3_Landskap" mallen. Mallen är ett SVG dokument som kan innehålla din vanliga sidram, din logotyp eller så den överensstämmer med dina presentationsstandarder.
|
|
</p><p>I denna sida så kan vi sätta in en eller fler vyer. Varje vy har en position på sidan (Egenskaper X,Y), en skalfaktor (Egenskap skala) och ytterligare egenskaper. Varje gång som sidan ,eller vyn, eller det refererade objektet ändras så regenereras sidan och visningen uppdateras.

<h3><span class="mw-headline" id="General_Dimensioning_and_Tolerancing">General Dimensioning and Tolerancing</span></h3>
|
|
<p>Drawing dimensions an tolerances are still under development but you can get some basic functionality with a bit of work.
|
|
</p><p>First you need to get the gdtsvg python module from here (WARNING: This could be broken at any time!):
|
|
</p><p><a rel="nofollow" class="external free" href="https://github.com/jcc242/FreeCAD">https://github.com/jcc242/FreeCAD</a>
|
|
</p><p>To get a feature control frame, try out the following:
|
|
</p>
|
|
<pre>import gdtsvg as g # Import the module, I like to give it an easy handle
|
|
ourFrame = g.ControlFrame("0","0", g.Perpendicularity(), ".5", g.Diameter(), g.ModifyingSymbols("M"), "A",
|
|
g.ModifyingSymbols("F"), "B", g.ModifyingSymbols("L"), "C", g.ModifyingSymbols("I")) </pre>
|
|
<p>Here is a good breakdown of the contents of a feature control frame: <a rel="nofollow" class="external free" href="http://www.cadblog.net/adding-geometric-tolerances.htm">http://www.cadblog.net/adding-geometric-tolerances.htm</a>
|
|
</p><p>The parameters to pass to control frame are:
|
|
</p>
|
|
<ol><li>X-coordinate in SVG-coordinate system (type string)</li>
|
|
<li>Y-coordinate in SVG-coordinate system (type string)</li>
|
|
<li>The desired geometric characteristic symbol (tuple, svg string as first, width of symbol as second, height of symbol as third)</li>
|
|
<li>The tolerance (type string)</li>
|
|
<li>(optional) The diameter symbol (tuple, svg string as first, width of symbol as second, height of symbol as third)</li>
|
|
<li>(optional) The condition modifying material (tuple, svg string as first, width of symbol as second, height of symbol as third)</li>
|
|
<li>(optional) The first datum (type string)</li>
|
|
<li>(optional) The first datum's modifying condition (tuple, svg string as first, width of symbol as second, height of symbol as third)</li>
|
|
<li>(optional) The second datum (type string)</li>
|
|
<li>(optional) The second datum's modifying condition (tuple, svg string as first, width of symbol as second, height of symbol as third)</li>
|
|
<li>(optional) The third datum (type string)</li>
|
|
<li>(optional) The third datum's material condition (tuple, svg string as first, width of symbol as second, height of symbol as third)</li></ol>
|
|
<p>The ControlFrame function returns a type containing (svg string, overall width of control frame, overall height of control frame)
|
|
</p><p>To get a dimension, try out the following:
|
|
</p>
|
|
<pre>import gdtsvg
|
|
ourDimension = linearDimension(point1, point2, textpoint, dimensiontext, linestyle=getStyle("visible"),
|
|
arrowstyle=getStyle("filled"), textstyle=getStyle("text") </pre>
|
|
<p>Inputs for linear dimension are:
|
|
</p>
|
|
<ol><li>point1, an (x,y) tuple with svg-coordinates, this is one of the points you would like to dimension between</li>
|
|
<li>point2, an (x,y) tuple with svg-coordinates, this is the second point you would like to dimension between</li>
