<h2><span class="mw-headline" id="Highlights">Highlights</span></h2>
|
|
<p>It's been 2 years since the previous 0.16 release, but the FreeCAD team didn't stay idle during that time. More than 6,800 revisions were added to FreeCAD's source code. For comparison, this is more than three times the work done between v0.16 and 0.15! Most existing workbenches benefited from improvements, and two completely new workbenches were added. New additional modules were also developed by the community. Some of the highlights:
|
|
</p><p><br />
|
|
The <b>PartDesign workbench</b> has been completely overhauled. A new Body container now holds a chain of features and lifts the requirement of mapping sketches to planar faces. New tools to create datum (reference) geometry such as points, axes and planes make PartDesign a lot more versatile.
|
|

|
|
<p>The new <a href="AddonManager.html" title="AddonManager">Addon manager</a> available from the Tools menu (which was previously available as the <a rel="nofollow" class="external text" href="https://github.com/FreeCAD/FreeCAD-addons">addons installer macro</a>) makes installing and updating add-on modules and macros much easier and standardized across Windows, Mac OS X and Linux.

<ul><li> Enhancement: <a href="Part_Revolve.html" title="Part Revolve">Part Revolve</a> tool now supports parametric link to revolution axis.</li></ul>
|
|
<ul><li> The new <a href="Part_Attachment.html" title="Part Attachment">Part Attachment</a> utility accessible from the <i>Part → Attachment…</i> menu can be used to attach most types of objects to other geometry parametrically.</li></ul>
|
|
<ul><li> The new <a href="Std_Part.html" title="Std Part">Part container</a> can be used to group most types of shapes and to move them as a unit. It also contains standard planes and axes to attach objects to. It will serve as basis for the future Assembly workbench by providing a way to move parts around. It is available in all workbenches from a toolbar along with <a href="Std_Group.html" title="Std Group">Group</a>.</li></ul>

<h2><span class="mw-headline" id="PartDesign_workbench">PartDesign workbench</span></h2>
|
|
<p>The PartDesign workbench received massive changes, the fruit of combined efforts from multiple developers over a period of 5 years.

<a href="https://www.freecadweb.org/wiki/index.php?title=File:PartDesign017-teaser-motor-core.png" class="image"><img alt="PartDesign017-teaser-motor-core.png" src="800px-PartDesign017-teaser-motor-core.png" width="800" height="425" srcset="/wiki/images/thumb/8/80/PartDesign017-teaser-motor-core.png/1200px-PartDesign017-teaser-motor-core.png 1.5x, /wiki/images/thumb/8/80/PartDesign017-teaser-motor-core.png/1600px-PartDesign017-teaser-motor-core.png 2x" /></a>
|

</p>
|
|
<ul><li> The new <a href="PartDesign_Body.html" title="PartDesign Body">Body</a> container holds a chain of of PartDesign features making up a single contiguous solid. It also contains standard planes and axes to attach objects to. Thanks to the Body container, it is no longer necessary to map sketches to faces when adding features. This requirement was a major limitation of the old PartDesign, that could cause many models to break upon parameter changes. So, it is now recommended to avoid mapping sketches to faces whenever possible.</li></ul>
|
|
<ul><li> New additive and subtractive features: <a href="PartDesign_CompPrimitiveAdditive.html" title="PartDesign CompPrimitiveAdditive">Primitives</a>, <a href="PartDesign_AdditiveLoft.html" title="PartDesign AdditiveLoft">Loft</a>, <a href="PartDesign_AdditivePipe.html" title="PartDesign AdditivePipe">Sweep</a>, <a href="PartDesign_Thickness.html" title="PartDesign Thickness">Thickness</a>.</li></ul>
|
|
<ul><li> New datum features, which are <a href="PartDesign_Plane.html" title="PartDesign Plane">planes</a>, <a href="PartDesign_Line.html" title="PartDesign Line">lines</a> and <a href="PartDesign_Point.html" title="PartDesign Point">points</a> useful for placing sketches, alignment, and serving as axes of revolution.</li></ul>
|
|
<ul><li> New automatic workbench switching between PartDesign and Sketcher. When creating a new sketch from within the PartDesign workbench, once the sketch attachment is set, the UI automatically switches to the Sketcher workbench and its tools in editing mode. When the sketch is closed, the UI switches back to the PartDesign workbench, and restores the view to its previous state. Thus the Sketcher tools were removed from the PartDesign toolbars to liberate space for the new PartDesign features.</li></ul>

<h2><span class="mw-headline" id="Path_Workbench">Path Workbench</span></h2>
|
|
<p>The Path workbench has been massively overhauled in version 0.17. The overhaul saw the removal of all older HeeksCNC code and replacement of the libarea python wrapper with the new Path-Area module. As a result operations have gotten much more powerful, faster, with a simplified code base.
|
|
</p>
|
|
<ul><li> Support for 2.5D operations is complete including <a href="Path_Contour.html" title="Path Contour">contour</a>, <a href="Path_MillFace.html" title="Path MillFace">face-milling</a>, <a href="Path_Pocket_Shape.html" title="Path Pocket Shape">pocketing</a>, <a href="Path_ProfileFace.html" title="Path ProfileFace">profiling</a>, and <a href="Path_Drilling.html" title="Path Drilling">drilling</a></li></ul>
|
|
<ul><li> Limited support for <a href="Path_Pocket_3D.html" title="Path Pocket 3D">3D pocketing</a> operations.</li></ul>
|
|
<ul><li> Path can use <a href="Arch_Panel.html" title="Arch Panel">Arch Panel</a> as base object to group multiple parts together for 2D cutting.</li></ul>
|
|
<ul><li> Introduction of <a href="Path_Job.html" title="Path Job">Path Job</a>. The job is now a central object of the path workflow. It organizes and coordinates multiple operations, tools, stock material, part orientation and alignment. A customized Job can be saved as a 'Job Template' and re-used to streamline the setup of future jobs. Job SetupSheets provide a mechanism to automate the configuration of depth and speed settings.</li></ul>
|
|
<ul><li> All operations have a consistent task panel organization</li></ul>
|
|
<ul><li> New or improved <a href="Path_Post.html" title="Path Post">post-processors</a> for LinuxCNC, Smoothieboard, GRBL, Phillips, OpenSBP (shopbot), Roland Modela, Centroid, Fablin, and Dynapath. Most post-processors support arguments.</li></ul>
|
|
<ul><li> Improved <a href="Path_ToolLibraryEdit.html" title="Path ToolLibraryEdit">tool library</a> and editor.</li></ul>
|
|
<ul><li> <a href="Path_Inspect.html" title="Path Inspect">Path Inspect</a> tool allows highlighting individual commands to visualize path and explore gcode.</li></ul>
|
|
<ul><li> <a href="Path_Simulator.html" title="Path Simulator">Path Simulator</a> tool does 3D simulated cutting to visualize Path execution</li></ul>
|
|
<ul><li> Dress-up operations can be used to refine core operations and add additional complexity. Dressups exist for <a href="Path_DressupDogbone.html" title="Path DressupDogbone">'dogbone'</a> corners, <a href="Path_DressupTag.html" title="Path DressupTag">holding tags</a>, <a href="Path_DressupRampEntry.html" title="Path DressupRampEntry">ramp entry</a>, and <a href="Path_DressupDragKnife.html" title="Path DressupDragKnife">dragknife</a> 'corner actions'</li></ul>
|
|
<h2><span class="mw-headline" id="Sketcher_Workbench">Sketcher Workbench</span></h2>
|
|
<ul><li> Sketches can now be attached in a wide variety of ways, not only to flat faces as it used to be. Of particular importance is attachment perpendicular to edges, useful for making profiles for <a href="Part_Sweep.html" title="Part Sweep">sweeping</a>.</li></ul>
|
|
<ul><li> External geometry links are no longer limited to only the object the sketch is mapped to. Geometry from other sketches is supported. External geometry links can be created within a Part container, or a Body container, or even a whole project if Part and Body containers are not used.</li></ul>
|
|
<ul><li> Visibility automation: now, when you start editing a sketch, objects depending on it are automatically hidden to unclutter the view, and objects used for external geometry links are automatically shown; old visibilities are restored as you close the sketch.</li></ul>
|
|
<ul><li> New constraint continuous creation mode: constraint tools are now active even without any element selected. Press a constraint, then select objects to apply the constraint to.</li></ul>
|
|
<ul><li> New arc of hyperbola and arc of parabola creation tools.</li></ul>
|
|
<ul><li> New Extend edge editing tool.</li></ul>
|
|
<ul><li> New B-spline creation tool, with many ways to control curves (degree, knot multiplicity, control point weight) and display information (control polygon, curvature comb, knot multiplicity indicator).</li></ul>
|
|
<p><a href="https://www.freecadweb.org/wiki/index.php?title=File:FC017_Sketcher_B-spline_01.png" class="image"><img alt="FC017 Sketcher B-spline 01.png" src="FC017_Sketcher_B-spline_01.png" width="590" height="422" /></a>
|
|
</p>
|
|
<ul><li> New <b>Carbon Copy</b> tool to copy geometry from another sketch.</li></ul>
|
|
<ul><li> Virtual space switches all constraints to a different "virtual space", in effect hiding them from view.</li></ul>
|
|
<ul><li> Constraints List box includes ability to hide internal alignment, as well as individual hiding of constraints with a checkbox.</li></ul>
|
|
<ul><li> The Block constraint removes all degrees of freedom for a geometry element in place with the use of a single constraint. It should be particularly useful to work with B-Splines, which are cumbersome to constrain.</li></ul>
|
|
<ul><li> New Regular polygon with user defined number of sides.</li></ul>
|
|
<ul><li> Alternative sketch solvers available through <i>Show Advanced Solver Control in Task Bar</i> in Sketcher preferences.</li></ul>
|
|
<ul><li> Geometry style based rendering order allows reordering between normal, construction and external geometry. Useful when these type of geometry overlap.</li></ul>
|
|
<ul><li> The solver now automatically substitutes a combination of coincident constraint + tangent constraint with a point-on-point tangent constraint, as the former is an improper use that induces tolerance error that can cause further problems in the model. The user is advised of the substitution by a dialog which can be disabled in Sketcher preferences by unchecking "Notify automatic constraint substitutions".</li></ul>
|
|
<ul><li> New tick box in edit mode task view "Avoid redundant auto constraints"</li></ul>
|
|
<ul><li> Horizontal and Vertical constraints can be used to align selected points.</li></ul>
|
|
<h2><span class="mw-headline" id="Spreadsheet_Workbench">Spreadsheet Workbench</span></h2>

<h2><span class="mw-headline" id="TechDraw_Workbench">TechDraw Workbench</span></h2>
|
|
<p><a href="TechDraw_Module.html" title="TechDraw Module">TechDraw</a> is a new workbench for creating technical drawings that aims to replace the aging Drawing workbench. FreeCAD v0.17 is still shipped with the Drawing workbench so you can still open and edit your files containing Drawing pages, but Drawing will be phased out in a future release. Some of the exciting new stuff that TechDraw brings:
|
|
</p>
|
|
<ul><li> Most tools from the Drawing workbench have a TechDraw counterpart.</li>
|
|
<li> Easier view creation and manipulation. Views can be grabbed by their border with the mouse and dragged on the page. Orthogonal views alignment can be locked.</li>
|
|
<li> Better line type management (hard, smooth, iso, seam). Better hidden line removal thanks to an updated <a href="/wiki/Glossary#OCC" title="Glossary">OCC</a> library.</li>
|
|
<li> Section view, detail view creation.</li>
|
|
<li> Better template management.</li>
|
|
<li> Dimensioning is now supported, through multiple dimensioning tools: horizontal, vertical, length, radial, diameter, angular.</li>
|
