<h2><span class="mw-headline" id="OpenSCAD_language_and_file_format">OpenSCAD language and file format</span></h2>
|
||
<p>The OpenSCAD language allows the use of variables and loops. It allows you to specify submodules to reuse geometry and code. This high degree of flexibility makes parsing very complex. Currently the OpenSCAD module in FreeCAD can not handle the OpenSCAD language natively.
|
||
Instead, if OpenSCAD is installed, it can be used to convert the input to an output format named 'CSG'. It is a subset of the OpenSCAD Language and can be used as the input to OpenSCAD for further processing.
|
||
During conversion all parametric behavior is lost - all variable names are discarded, loops expanded and mathematical expressions evaluated.

<h2><span class="mw-headline" id="Limitations">Limitations</span></h2>
|
||
<p>OpenSCAD creates constructive solid geometry as well as importing mesh files and extruding 2d geometry (from dxf files). FreeCAD allows you to create CSG with primitives as well. The FreeCAD geometry kernel (OCCT) works using a boundary representation.
|
||
Therefore conversion from CSG to BREP should, in theory, be possible whereas conversion from BREP to CSG is, in general, not.
|
||
</p><p>OpenSCAD works internally on meshes. Some operations which are useful on meshes are not meaningful on a BREP model and can not be fully supported. Among these are convex hull, minkowski sum, glide and subdiv. Currently we run the OpenSCAD binary in order to perform hull and minkwoski operations and import the result. This means that the involved geometry will be triangulated. In OpenSCAD non-uniform scaling is often used, which does not impose any problems when using meshes. In our geometry kernel geometric primitives (lines, circular sections, etc) are converted to BSpline prior to performing such deformations. Those BSplines are known to cause trouble in later boolean operations. An automatic solution is not available at the moment. Please feel free to post to the forum if you encounter such problems. Often such problems can be solved be remodeling small parts. A deformation of a cylinder can substituted by an extrusion of an ellipses.

<h2><span class="mw-headline" id="Hints">Hints</span></h2>
|
||
<p>When importing DXF set the Draft precision to a sensible amount as this will affect the detection of connected edges.
|
||
</p><p>If FreeCAD crashes when importing CSG, it is strongly recommended that you enable 'automatically check model after boolean operation' in Menu → Edit → Preferences → Part Design → Model setting
