quick one

have a svg file and its line drawing now i want to make it a solid i extrude the lines but its not solid how do i go about it i use blender or freecad i have done it before but have mental block

Hi,

You might have chosen a more meaningful topic title than "quick one" which is rather cryptic...

In FreeCAD, an svg file import will create path objects in the Project tree. If your profile to extrude contains multiple paths you'll need to join them to create a face. One way is through the Draft Upgrade tool. Another is using Part's Shape Builder, selecting "face from edges".

If your profile is a single path object, this is unnecessary. Use Part Extrude with the "create solid" option ticked.

Please note that sometimes there are problems if the segments in the svg are not exactly joined together (CAD can be unforgiving!), in such cases you won't be able to create a face.

Also, to get a solid you need to have an outer perimeter that is not intersected by other segments. For example, a rectangle crossed by a diagonal line cannot extrude a solid.

Finally, the Part Extrude tool cannot deal with multiple closed profiles. For example, if a circle is within a rectangle. Then you need to extrude them separately, and apply a boolean cut to get a solid box with a hole in it.

You can load the SVG in Inkscape, then export it as DXF. Then you can import that DXF file in OpenSCAD to be extruded the way you want it as a 3d mesh. Export the resulting STL when you are happy.
