[OpenSCAD] Offset when using linear extrude

[Gadgetmind]

Hi,

I have vague memories of seeing someone trying to add offset/delat to
linear extrude and now have an idea that could really make use of this.

Did it go anywhere? Is it available in a build?

Thanks

Ian

It's not in any automatic build right now, the source and discussion
is at https://github.com/openscad/openscad/pull/2079

ciao,
Torsten.

Thanks. Is this now in mainline or on a branch?

I guess I need to start plugging away at building it from source.

It's in a forked repo. Github suggests the following commands
to get the code based on master which currently will create
a code conflict:

git checkout -b mrkmg-linear_extrude_offset master
git pull https://github.com/mrkmg/openscad.git linear_extrude_offset

As alternative, it would be possible to get that repo directly.

ciao,
Torsten.

If you have an affine description of the 2D polygon, you can always use a
sweep() to emulate any linear_extrude operation. As far as I know current
sweep implementations don't support 2D polygons with holes. But in this case
you still can sweep the primitives and do all the Boolean stuff in 3D.
