Re: sketch offset tool
There is no offset tool in Sketcher WB. There is a 2D offset in Part WB, you may have a look at it. It can offset sketches as well but I am not sure how the result behaves in FreeCAD 0.17 in terms of mixing Part Design/Body and Part WB stuff.

Thanks.

Re: sketch offset tool
it seems that Part_Offset2D doesn't work with negative offsetting (trying to shrink an outline)...chrisb wrote: ↑Sat Apr 22, 2017 3:01 pm There is no offset tool in Sketcher WB.

as in documentation:

enlarge is fine:
Code: Select all
import Part
circle = Part.Circle().toShape()
enlarged_circle = circle.makeOffset2D(0.5)
Part.show(circle)
Part.show(enlarged_circle)
Code: Select all
import Part
circle = Part.Circle().toShape()
shrinked_circle = circle.makeOffset2D(-0.3)
Part.show(circle)
Part.show(shrinked_circle)
Traceback (most recent call last):

Base.FreeCADError: FreeCAD exception thrown (makeOffset2D: result of offsetting is null!)
Re: sketch offset tool
Currently an Offset tool for sketches was already requested
https://www.freecadweb.org/tracker/view.php?id=3708
in comments it's said that it would be avaliable for the 0.19 version, but currently was not delivered so far!

Re: sketch offset tool
I am waiting for the sketch offset too, because I discovered a new application with FreeCad for me.Seems logical as 0.18 is hardly released and 0.19 just started its development cycle.
I started sewing a year ago and I am using FreeCad now as sewing pattern design software. The parametric sketcher is excelent for this purpose! Only TechDrawing workbench is needed beside sketcher.
In a last process step before exporting he pattern for printing a seam allowance has to be added to all edges of the pattern. This is in the simplest case a 2D offset of 1 to 2 cm on all borders. In more complex cases it would be useful to apply different offsets on different edges of the pattern.
I really love FreeCad. It has become an excellent tools with really useful features! Thanks to all developers.
