Create an offset path

graham_lock

Hi,

How should I go about creating a path offset by a given distance from another path?

Thank you.

@graham_lock . you have asked about every question that I had asked either on the forums, or directly to onshape. You cannot do a sketch offset.

I have been at this for 5 years in onshape (8 years automating solidworks for reference).

If you need to use sketch tools at all in featurescript, abandon what you are doing. You need to handle that stuff yourself. Sketch Relations in featurescript are dangerous as the results could be what ever the initialGuess is which is just a guess. To offset a curve, extrude it by 1mm then offset that face then extract the edge. I understand it is not a sketch but again, sketch tools in featurescript are basically impossible to use with any level of certainty. If you find a way, then that is great but not worth the time.

You can extrude a sheet body, opOffsetFace the face, get the resulting edge, and delete the sheet body.

Thank you but I’m trying to do this in Featurescript.

Thank you for your replies.

Extrude and offset should work well for what I’m trying to achieve.
