3D polylines with featurescript?

albjerre

Hi. I want to make featurescript where I can make a 3D polyline with featurescript. When the polyline is created I also want to be able to make sketch fillets on the corners afterwards. How should I approach this?

One of the featurescript samples is "Featurescript 3D spline". Can I use this as a basis?

Making a number of 3D line segments is relatively simple -- and yes, the 3D spline can be used as an example.  Filleting corners would not be (you'd have to create the right sketch plane, "use" the lines and fillet the corner and then trim them).  Here's a script that creates the lines and arcs given 3D points and a radius: https://cad.onshape.com/documents/453c51c8807f37082c1247f3/v/9dac4678249816079b401245/e/8b9b8d950f11fd8c3015a878
Currently, to turn it into one wire body (as opposed to the mixture of 3D lines and sketch arcs that it is currently), you'd have to convert it into something opCreateBSplineCurve could take.  In the near future, you'll be able to combine the results into one curve more easily.

Thanks @ilya_baran
For some reason, I did not see your reply before know. Yes, that custom feature was exactly what I needed.

I’d like to know how making a number of 3d line segment. Or if there is a custom future for polylines 3d. Thank you in advance.
