Re: Curves workbench
OK.
Please give a try with new v0.4.1

Re: Curves workbench
Still says 0.3.0 is installed, but the segment surface works as expected.

Re: Curves workbench
When creating a freehand b-spline why is snapping only allowed to other b-splines?
It would seem this is very limiting, since other geometry can't be used for reference.

Re: Curves workbench
Snapping should work for any geometry.
But the selection process during the BSpline editing is not working very well.

Re: Curves workbench
I agree the selection is a bit wonky.
I did think that the any vertex worked last I used it. But, today I noticed it was not. (And, I noted that my updates to the wiki on the use of the snap were updated to specifically say it would only snap to other b-splines.)
Also, is it possible to make a closed b-spline? Edit: still a question, but the JoinCurve does close the curve...
In the attached file the two b-splines loft ok, but because the ends just overlap (i.e. the XY coords of the start and end are the same) if fails geometry check. (At least I think that is the source of the error. It says Face1 has a selfintersect...but, I couldn't find Face1...)
Edit: scratch that. This file with the JoinCurves/loft fails geo. check.

Re: Curves workbench
Some nice videos with a few tips and ticks on surfacing (and few other things) in solidworks, but in general a lot of it can be useful to understand and do surfacing also in other programs...

Re: Curves workbench
Hi Chris,
I seem to be having the same problem drmacro had, I have V0.4.2 installed, regression?
The segmented surface problem that is.
TX Steve.

Re: Curves workbench
Hello,
Previous fix was not good.
Problem should be fixed now, I hope, with v0.4.3

Thanks very much for the quick attention, works now.
Curves workbench: problems with MapSketchToSurface
I thought I had a good idea to solve this help request by using MapSketchToSurface.
This is what I tried to get equidistant marks on a spiral surface:
- create a spiral in Part workbench
- extrude the spiral in Part workbench to the width of the roll
- create a sketch with a rectangle, change it to construction geometry
- - set length=Spiral.Shape.Length
- - set width=Extrude.Length
- create the marks on the rectangle, I have used equidistant circles
- use Curves > MapSketchToSurface to map the sketch to the face
However, since it is a spiral where the inner diameter is smaller than the outer, the holes should not lie all on a straight line.
I'm not sure if I made something wrong or if I expect the wrong thing or if Curves is doing it wrong.
It would probably work, if I split the spiral and the sketches in chunks of 360°, but I wanted to avoid the calculations.
