Segment Surface crash.

[Chris_G]

OK. Thanks.
But ... why would you call segment surface on this face ?

[Vincent B]

Im' trying to find out how to make fillet beetween faces.
Here trying to match isocurves to build blended curves.

Im tring to make fillet. And I would suggest a new feature with curve on surface:
- extend the side with red arrow to red dot.
- cut the blue side to blue dot.
Thanks a lot if you can.

After some test this weekend I'm sure, fillet is not the best friend of B Spline surface patches. we should really look for a method to get edges smoothed by yourself. Take the edge curve and find some good pole lists for both sides to get the filet smooth and tangent within an acceptable tollerance should be first step. Increase the precision without killing the performance to much can be a next step.

Blend Surface feature seems no working anymore?
check the hammax file (page4)

[Chris_G]

I'll look at that.
Thanks.

Hi,
I have added a new tool to the Workbench.
It is an interpolation curve with free-hand editing, and snapping ability.

Hi Chris, I'm working on the Draft Edit tool, and I just love the way you implemented markers in your Interpolation curve. @Triplus pointed me out your work long ago, but at that time I was still experimenting on other aspects of the tool.
I'm learning a lot looking at your code (I'm a really weak programmer) and i'd like to try to bring some of your improvements to the Draft Edit tool. Is there any license/copyright issue or other things i should consider?
thx a lot in advance!

Hi,
First important point : I am weak programmer too, so be warned you are not looking at high quality code !
The base of this tool comes from looo's work on pivy graphics
I think this is great tool to build a freehand editor.
The file 'graphics.py' from CurvesWB is a fork of it with a couple of tweaks.

My code is LGPL 2.1+ (like FreeCAD).
I have not checked about pivy's license exactly.

That's exactly what I was looking at
Thanks Chris, I'll give it a try during next month!
