Bug 0000142 Show_tangency_lines in drawing view closed?

[NormandC]

Hello,

Bug 0000142 was closed. But I have the latest r3907, and tangency lines still won't show in a drawing.

BTW I tried to create a view of an extrusion made of a closed Bspline, and I got this error:

App::Document::_RecomputeFeature(): Unknown exception in Feature "View" thrown

FYI here's how the part looks like.

Hi,

feel free to reopen the issue. The stuff with arcs is fixed because now we use directly the correct SVG entity therefore. About the showing of tangency I'm not completely sure what exactly you mean.

I can confirm the error message. I'll check where exactly the error is raised.

Cheers,
Werner

I closed the bug because Werner implemented one half of it and the other half was not clear to me!?

If its really bug reopen it, or better make a new feature request which state clear what you mean....

I handle properly now the error raised by OCC. There must be something wrong with the b-spline because the message says that degree and number of control points don't match. But as far as I can see the b-spline is valid otherwise OCC must have rejected to build it, actually.

Hello,

I'll open a new feature request, but I don't know how to make it clearer.

A tangency line is a line that separates two tangent surfaces. At least this is how it is called in Solid Edge and I think SolidWorks. A picture is worth a thousand words, so here's two

FYI, I found the topic where it was discussed originally: fillets in drawing views

Edit: feature request #243 created in Mantis, hope it is clear now.

Wow! That was fast!
