How to turn bézier curves into surface

Please login with a confirmed email address before reporting spam

Hi,

is it possible to turn a bézier curve into a surface which can be extruded?

Thank you for your help.

Hi,

I am not 100% sure what you would like to generate. This is how I interpreted it:

1-) In a 3D geometry, right-click the Geometry 1 -node and add a workplane.
2-) Right-click Model 1>Geometry 1>Work Plane 1>Plane Geometry and add a Bézier-Polygon which can be piecewise linear, quadratic or cubic. (screenshot1.png). If you would like this curve to be closed (to be a surface), just change the type.
3-) Right-click Workplane 1 and choose Extrude -> You have a surface (solid, if you chose closed and solid in 2-)) in 3D.


If you are looking for topographical maps, please check model www.comsol.com/showroom/gallery/3807/

Hope that helps.
Regards,
Winfried

Ey,

when you are in the Bezier Polygon, in the settings window (the one in the middle of the screen), on the top, just under "general", it says "Type", and you can choose Solid, Open Curve, and Closed Curve.

That is what you want

Well, choose Solid ;-)

Thank you both. It's exactly the thing I was looking for. I just forgot to use a workplane.
