Graphic to a cylindric surface ?

Postby mclien1 » Sun Mar 15, 2020 7:53 pm

Here is what I need to do.
I have a 2D Graphic, which I need to get on a cylinder. Kind of the reverse sheetmetal development.
Is there a way to do it? (similar to the circular text macro)

Background is: I have piece of tube into which I want to have a graphic cut into with a lasercutter. But the company, which does the cutting for me needs to have a 3D Model with the graphic already "wrapped" onto the tube.

The outcome should be like in the attached pic, but more accurade (the one in the pic I did freehand with a plasmacutter)

In the Curves workbench (add-on), there is a tool to map a sketch to an arbitrary surface. Maybe you can give it a try. ;)

Do we have a wiki page for it yet ?

Whats the name of the command to map a sketch to an arbitrary surface ? I'll create a page for it (Curves Workbench)

In the menu the internal command name is 'SoS' which stands for 'Sketch on Surface'.

I'll create a placeholder page called:
Curves SketchOnSurface
I'll add the icon soon.

I failed to mention in the video that you also need to have the Curves workbench installed to use this.

There is also a macro I used once to do this, I can't find it.

I know this isn't exactly what you want but maybe it will help. It's also an interesting use of the groove tool. If you sketch in 3D the cutout in the cylinder updates real time.
