Split Face Line Length

[daycircus]

I'm trying to wrap some sketch curves around a cylinder. Since the design is symmetrical, I want to project 1/4 of the design, then pattern it 4 times. The cylinder is 4" in diameter, so I create sketch features that are 3.14" (pi*D/4) wide. I assumed that a projected line (which becomes an arc on the face of the cylinder) would have the same length, but it is much shorter. How do I calculate my line width so that my pattern edges will line up?

Hi,

if your goal is to project over the full circumference of the cylinder, sheet metal modul could help you.

1. create sketch with "broken" circle

2. sheet metal flange from this profile

3. extrude flat area

4. unfold  the zylinder > select flat area

5. sketch on the unfolded sheet metal > import your dxf or svg profile

6. extrude profile

7. refold it

 ready!

That might do it! I'll give it a try. Thanks!
