How to turn vector into round curve profile

[chatofking]

I want to make a round curve profile from this

into this one

What should I do??

You can shape it with a Meshes and convert it into a curve.

Add a bevel modifier to this curve. Experiment, test things, break’em all!

Hi,

You meant something like this?

If so, you can achieve it by starting from curve romb.

1. Add a rhomb (Shift-A, Curve → Rhomb) and rotate it on 45 degrees on Z-axis:

2. In the left bottom options panel, uncheck “Cyclic” option as shown below:

3. Now, select your rhomb, RMB, Convert to → Mesh, switch to Edit Mode, and connect those two vertices.

4. Convert your mesh to curve again.

5. Add a Bevel modifier, switch from Edges to Vertices and add about 10 segments to it:

6. Convert it to a Mesh again and then again to Curve

7. Now go to your Curve’s settings and under the Geometry tab, change the value of Bevel’s Depth to something like 0.06 (by changing the resolution value, you able to control the smoothness of your bevels’ corners)

P.S. If you want your object to follow the path (curve), you may do something similar, but in this time, add a Curve modifier, instead of inreasing the Depth of your curve. There’s a lot of YouTube tutorials out there on how to work with the objects following the path.

Hope that helps

Cheers,
Sergey
