Hi Adam,

> Is there any option to convert a sharp corners into soft?

There are a few different ways, which one is best kind of depends on the structure of your curves.

If you've drawn the curve with control points you can turn on edit points and delete the sharp control point.

If the curves have dense control points like they were a result of an intersection or something, then you might try trimming away some space between them and using Construct > Blend to put in a blend curve between them.

If your curve is planar you can use Construct > Fillet to round off corners.
