I'm new here, so excuse my lack of knowledge.
I'll try to be straight.
Here is a sample of what I want to draw, I have something like 40 of them :

My starting point is an svg curve.
Imported it in Blender, it looks like that:

Then I convert it to a mesh and, at this point it looks like that:

I then remove some vertices by hand that seams unnecessary. After the removal, the mesh looks like that:

I understand the vertices that are on the curvy parts of the mesh are necessary, but maybe the ones on the straight parts are not.
Maybe I'm wrong to do this simplification, but I have the feeling, that making changes on the shape is easier with less vertices/faces. And maybe it's faster to draw too, I'm not sure.
Anyway, the removal operation is painful and slow. And I want to fasten then process, as I have multiple shapes to draw.
Is there a way to do this faster ?
- Automatically remove those vertices ?
- Do not generate them at first place ?
- Automatically merge the faces once extruded ?
Additionally, it other non-destructive simplification could be automated. Any kind of advice ?
Thanks a lot for reading even if you don't have any help to provide.
