Drawing on a curved surface

Hello,

 

I'm struggling to find an answer to this problem.
I want to draw a line on a curved surface (cylinder in this case).

I can only find solutions to emboss or project a sketch, but that is not applicable in my case.

 

I have 2 axes protruding the cylinder surface, thus creating 2 points on that surface.

 

I now want to connect these 2 points with a line over that surface.

 

With kind regards,

 

Wouter

Please share your model along with an explanation of what exactly you want to model.

There are likely other workflows than a COS (curve on surface) that will get you what you need.

Hi,

 

I made a very simple example (attached).

You will see a cylinder with 2 sketches, each at a different location in that cylinder.

Each sketch has a random line that protrudes the cylinder surface.

 

I now want to draw a connecting line between 2 end points of these lines of the 2 separate sketches.

This line has to run over the cylinder surface.

 

I don't know beforehand, where these lines will be, since I use parametric dimensions.

 

Thanks already!

Straight line?  Clockwise or Anticlockwise?

Sketch lines need to protude, as you say, Loft a surface, and use the edge of this trimmed surface for your purpose.

I've worked with quite a variety of CAD and other 3D modeling software over the last 30 years. No need to dumb down "examples".

My experience over thousands of posts here in this forum is that usually users over simplify examples an then get frustrated when the narrow questions they ask receive narrow answers, which miss then the point.

Hi TrippyLighting,

This example is exactly what I want to do.
I still have to start my actual drawing, but I was thinking how I'm going to build it up.
And then I came across this problem...
