surface modelling

 how to solve such errors ? how i can trun those red free edges to green one

[davebYYPCU]

The vertical faces must at least reach the cylinder, and not penetrate the cylinder surface.

Same for the cylinder, must be trimmed to the rectangular (top view) faces.

so that edges of each body are coincident.

Might help….

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Hi,

Why don't you create the object as a solid from the very beginning?

Thank you for your effort

And also I know that it's very easy with solid workspace but I'm learning surface modelling so I was just practicing...

Also if you have some good resource to practice or learning surface modelling please share

Practicing surface modeling on designs that don't require it, has negligible  learning effects!

[22JE0190]

Ok I will keep it in mind from now. Also, If you have some resources or a way to learn it better you can share

I see nothing wrong with learning surface modeling techniques using geometry that doesn’t really require surface modeling techniques. In fact, I have written tutorials that do exactly this for beginners.

I notice that you did not Attach your file here?

Show me yours - I show you mine.

I would agree, as long as the student does not move ahead after these basic exercises to start modeling a boat or airplane fuselage. That requires some understanding of what a NURBS surface is 😉

So you're trying to say that even on the surface you have no idea how cad modeling works.

Are you trying to do this. You're trying to model surface relationships?

If you want to do it after the model is created. Split body works. Because, trim will remove sections you need. And, split face doesn't need to extend the split tool. But, there is no way to remove the surface from the body surface. I'm not sure if there is a way to do that. I would prefer that.

In principle, every construction should be kept as simple as possible. This is often possible with solids.
Surfaces should only be used where there is no other way or where it has certain advantages.

This is a simple example that you cannot create with solids.

Spot on! That is exactly what I was trying to say (but kinda didn't).
