Mesh surface

[Barn Light]

Hello all,

I am useing AutoCad 2011, and having trouble createing a surface out of the lines shown here. The three colors represent three different shapes. I have tried all of the commands in mesh surface but I must not be doing something right. What command should I be useing?

I must be missing something on my Ribbon. Where did you find Mesh Surfaces?

[Barn Light]

Sorry. it's just mesh, next to surface

[ReMark]

Not sure why you would need all three shapes as you call them. I used a single profile swept along an arc to create this.

 

 

Hmmmm....seems I have a surface and not a mesh. Sorry. Back to the drawing board for me!

Is there really a need to be sarcastic?

Is there really a need to be sarcastic?

 

Say what? I'm not sure where that came from.

 

Anyway...here is the solution to the problem.

 

You need to start with a profile and a centerline. Then all you need to do is use REVSURF to create the mesh. Like this:

REVSURF can be found on the Mesh tab > Primitives panel (far left hand side of your Ribbon).

 

There are four buttons for Revsurf, Edgesurf, Rulesurf and Tabsurf.

 

Is everybody happy now?

I tried that, that is not the shape I am looking for. The green arc (shape as I call them) is different from the blue ones, so a revolved profile of the blue profile does not match the green profile.

The eyes are always the first to go. I could not tell from your image that the green profile was different from the blue ones. Can you post the dwg file?

[Barn Light]

I'm trying, I have not posted a drawing yet and haveing trouble, it say's the file is to large.

[ReMark]

WBlock out the geometry you've shown above. The drawing file that you create will be very much smaller. Post that one. Call it something like MeshProfile.dwg.

Have you tried using EDGESURF? Pick the curve at the very bottom and the three blue lines (two straight and the half of a circle).

 

Oops. Doesn't quite do the trick. Looks like we need the top (horizontal) curve as well to influence the final shape of the mesh.

I just tried using EDGESURF, no luck.

I got it, well something that will work anyway, using the sweep comand. Thank you for your help though.

[ReMark]

Sweep? And it's a mesh?

[kencaz]

I think Loft will give you a more accurate surface...

 

[Barn Light]

No, like I said it will work for what I'm doing. I just needed a surface, I guess I'm getting the termenology mixed up surface mesh????? I used two sweeps, a blue vertical along the bottom red and the top red along the center green. the second one I had to trim.

[ReMark]

Terminology mix up. Yep, think so.

 

There are solids, surfaces and meshes.

 

You had me confused for sure. Probably could have come up with the answer 13 posts ago. LOL

 

No harm, no foul. Glad to hear you got it solved. That's all that counts.

It can be made with 3 meshes ( EDGESURF ) You would need to break certain edge lines in order to 4 connected edges. -David

It's that "four edge" thing that always gets me. Thanks David. I knew there was a way to do it using Edgesurf.
