3 Sided Surfaces

[hbarea]

I am looking for suggestions on how to create 3 sided surfaces. What commands I could try? Any special technique or procedure I should look into? Thank you in advance.

If you mean nonmanifold part. I do not think UGS supports them.

 

[ewh]

It would only have to be non-manifold if the sides were flat.
You could sew 3 non-flat surfaces together or trim a block to such surfaces. There are many ways to do it, but the question is too vague to help much.

You could try a Studio Surface 1x2.

Or you could create a Through Curve Mesh, with the first Primary String being a point.

I hope that this helps!

N-Sided surface might work as well, but like Chris, I feel that Through Curve Mesh or Studio Surface 1X2 probably would return much better results. You can only create a Studio Surface if you have a Shape Studio license.

Here is a couple of threads from days gone by on this subject. I make no guarantees on their usefulness.

Feadude:

I do not mean a non-manifold part. I am trying to create a surface and then thicken it.

Ewh:

I will try to explain better bellow.

Vikingbro:

I tried a Studio Surface 1x2 and a Through Curve Mesh (with the first Primary String being a point). Since in both cases the isoparemetric lines in the v direction flow into a single point; there is a kink in the surface at this point, which prevents me from thickening the surface.

Nkwheelguy:

You are right, I tried the N-Sided surface, but the results were not good, the surface is not smooth and it can not be thicken.

Cowski:

Thank you for the information.

Everybody:

I will try to explain better. I am trying to create a close ended surface, which I am going to thicken. What I mean by close ended, is that my guides and sections (or primary and cross) strings are tangent at four points. If I create a single surface, the quality of the surface at these tangent points is poor because the u-v lines are flowing into a single point (singularity) and the resulting surface can not be thicken. If I divide the surface in patches, I end up with patches that do not have 4 sides; these patches have the same problem I just described. Is that clear as mud or what? Thank you all for your suggestions. Let me know is there are any other suggestions.

 

[Xwheelguy]

Again, hard to imagine without seeing your part. I believe I understand the 3-sided concept, but your second description has me totally lost regarding the patches. Did you try creating a good quality surface (like what you'd get with Through Curve Mesh using a point as the very first primary string and assigning tangency at the point as well as along the 3 sides)? If that still won't thicken, try Extracting a B-Surface from the TCM & then thickening the B-Surface.
