Can`t revolve as a wall in creo sheetmetal.

Can`t revolve as a wall in creo sheetmetal.

Please help

 

I want to design a new part using Creo sheet metal. I`ve attached the part which I was able to draw, but problem is I cant  revolve it as wall nor I can provide thickness to the same. without thickness error in reading mesh occurs in ANSYS 16.1 . I was able to creat simple hollow cylinder with thickness of 1 mm but I cant create this part with thickness. it fails to generate.

 

How can i modify my design with having thickness or how can i draw new one with thickness?

Could you make a screenshot of the part ? I can't open it, I get a message telling this has been done on an educative version.

Thank you for your attention and sorry for this trouble. Here is screenshot of part.00.png

Following is the screenshot of part drawing.

Also I`m facing problem in revolving sketch of this cylinder. I want to revolve it around x-axis but it says `all entities must be on same side of revolving axis` even though they are on same side, see by yourself (this happens after i`ve provided thickness of 1 mm under family table (in Tool menu) otherwise i have sketched upper part without thickness).

It won't revolve because the in-sketch axis is automatically using the first centerline you sketched and I expect you sketched the vertical one first to mirror some entities.

Since that was the first one, and you have entities on both sides of it, the error message is correct.

You can delete the vertical centerline, but may have to re-do the symmetry, or manually select an axis. I've forgotten which since a couple of decades of remembering to sketch the revolve centerline first has eliminated the need to do anything different. In any case, once you know it's easy to remember.

Thats what I thought at first, but after drawing it with only x axis and without using mirror command problem is still the same (I cant revolve it)0000.png

The first problem you had was the axis of revolution. The new problem is that the section can't be thickened correctly.

I would try eliminating the semicircles that form the ridges or adding fillets where they meet that are at least as large as the desired material thickness.

Thank you for your generousness, but this part is just outer cover, whole assembly looks like below and some rings are yet to add at ending. I have done all assembly and run through ANSYS CFX but error occurs saying that error reading mesh (its because I can`t add thickness to it). Are you suggesting that I should draw it in Solid?

Unless you need to "flatten" the part, I assume this is a tube that is necked down on the ends, create is as a solid.  You can revolve it as solid and shell it or revolve it  as a surface and thicken.  Shelling give you the ability to change the thickness of some walls.


There is always more to learn in Creo.
