geometeric series

[LuPo_81]

Hello, everyone.

most models I use are angular sectors of a toroid, described by surfaces. to create complete models, therefore I use the "geographical series". this method works properly with surfaces, but not with solids. in detail: I imported a surface model (from iges) that represents an angle of 30°, I closed the open surfaces, I joined everything and I solidified. select the created surfaces and create the series: if imposed repetitions at 30 ° the feature fails, while if imposed, for example, the repetitions at 30.5° works.
Who can explain why?
How can I do to create the correct model (solid!)?

I attach a banal prt that illustrates the problem.

Bye.
Have you tried to change the absolute accuracy of the part?

depends on the fact that you worked for surfaces. If you cover those surfaces with an angle of 30° the copied surfaces "intersect" and the merge operations obviously cannot work.
try to make the first feature of revolves directly as solid (why did it as a surface ???) and then do the series on the solid and everything is fine using any angle value.
do less feature and everything works!

your file can't open it is done with the wf5?
I'll give you an example.

(why did you do it as a surface?) and then do the series on the solid and everything is fine using any angle value.

the model the amount from iges and is formed by surfaces, what I posted is only an example model. the real model is more complex.

the merge operations obviously cannot work

However, if you remake the series on the union surfaces (excluding the "solidification" feature) and then make the merge of all the surfaces created by the series the model perfectly creates it, but the operation is long (imagine if I have a series of hundreds of surfaces) and then it touches me to solidify everything.

Have you tried to change the absolute accuracy of the part?

ehmmm... how do I verify this? If you can do it with the model I attached?

your file can't open it is done with the wf5?

Yes, it's in wf5. However the offset is not there, it was only to make it clear that if I put it as an angle of the 30.5° series everything works, while if I put 30° (as should be) fails the generation of the feature. place a test iges, who manages to make the solid model of the whole series of 80 repetitions?

I would like to ask you to explain the part completely different from the previous one.

the problem is not on a model in particular, it is on all. If you help me do it on any one, it's like I did it on everyone!
