I am having a problem with shelling and offset of a parts I am making.
Both of the commands would fail at 99% in a complex geometry (pls see attached ) and by chance I have succeeded in the shell command in this case (only by luck)!
Could someone kindly point me out into the right direction as to how to overcome failures of shelling and offset srf for a complex geometry please?
Please kindly refer to the attached example, many thanks any help is much appreciated!
Hi Mori - I don’t know if it is possible to make many generalizations, things can fail to close up for a variety of reasons - in the case of OffsetSrf in your example, it appears to have basically worked but left some edges unjoined - if you ExtractSrf the surfaces at the naked edges and then rejoin them, as far as I can see it all work out pretty well.
@Wong_Mori - another thing to pay attention to is that the file tolerance is quite loose - .01 units - that is not out of the question for this object I would say - the details are not minuscule - but I’d still be inclined to model something like this starting with a .001 tolerance.
Thanks for your help. Yes, I noticed that either shell or offsetsrf can result in opened edges , sometimes a very small amount of offset say 0.1-1mm might get away with it but this thickness may not be always desirable.
So maybe, would it be a case similar to fillet edges where too large of a radius may fail the model? If so, what is the controlling factor for shell and FS?
