Surface perpendicularity problems with Extruded Solids
Surface perpendicularity problems with Extruded Solids
(OP)
Hello,
I'm not trying to flame UG but I think we all no there are some dimensional accuracy issues with the software 2.00" becoming 1.999999999986 etc.
My co workers and I have run into problems assembling files due to non perpendicular surfaces from simple extruded solids in UG. Has anyone dealt with this before and if so are there any ways to fix this with Part Cleaning or System accuracy decimal places?

RE: Surface perpendicularity problems with Extruded Solids
Do you see the dimensional problem in conjunction with the non-perpendicular surfaces? It seems like those would go hand in hand. If you see dimensional oddities independent of the other problem, then I would start looking into it.

All of the extrusions are directly perpendicular to the sketches or curves, but when doing an angle analysis of face perpendicular direction the values do not equal 90 degrees.

RE: Surface perpendicularity problems with Extruded Solids
What are you measuring the angle to? eg one of the faces vs WCS Z direction?
How about your modeling tolerances, what are they set at?

It is best not to mess with "listing window decimal places" setting which is in the preferences-user interface. Our draftsman/system administrator set it to 6 digits and now we have set it back to system (UG recommended 11 digits),
and we have problems like yours. I understand listing window is for display purposes but its values are used for construction values using copy/paste.
I hope this helps.
