Re: what is geomcheck ? |

Most geomchecks occur as a result of the limitations of Pro. To get
reasonable performance, Pro makes assumptions about whether surfaces really
meet each other, as for many geometries a perfect match is impossible.
This can have a number of effects:
With very low accuracies, (where you use relative accuracy for models with
large bounding box dimensions, and then create small features in the model)
Pro will accept some pretty poor geometries which it may warn you of but go
ahead and create anyway. Upon casual observation these will look fine, but
when you zoom close into surface intersections, you'll see they don't really
meet up properly. It's a good idea to fix these (usually by forcing a
reasonable level of absolute accuracy, depending upon the sort of product
you are working on, a good level here will vary, but as aguide, if you're
working on, for example, large diesel engines, try 0.02, but if you're
working on auto size gasoline engines, try 0.01) as the gaps Pro ignores can
cause cross sections to fail, or geometry sharing of one type or another not
to work.
With very high accuracies, you'll have trouble importing non-native data
into Pro. You'll probably need to try a few values.
Sometimes, for absolutely no discernible reason (this is rare, but it
happens) perfectly reasonable geometry won't work Try varying your model
accuracy, and move your sketches round a bit. It's annoying when you cannot
create perfectly viable geometry due to the software being fickle, but thems
the breaks. All CAD programs suck in their own peculiar ways.

This is prasath. I am working in pro-e. I want to know what
geomcheck is. Why is it conserved as warning? Why it occurs ? what
happens when it is not considered during manufacturing
