Sectioning Surfaces in Drafting
Sectioning Surfaces in Drafting
(OP)
I'm currently trying to set up some standard drawings that I can add and remove parts into and generate drawings quickly.
The drawings are generally 1 or 2 views with sections through parts at pre defined sections.
The problem I am facing is that these parts tend to be only surface geometry and not thickened.
When I section surfaces I find that UG is very tempramental and will section some of the surfaces but not all of them.
Has anyone else come across this and found a "neat" solution to make sure UG sections all of the surfaces.
I want to avoid using wavelinks and modeled in sections as the whole point of the drawings is to save time and allow users to "drop" parts straight into the drawings hit update and then get a usable drawing without having to fiddle with them.
Any help (as always) is very much appreciated.
Cheers,

You might also want to include a single point in modeling for quickly re-defining the section line on the Drafting side, if you find the surfaces are all over the place in relation to the origin.
I've never ran into a need for sectioning surfaces on the Drafting side, so these are just some shots in the dark. Sorry I couldn't be more helpful.

Some people are like slinkies....they don't really have a purpose, but they still bring a smile to your face when you push them down the stairs.

Thanks for the reply.
The surfaces all have the same modelling tolerance.
They're all modelled in UG and the default tolerance is set the same for all users. It's a major no no with us to mess with modelling tolerances.
Positioning is not an issue as everything is modelled at absolute coordinates.
I've also tried messing with the view tolerances as sometimes this cures iso view display problems, as well as some of the other view preferences but it's had no effect.

The drawings would be used regularly with constantly changing surface geometry. This is why I'd like to use the drafting sectioning as if you just add a different component to the drawing part it would just require updating the views and the drawing would fill itself out.
I can't see why UG would have more problems sectioning a surface than a solid. If anything I'd expect it to be easier.

Ideasuser, the O.P. said that all surfaces are created inside UG.
But you possibly open a new opportunity: save the file in Parasolid format, and read it back in UG. Due to the fact that the subset of entities of standard Parasolid is less extended than the proprietary format of UG, many entities are "regenerated" during the conversion and, in some cases, this can fix problems...
