Good Morning
In one of our projects, when a plan region is modified, the view range modification is happening outside of the plan region as well.
See the snip below.
In the upper-left corner, there are 3 bleachers. There are no walls under the bleachers. Thus we need to show the bleachers in that corner from the top. There are bleachers at the bottom of the screen. Those need to be shown as cut because there are walls and rooms underneath them.
When you apply the plan region it cuts both the bleachers in the upper left and the bleachers in the bottom.
See snip below. This happens regardless of where the plan region is placed in the view.
What would cause the settings for a plan region to apply to the whole view instead of just the area of the region created?
Thank you for your time.
Is there in-place family spanning both of those object?
All (4) Bleachers are four separate Generic Model Families containing a 3D AutoCAD Import or Sketchup model.
There are no in-place families in the project.
When you use a plan region to cut one set of bleachers, all 4 bleachers get cut.
Including the the bleachers families outside of the plan region.
Oh that explain it. CAD & Sketchup objects will behave unpredictably if you set them to cutable in family environment. They work fine if they are not set to cutable family category. Often I would create them as Revit family just to avoid these issue. Other method you can try is to placed those CAD or sketchup into massing family environment. Check the link below.
syman2000: I read the link and the pages that are near the link.
I did not know there were cutable and non-cutable families.
The bleacher families are Generic Models, which are a "non-cutable" family.
The "Cuts with void when loaded" is also off in these (4) families.
Because these families are set to a non-cutable familiy category, they should not "behave unpredictably".
I attached them if I am missing something.
Thank you for your time on this
I changed the family categories on these bleacher families.
These bleacher families, whether they are in a cutable family category or not, are being changed outside the plan region.
Even when one bleacher family category is different than the others.
If anybody has ideas, I'm open to them.
This usually happens when there are elements that extend beyond the desired extents of the family. It could also be that there are elements far from the origin. Vet the families carefully and fully keeping an eye out for these types of things.
