Slab - cut orientation in 3D

OBERMEYER
Booster

Building oriented orthogonally to view in plan except one wing, which is designed to be angled out twenty degrees in plan view.   When cutting the angled slabs in a 3D view, by right clicking slab and selecting the icon with minus sign, the default cut orientation aligns to the project north, not the slab direction.  It ignores a grid/edit plane that is oriented to the twenty degree angle.  We an create a hole orthographically in plan view, but not 3D.   Suggestions?

Another limitation.  Got it.  Thank you for clarifying.  Frustrating as some of us use the rectangular geometry method a lot.  

 

This issue is related to another concern we have in setting up new projects.  We recently thought to orient a project site to view north, and then rotate each building view to the preferred orthogonal orientation for best fit on layouts.  So, for example, if a building is a 'V' shape, why bother starting with one or the other arms of the 'V' oriented orthogonally to the view?  Why not just start with site plan north oriented to the non-rotated view with up on screen or 'y' axis as north.  Then rotate each view on layouts.   Easy, right? 

 

But then we get issues like rectangular geometry method in 3D not working for us even though we set a new grid/edit plane to the preferred model orientation. 

 

Any other surprises here? Other limitations in this setup?  

 

 Is it best to simply setup the model with one preferred orthogonal direction to the view and then use Set Project North tool?

I share your frustration and was planning on making it a wish in continuation to this wish which also is related to how graphical modeling in AC could be enhanced. The current setup with coordinate systems, construction grid, snap grid, edit plane and then grids as separate objects is really in need of a redo.  Being able to define multiple coordinate systems and being able to easily choose which one to work relative to is an obvious first step.
