3D Section Planes

Question

This is a well liked feature in Google Sketchup and Autodesk Revit. It is a 3D view that has movable planes to make cutaway sections of the model.

It seems to be possible to have this in Vectorworks, since 3D sections are already possible. The only thing it needs is the ability to have a graphic section plane that moves in 3D views.

This is an absolute need. I have an associate who argues that without that capability Vw is not a genuinine 3D program. While I don't agree with him it is difficult to defend Vw's lack of that capability when most of the other architectural 3D programs do have it.

Yes.

However, as comes to editable 3D-sections, things are not necessarily simple and easy, because unlike in at least some other 3D-programs, in VW we have constructs that cannot be edited in arbitrary 3D-views.

In conceptually simpler programs, things are, well, simpler.

Except for the working plane, which can be moved and rotated in 3D views.

And it's easier to draw shapes and lines in 3D views with Vw2010 - which helps to bring it in step with Sketchup's ease of 3D drawing.

I do agree that sweeps and extrudes do fine in 2D editing mode.

The movable Section Plane would exist mainly for model presentation - not for editing. It would function just like the Section View line, except as a plane.

If the Design Layer section plane protocol is implemented properly it will just be a partial view of the whole virtual model and therefore editing the model should be possible from within those views.

The gains in communication need to be complemented by the ability to make changes to the model from those views and to generate all section views as Design Layer Viewports. Perhaps it could also generate the plan views given that they are essentially horizontal sections through the building.

Should it? If you have even an extrusion, in an arbitrary location & rotation, what would you edit? How about a complex solid with a Boolean path 20 steps deep? A symbol with in a symbol? A parametric object within a parametric object? A wheel within a wheel?

I have the feeling that what you are after is a fundamental change of VW's 3D-concepts. For better or worse, of course.
