Quirky 2D Poly Tool Inner Boundary Mode

[Jim Smith]

I sometimes use the 2D Poly Tool Inner Boundary Mode in the Annotation Layer to dress up a plan, section or elevation. This seems to work well except often it seems to be a question of how you hold you mouth to get the tool to do what you'd like it to do. Here's an example:

 

Here's a section (BTW, the dotted lines aren't visible in VW):   

 

Here's how I think it should fill (I know I'd have to ADD surface to the two grey pieces)  

 

 

Here's what I get: 

 

My question is there some hidden setting that I can change so I have better control of this tool?

Jim,

 

I think its because its reacting to the linework of the viewport, not the surface shapes of the 3d geometry.

It is possible to hold down shift and add areas - so the grey area, for example, could be done with two clicks, the second one while holding shift.

Thanks Kevin, but I actually think the tool is finding the 3D geometry behind stuff.

Interesting. I did a few tests before I originally posted and it only seemed to find the 2d linework. What is the rendering mode of your Section viewport? Is it just Hidden Line or is it a combination of modes.

It's a Hidden line render of a Section Viewport. The counter the monitor sits on is cut by the section & is an extruded 2D Polygon, extruded from the top. (The Millwork Company is working directly with the client). The shelves in the background are Symbols produced with the Bookshelf PIO.
