Highlighting a Bounding Box (of a Group)


So I now have a collection of window and door groups nested within my main wall group (wall assembly).

As the user mouses over the various windows or doors I will have the tool determine if the point is within the bounding box of the window or door group and then base its selection on that criteria.

However I thought it might be nice to have the tool highlight all of the window and door groups within a selected wall group. However, I don’t want to add all of these groups to the selection set but rather just draw a thick green line around each bounding box of each window or door group of the currently selected wall so that the user gets a clear indication of where they need to click to select a particular opening.

The code to create the highlighted lines will reside in my draw method of the tool. I am wondering if there is already a nice method or algorithm someone has devised that will grab the eight points of the bounding box and draw the lines.


I thought Thomthom did something like this. Check his TTLib2 code. (Might be at BitBucket)

After giving it some additional thought it probably isn’t worth the trouble but it does lead me to another question.

Up until now when utilizing the draw method within a tool for preview purposes I’ve only ever drawn lines or dashed lines. Is there a way to draw a face?
