Roof Layers

[Curtis Johnson]

Chris:

In X3, try this:

1. Select all your roof planes; make a copy.

2. While still selected, go to options tab and uncheck the roof sheathing selection box.

3. Change the thickness of the roofing material to 1/16".

4. Go to the materials tab and change the roofing material to whatever material you want to use for your felt/tarpaper. I changed the roofing to a leather material - in Plan Materials I made a copy of the material and called it Roof Tar Paper.

When I tested this, when I made the roof plane copies, I drug them off to the side and then in display options I made another layer called Roof Planes 2 and used that for my tar paper roof planes. I then moved them back into place with a point to point move.

Next I built a materials list and the roof tar paper showed up on the list with a slightly greater square footage than the roofing material for the original roof planes.

The interesting thing is that even though I have roof planes on top of roof planes, I can only select the original roof planes (Roof Planes layer) and I cannot select the tar paper roof planes (Roof Planes 2 layer).

That is only the beginning of the weird stuff. Next (try this) take a back clipped X-section of a test model. I wasn't so sure I could see the 1/16th inch thick tar paper like(where) I thought I should so I changed the line style for the Roof Planes 2 layer from a solid line to a dashed line.

The tar paper was there and it was where it should have been - right on top of the roof framing. So, to get it where it belongs, I would need to raise it up in the Z direction. However, not only was my tar paper a dashed line, but so is the roof framing. When I turn off my Roof Planes 2 (tar paper) layer in display options, "all" the roof framing goes away ... even any roof framing for the original roof planes! Maybe Chief doesn't like to have two copies of roof framing for section views.

I could get the tar paper to show in 3D overviews but with some unusual results as far as no fascia displaying. Maybe there's something else that can be done with the copied roof planes ??? to get better results ... don't know. You can play with it some and see what you get for results. Not sure why you want to do this but maybe this is a start to get you there. Good luck.
