Curtain Panel Area Broken For Sloped Glazing Roof

[JOfford_13]

The area reported by a curtain panel is wrong after performing the following operations (see video for demo).

1.  Create a Roof By Footprint

2.  Assign any Sloped Glazing roof type

3.  Create one curtain grid line

4.  Delete the curtain grid line

5.  Rotate the roof element, in plan, by something other than a 45 degree interval

In the example the correct area is 100 SF.  The farther away the roof is rotated from 90 the worse the error in area becomes.  Rotating the roof 30 degrees from vertical produced an area of only 50 SF, half of the actual area.  At 45 degrees from vertical the panel reported the correct area.

This appears only to be an issue with flat sloped glazing roofs.  It also seems to behave fine before the curtain grid line is added and removed.  Please advise.

Yes I can replicate it.

In case you are interested on how to fix it:

Interesting work-around but easy to forget and very time-consuming

[ToanDN]

Correct. By the way, you only need to change one grid orientation, not both like I did.

Hi @JOfford_13 

Currently the team is working on an Improvement feature regarding this issue for Surface Area Calculation for Single-Sided Panels

Please check back in a few weeks for further updates on this.
