rooflights in flatroofs

[Anonymous]

hi!
when trying to place a roolight in a roof with only 1.5 degree fall, I get an error message something like --'roofs below 20 and above 40 degrees need special solutions'.
What's the special solution then?
How do I place the rooflight without the roof getting all 'messed-up'?
many thanks

Graphisoft should take note of this roof light issue as California has just implemented new engery use requlations that require all commerical buildings to be daylighted. That means hundereds of single story tilt-up structures flat roofs are going to have 120 plus roof light holes to be adjusted and re-adjusted with every change........ what a pain. ':cry:'

So, here's the "special solution" (workaround):

Change the pitch of your roof to be steeper than you intend so that you can insert the skylights without the error.

Now, select the roof (only). If you are 9.0, it does not matter what tool is selected. In earlier versions, select the roof tool. With the mercedes cursor on any skylight hole edge (if you are changing all), or on the top or bottom edge (if you are only changing those two), select the edge angle button in the pet palette as shown in the attached screenshot. Make the edge (or all edges) perpendicular.

Finally, change the pitch of the roof to the pitch that you originally wanted.

I "believe" you can simply place the skylight without changing the pitch, and make perpendicular just the angle on the upper side of the roof hole.

Good tips get better by time! This one tasted just like a good old wine today when I helped out a client!
