Hi all, I think this has been discussed before (heck, I may have even asked already) but I am having trouble geting some of my roofs to work out for me. I have a series of roofs that all have the same slope, but different eave heigths, and in some cases different ridge heights and locations.
See attached. the yellow highlight is where I have place a reference plane that is what I have aligned my roofs, and my section view to. The red roof shares an edge of the adjacent roof (I used pick line to select that roof edge). The slopes of all roofs are set for 7 over 12, and in the red roof, I have adjusted the offset from base for the two end walls (slope defining). One of those edges was made by selecting walls, with an overhang, and the opposite end was made by mirroring the first line, and then drawing a new line over it (deleting the mirroredline).
Questions:,
why does the ridge height not match the adjacent roof? How can I get it to match?
what technique do you use to determine what base offsets to make for sloped edges? for me I draw detail lines, do trig based on where I think the roof is being measure from (trial and error)
Right now, the ridge is aligned horizontal as I would like it...but I need to move one slope defining edge a few more feet away from the ridge. when I do this, the ridges do not align horizontally, or vertically. So, how do I make that happen?
And, my technique for creating the section is to snap to the ref plane, and then nudge it back fro the line about 1/64" of an inch, so that I can see both roofs (the one selected for one edge, and the red roof). Is this the right way to do this? If no, what is better way?
thanks.
NOTE: I cannot find the insert image button....has something changed at AUGI?
