Need help with Barrel-Vaulted Roofs

Anonymous

Got a slight problem with the barrel-vaulted roof tool. I'm trying to make a curved bit of glass, using the barrel-vaulted roof tool. But when I draw the roof in 3D, all I get is two pieces that isn't curved at all. Anyone who knows what I'm doing wrong?

The measurements of the piece is:

Length (x) : 750 mm
Width (y) : 600 mm
elevation (z): 125 mm

The segments of your curve are set too large.
Change this in the Magic Wand Settings.

Set the Magic Wand to 36 segments per arch, Best match.

Despite your great tips, somehow I can't get it right. Is it too much to ask if someone could show me in detail, how it's done? Would be much appreciated.

Hi there,
I had this problem too.
You need to go into magic wand settings, change the segments along arcs / circles box to 36 (even if you have checked deviation from curves less than option).
Drawing barrel vaulted roofs is easiest in the 3D window.
The first line that you draw is the straight line across the bottom of the width of the roof (it won't be part of the roof, but is the horizontal plane that the roof sits on). Then depending on the option selected in the pet palette, you can drag a semicircle (or other shape) upwards to create the dome. You then drag the dome out to the desired length.
It is much easier doing this in the 3D window, as you can see exactly what you are getting.

The trouble I had with it today is different. Perhaps someone can look at the image and tell me why it sometimes looks normal, but then in the elevation image I get the splayed roof elements?

Have you adjusted (eg slit) any of the roof segements. Occationally this can send out a rogue node giving unpredicable results. Not sure how to fix it.

atab,

Show us your barrel vault if it is not to much bother. My advise is the same for any "automatic" thing. Try it once or twice, if you can get it to work great, if not forget it.

Just model the parts you need using the profiler or something. In the end it may be better and faster anyway.

I agree, I just deleted the rogue roof segment, can't tell the difference in the drawings, etc. Nice to know I am not the only one tweeking things to get it right.
