How Do you create breaks in circles

sevrick

Ok I use the Circle command to make a perfectly round room but when I go to add a door on one of the sides it doesn't make a break like it normally does when you do it with straight walls. I also tried doing a manual break but when selected about the width of a door in a break it broke the whole circle except for where I wanted the break. So it did the complete opposite of what I wanted. As of late I have been painstakingly piecing together arcs then drawing a straight wall so that I could achieve a proper break and thought there has to be a better way. Plz help me with this

When you break a circle you must select the circle on the part that stays, in other terms, you must not select the circle on the part of the circle you want to erase. On a line this isn't necessary since there isn't any doubt about the parts to keep, but as a circle is, er, cirlcing on itself, the break tool uses the selection point to determine the part to keep, not the part to erase. Hope it's clear...

You can also split the circle twice and erase the door part afterward but it's only useful if for any reason it can be useful, otherwise I'd go for the break.

Lastly, you can split the circle once somewhere on the gap and then trim to intersection with the straigth wall lines. Trim to Intersection can be somehow tricky with arcs, though, it tends to keep the greater part whatever you selected, but it's probably due to the difficult math of the thing and has yet to be solved.

You should be able to use the wall-breaking doors on a circle, as long as the circle is on the correct layer (WALLS). Check your circle's properties to see on what layer it is.

Wow I don't believe it. you were right Ralf. I can't believe I missed that. Thanks everyone

Unfortunately the success ratio is still fairly low.
