Dooropening

[superjari]

Hi all,

Im trying to model a building, but unofrtunately the base drawing I got was full of lines that do not connect completely...

Now I'm trying to make a door opening, but a part of the opening can't be subtracted, at least, It doesn't work for me...

In the file above I've drawn three arrows where the problems are...

If someone can help it would be appreciated...

I played with your dwg but without luck. It happens to me to, my guess is that it is an internal error of a solid modeling routine. I typed SOLIDEDIT, than Body, Check. The answer was: This object is not a valid ACIS solid. From my experience, no solid modeling command will be accepted for this invalid object. The easiest way is to remodel your solid. If somebody know a way out from this situation, I will be happy to read.
Sorry, I give you bad news. My only hope is you don’t use to cut the messengers had.

Hi there again
I already made the wall all new, the Vizwhiz told me this:


yes i dont think that you can work with the old walls, i have had this problem before, it is called - isolated instances of intermittent singularity, what a lot of words. when there is just a pixel of information left over that is not subtracted properly from that point on the entire dwg gets wierd, i had this problem about 6 or 7 years ago on the project for the phoenix suns basketball proposal

a friend of mine (who is/was a nationally known autocad expert) spent hours going thru the entire dwg file project 1 3d solid at a time until we isolated the problem then corrected it from that point on then the project worked, but if there is a problem with something the entire dwg is corrupted unless you create a new wall or entity to replace the old one

so nowdays i make the subtract box 2x as big as the part i am subtracting it from
