Please can someone tell me how I can fix this, I cannot FILLET certain lines, and now a new one, when I use PERPENDICULAR SNAP, the meeting of my vertical line with the horizontal line misleads to a left point of the horizontal line, as if the encounter point has been changed from the vertical path.ThanksJaime

Hello autocadpape, are you using 3D ?If yes it should be simple to fix.If no then try and verify if you are in the UCS world, then open the properties panel ( Ctrl + 1 ) , select a batch of lines ( with no arcs inside ) and set to 0 ( zero ) the beginnings and ends.  See that print screen in French. If it doesn't work than try and test the MOVE ( do a test on a copied file, not the original ! ) :Move the objects from : 0,0 to 0,0,1E99 than remove the same objects from 0,0,1E99 to 0,0,0. This should be OK after.Please tell me ( us ) if this helped or not. P.S. Please note the fillet doesn't work on non coplanar entities but works with TRIM even if the entities are not at the same level ( do be done with a good UCS and viewpoint ). P.S. See also the related TIP here under : TIP 2248 : FILLET command reports "objects are not coplanar".

Did you try using the FLATTEN command?
