Doesnt see lines as intersecting

[[email protected]]

Mc2018 problem. I am trying to trim lines using trim/delete, but its saying that the lines dont intersect. They do as far as i can see....

If they should both be lying in the same plane, select the plane, set the Z depth ( if you know where they should be enter it, analyze the position of the ends to determine if they are not coincident with the plane) and project them (move not copy). They may be slightly off the plane, just a 0.0001 or less (which might not be apparent) difference will give you an error.

This is quite common on derived geometry from models

Sometimes if you are in 3d it won't trim but 2d it will

As stated above be on the corrected plane and switch to 2d.

Make sure you are in 2d mode and the correct construction plane

If they intersect , they will intersect in 3d or 2d .  In cases like this I usually xform project onto the plane in question. A projection of a wireframe element onto it's own plane will not alter it , only the elements not lying in the plane will be projected and also a parallel arc projected will remain an arc ...

Ok, I'm good. Thanks guys. I had it in 3d. All I had to do was switch to 2d and the problem went away. Yes, I'm a newb.

I've had it trim in 3d fine then other times not.

Sometimes a solid is involved
