Lines can not intersect each other. The highlighted lines currently intersect.

Hi all Revit users, wishing you all a prosperous second half of 2022 !

Just as my title says, I keep getting the same error msg as the following.

"Lines can not intersect each other. The highlighted lines currently intersect".

None of any perpendicular lines actually run past through the other. They are perfectly co-incident. 

I try to make the ends of the perpendicular lines just touching without the end points connected co-incident.

As well, I use the trim tool to trim out the outermost parts of the lines mentioned above. 

Does not work but only displays the same error msg. 

Then, Revit picks other lines and says the same error msg. 

This is fantastically annoying. 

What can I possibly do ?????

Those of you who know, please please please share your tip as detailed as possible ! 

Greatly appreciated in advance !

When I click either one of the squares, they move together as a group. 

The Exlpode command greys out.

Several ways:

- create two regions and make them a group

- create one big region, add a line, and make them a group

- create one big region, add a line and constrain it the region edge with dimensions
