Invalid Boolean message continuously popping up

[Anonymous]

Hi, I tried to use the proboolean command and now I cannot proceed with my building because the "invalid boolean" message keeps popping up with an error. Any idea how I can get rid of this message and proceed? I cannot even close the window (and lose all the work i havent saved), thats how badly stuck I am with this error message. can anyone tell me how to make my file workable again?

If you provide a screenshot showing your Boolean objects, the modifier stack and the error message you are more likely to get an answer here. 

In the meantime, I will hazard a guess that you do not have 2 completely solid  geometry objects for your pro boolean operands .  Are you by any chance trying to combine a shape like a circle or a box with a deleted polygon as an input to pro boolean?  I don't have max 2020 installed, but in other versions proboolean needs solid objects as inputs.  If I am off base post the screenshot and I will try to help.

Hope this helps.

Sorry, Please disregard the above post.  I remembered this incorrectly, and cannot reproduce the error with proboolean using mesh with deleted polygons in max 2017.   There must be some other reason for the error you are getting, so the screenshot or a description of the objects you are trying to combine with proboolean are necessary to solve the issue.
