hi im having an issue with the union command of two solid objects, keeps giving me various errors most common is 

The Boolean operation on solid and/or surface bodies failed.
Modeling Operation Error:
Coincident face_face_ints with different body vertices.

saw on another thread issue was resolved by moving the object to intersect better but this doesn't work

struggling with this please help

Zoom in really close, they aren't touching; move the dome down .01 and it'll work.

I tried a reverse union by drawing a big box over your solids and subtracting one by one from the box.

I learned that the problem is with the bottom solid. After looking at it closer it looks like some edges which should be one whole are still divided from each other.

How did you create the bottom solid? I presume you drew both parts and performed a UNION command there as well? or am I wrong?

union should also work on solids that are not touching, although if they were meant to touch, then yes this would not work and you would have to move them in the correct position or edit one of your solids before using union.

bottom piece was made with two presspulled pieces union-ed together from a basic line drawing that need the flatten command to work, i think the original drawing wasn't exactly on the plane and needed flatten in order to presspull it, it seemed that when i used the blend lines command it caused presspull to fail

Boolean issues are usually caused by a union that would result in EXTREMELY small slices where two solids intersect for part of a common face but don't for the rest of the face.  Either separate the solids such that they do not intersect at all, or such that the entire face intersects.

ok so i can't presspull a flat drawing if it has blended curves here is an example of two drawings one with filleted curves and one with blended curves.

i would like to be able to presspull things with blended curves as it's easy to use as a dynamic fillet command which looks nicer for the project im working on, but if i use the flatten command on it it fixes it but decreases the accuracy of the line and i think that's why im getting the errors when trying to create a union with the model
