Hello,
I've been trying to get these this mirror'd solid to union into 1 solid to no avail. Any ideas?

Is that what you want?

Hi dodeqaa, it looks like some of your surface have a little bit of a slant to them instead of being directly in line with a world axis.
For example this one here:
If I zoom in a bit on a side view I can see the surface, if it was tightly aligned with the mirror direction it would only show the edge from the side and not some of the surface as well:
So the problem that creates with the booleans is that it's difficult to intersect surfaces that are barely grazing each other with overlapping surface areas.

So one way that will work for your case here is to draw a line down the y axis and use boolean difference to cut the 2 solids with that centerline and discard the pieces in the middle.
You should then be able to boolean union the 2 remaining pieces together. That helps because it avoids trying to generate an intersection between 2 surfaces that are just barely skimming over each other's surface area but slightly off.

Dear Michael I have got a question.
After creating an object using commands loft, swipe, network, etc; control points are gone?
I mean when user presses "show points" he/she would not be able to see any points?
Is it possible to see some points after creating objects using those commands? (Like when you create a box and u still able to see its corner points after it's creation)

Hi Psygorn, some info on control points in the FAQ here:
http://moi3d.com/faq#Q:_Why_does_show_points_work_for_some_objects_but_not_others.3F
A box is a special case where every edge in it is a natural edge of the underlying surface and that's why you can see points on it. When an object has a joined edge that is not a natural edge of the underlying surface then that's when you won't be able to show points since if you moved some points you would pull open a hole in what is supposed to be a joined edge. To turn on points in that case you need to use Edit > Separate to break pieces out into individual surfaces. You can always show control points for a single surface that is not joined to anything.

Hello Psygorn and Michael,
Psygorn: That is exactly it! Thank you for taking the time to fix it. I appreciate it,
Michael: Thanks for the in depth response. I didn't see that the plane was skewed, and now I know how to check it with the orthographic views and zoom.
