Bad Shape when adding objects together

[egkteam]

I don't know if this has been posted before or not, but anyway here it is:

If I have 2 objects, which I want to add, i sometimes need to disable grid first, or not it wouldn't add. And what I mean sometimes is 3/4 of the time. And usually the resulting object becomes not straight especially when it is really small. What I did is set the transparency to 99% since with transparency less than 100% it becomes neat again.

I don't know you understand this or not because it is hard to explain

Add them when they are big, and then make them smaller.
