imported files from toptron

[Alex37]

Good morning to all I imposed a .x_t file from toptron format, I managed to open it with some errors that didn't compromise what it needed, but going to make a set I couldn't do the matings, selecting only one face and the other I couldn't select it.
you have to convert something further or are just the faces that do not have the same geometry and do not mate. . .
If so, is it impossible to do anything together?

If there were any mistakes?
What mistakes?
try to say abra cadabra with a wand in your hand.
Would you turn with a car that has the light of the engine light on?
Would you design with a file that contains errors?

It gave me errors of faces and games, small hidden faces, the file I needed to create renderings and therefore I went ahead, but I would like to solve the problem for the future. .
