SolidWorks - talon problem

Hey guys,
We are new with SolidWorks and I got some problems placing my Talon in assembly.
First i downloaded the cad file from andymark, put it in SolidWorks, and let him parse the object. After that i did the following: I drilled 2 holes into a plate with the dimensions from the Talon documentation. I used concentric mate to place one hole in the talon with one hole in the plate and tried to do the second hole as well. I received an error that the distance between the centers is X, x was different depend on the angle of the talon.I tried to measure the distance between the holes in the talon with the measure tool and use the result, still no luck. I want to lock the talon so he won't rotate so i tried to take his side and make it parallel to the side of the plate (the plate is something like a box), I received another error, this time the angle between the faces was X (something like 2 deg). I don't understand why, there should be no angle if they are parallel.
I tried to search for those problems and the only thing I found is that there might be a problem with the way solid parse the step file. I found download for talon in SolidWorks in the kit of parts in the following link: http://www.solidworks.com/sw/educati...gn-contest.htm
I tried to do the same, concentric the two pairs of holes, same problem. But at this model I could use parallel to lock the talon. I still don't like the result, i cant use concentric.

At first I used inch's and mm's in the same project and I thought that this is the problem but I tried the same with only mm's and still didn't manage to do that.

Does anyone had the same problem with the talons? How did you solve it?
It supposed to be one of the most basic stuffs.

Thank you for your help and your time

Re: SolidWorks - talon problem

You will come across this problem regularly when importing real parts. Often side walls aren't perpendicular to their bottom. This can help with injection molding.

I often just make sure the part's top, right, and front planes are placed in the correct places and then I mate to those.

Re: SolidWorks - talon problem

Mate the surface to the surface...but for the holes use a concentric mate - and choose only the circle of the hole's edge rather than the sidewall of the actual hole. This will like up the hole centers, and disregard any perpendicularity or "draft" in the hole.

Draft angle does not affect concentric Mates in Solidworks, so long as it was a round feature before it was drafted. Nor does draft angle affect measuring when you are in center-to-center mode (but it will affect min-distance mode).

Re: SolidWorks - talon problem

I think I understand what you're asking, but can you provide screen shots? You can use a site like imgur.com

Are you mating the bottom-most surface of the talon to your plate?
