    Default Problem about assembly

    Hi everyone , i am new catia user. As you see i want to draw this (its V type cement trailer ) Normally i am using solidwroks. I draw this part by part beacuse
    we have plasma cut and i place on sheet metal. I drew all of parts on catia but cant assembly, i dont get it why it happening.

    You have to add assembly Constraints to position all the parts together. (just like adding Mates in SolidWorks)

    First, right-click on one of the parts and choose Fix to lock it's position.

    Then use the different types of Constraints (Coincidence, Contact, etc) from the menu on the right side to mate the other parts relative to the fixed part. You might want to use the online Help to learn about them.

    lots of options here:

    Instead of Contact constraint, you can use a Coincidence constraint. Or, an Offset constraint with distance = 0.

    If the mouth surfaces are not planar, you might be able to use the axis planes to constrain to.
