Screw Mate and Assy Qty. Question

Screw Mate and Assy Qty. Question

Screw Mate and Assy Qty. Question

(OP)
I have a couple of questions.

1. I don't have the toolbox add-on so all my parts were imported from elsewhere or custom made. From my design library when I insert my flat head screws into a countersink the coincident mate always is upside down (the screw is sticking up rather than into the plate). After I insert them I have to then go back thru and reverse the coincident mate for each and every screw. How do I fix it so the flat head screws mate correctly with the countersink when I insert them in an assembly?

2. How do I change the qty of a part at the assembly level for a drawing BOM table so that I don't have to break the parametric link by simply over riding the qty value directly in the BOM table? An example: lets say I have a standard spring that is a common part (so I don't want to mess with the individual part file) and there are 1000 springs of type A and 500 of type B in a particular assembly. But I don't want to insert or show 1500 springs in the assembly, at the assembly file level how can I make 1 spring represent 1000 springs, and another spring represent 500 springs for the drawing BOM table?

RE: Screw Mate and Assy Qty. Question

1) Use the conical faces in the mate. This should force the correct alignemnt.

2) Create configs of the springs. In each config create a "Unit of Measure" property and enter a value. (Config 1 = 1, Config 2 = 100, etc). The UoM property can then be read into a BOM column.

RE: Screw Mate and Assy Qty. Question

2) Create a config of the spring that has no geometry, insert that configuration into the assembly and create a linear pattern with the required number of instances.  I do not know the degree to which this approach would degrade performance of the assembly, but it does eliminate having to modify the part file when you want to change how many instances are in an assembly.
