Im finding it difficult to assemble the two parts (attached) such that they exactly fit into each other. Can somebody help me assemble these parts. Part 1 is the male part which has to fit into the female half (part 2).
The answer to simple mating on a part like this...
Model both parts symmetrical, so the first sketch is on the origin.
Then when bringing the parts into the assembly, use the planes in each part to mate.
