Have just started using SH3 to help a local sports club design a new layout for its' facility, and must say it is brilliant.

However I am using a free equipment library issued by a sports equipment company, and it is missing a couple of pieces of equipment, that the company don't want to add as they are not "currently supplied", but are almost identical to one of the pieces that is included.

The SH3F file opens with 7Zip and it looks the missing equipment just needs minor changes to the PNG and adding with new names (dimensions are the same as the existing equipment).

However there are also OBJ files I know nothing about!

Is this something I can do, and if so how?

Many thanks
