%(#000080)[New to this, but looking for some help on writing the formula for this task

I've got a drawer runner that changes its length (LenY) in relation to the drawer box, with all the screw holes etc staying in position and size.

What I am trying to achieve is that when the drawer runner exceeds 45cm in length, an addtional 6 screw holes appear fixed in place. Then, if the drawer runner is re sized to smaller than 45cm, they disappear again.

I've got a basic grasp of the multiples formula, but am struggling to apply this once past the required distance.

Any help would be appreciated

Cheers]

one method is to use the copy function once a certain criteria is obtained
however as you probably have already discovered making copies of DC holes is difficult. First you divide between front and back cutting planes, then you create a component of the inner raw geometry to build another component inside which we apply the copies formula and spacing distance too.

Attached is an example

If you post your model, can modify to suit your needs if this is not what you are after
