Step for moving parts

[N. W. Perry]

Does anyone know if LDraw allows to create step for moving some parts (instead of adding)? 

For a complex model, it is very common to add a part (like a pin) to a component, then push it in when connecting to another component. But I haven't found a way to make such instruction in LDraw. 

Thanks!

There are a couple of solutions for this, none of which is 100% ideal. The most widely used is buffer exchange, a set of metas from MLCad that's also understood by LPub and LDCad. LPub also has a new feature called Build Mod[ification], which is supposed to update this process but I think isn't fully implemented yet.

Documentation for these features isn't great—the best way to learn about them may be to search this forum.
