Hi all,
I don't know if this is common knowledge when editing 3D, but you can creates scaffolding to allow you to move the CCS more easily and place parts where you want. This is critical if you don't want to keep using features like move, which while precise, are a pain in the butt.
So the easiest way to get your parts placed correctly is with a little scaffolding.
Scaffolding is just a 3D part you create, with specific known dimensions, so that is exists in the model-space and either intersects it at different locations, or provides an external reference point to move the CCS origin to.
Here's an example. Suppose I want a 20mm long, 10mm diameter cylinger, with a 5mm hole all the way through the side, with it's center about 5mm down from the top.
Clearly guidelines are useless for this. It's not really central is it, so centers aren't much help either.
Creating a temporary scaffold to locate the CCS origin is the only way to do it without having to use tools like MOVE and ALIGN, and may be necessary even to use ALIGN properly.
Here's how it works. Let's start with a cylinder.
