Creality Print v5.1 [Add Part, Add Negative Part, Add Modifier...etc.]

Hello,

Noob here, still learning the Creality Print software and have a question. I can’t find any documentation that goes over Add Part, Add Negative Part, Add Modifier features of the software. Anyone know where I can find the documentation?

My use case is this, I have a model with open pin joints and a separate model for the pin. I want to add the pins to the main model but when I do, I get a warning saying they’re too close together. What’s the solution?

I must admit to not how to it in Creality Print but I know you can do the split and dowel pin in Prusa slicer, give that a go and see if you can get that to work.
