[Solved] Need some direction on assembling parts from STEP files
Hi
New FreeCAD user. I apologize if this is obvious but I have spend the last week watching countless YouTube videos and reading forum but for the life of me I can't figure out the answer.
I'm running FreCAD 0.20.1 29410 Windows version.
I'm trying to build a custom enclosure for a HP EliteDesk G2 motherboard. As I'm learning FreeCAD, the best way to do it seems to have a model of the motherboard first. For that reason, I'm starting to model the motherboard. There is nothing ready-made in GrabCAD, so I'm building my own. The way I'm approaching this is to design the PCB and put on the the ports, USB, Ethernet, etc. The motherboard design just need to accurately capture the ports and holes in the motherboard.
Because I don't want to design from scratch every port, I got from GrabCAD some STEP files for other motherboard design and my plan is to build my PCB and put in the right place and height the various parts I'm getting from the step file.
My problem is that I can't find a way to put these parts with precision, X, Y, Z on the PCB board I'm designing. I can use transformation, to move the parts but that seems to be more eyeballing as oppose to being precise. All the examples I have seen on YouTube with assembly, talk to matching surfaces, but for example, my USB port sits 7 mm on top of the board, 14 mm from the right edge, and 2 mm in front of the edge of the board. How do I place these parts with previsions relative to the edges of the board?
I have attached my project file. Can someone point me in the right direction? Thanks Chasin

Hi and welcome to the forum!
First thing to do is to learn about Attachments. The Basic Attachment Tutorial will help here. Then you can offset from the attachments origin by changing the AttachmentOffset, either with the Placement dialog, or directly by changing the properties in the Data tab at the lower left side.

A Sketcher Lecture with in-depth information is available in English, auf Deutsch, en français, en español.

Std_TransformManip for idea

Re: Need some direction on assembling parts from STEP files
Thank you very much Thomas for making the video specific to this. I have been playing it as .25 speed to try and follow and understand the steps so it may take me a day or two to get the hang of it.thomas-neemann wrote: ↑Sat Oct 01, 2022 6:38 am

Re: Need some direction on assembling parts from STEP files
Just to close up this topic. Thanks again for all the help. I tried both ways, but at the end I used Manipulator workbench. It was easier to user for a novice like me.
