Misalignment issues between 3D packaging and planar packaging

[If you don't understand, ask] The previous post said that the mismatch between 3D package and 2D can be solved by changing the XYZ angle of the 3D model https://en.eeworld.com/bbs/forum ... 1&page=1#pid2863561 At this time, the position of the previous post is now as shown in Figure 1. For the same pin, the pin center of the 3D model package does not seem to coincide with the pin hole of the flat package. There is a deviation. How to adjust this? Just like Figure 2, add a center point capture point to the 3D model, and put the 3D model package into the 2D package. There is no deviation. Figure 1 Figure 2

After pressing TAB, the dialog box for modifying XYZ values will appear. This large green cross is the origin of the 3D model, similar to the (0,0) point of the PCB package. Now I want to make a pin of my 3D model also this origin so that it can coincide with the origin of the 2D package (the white cross). I don't know how to set it.

The 3D model has its own origin. After alignment, you also need to adjust the X/Y/Z axis angle and installation height of the 3D model.

I figured it out. It took me a while to figure it out. Thank you.
