Repositioning 3D Models in eCADSTAR

When incorporating 3D models into your footprint, the CAD models may have different origin points. Here’s a quick method to reposition and align them accurately.

Aligning the 3D model by setting the coordinates

This method demonstrates how to align a 3D model with your eCADSTAR footprint by setting precise XYZ coordinates.

Initial import steps:

1. Load the library to eCADSTAR. Follow the import steps here

2. Open the footprint:

• Click File > Open Library > Select Library path > Search for the imported part > Right click over the selected part > Edit footprint

Steps to align the 3D model:

1. Select the 3D Model tab > switch to 3D View

2. If the model is below or above the PCB surface:

• Select Move > Coordinates > set Z value to the proper sitting plane > Execute

3. To set the orientation to 0° against the PCB top surface:

• Select Move > rotate using Angles > click Execute

4. Repeat the previous step if necessary

5. Use the Preset View to check the bottom view and ensure leads are aligned with the holes/pads

6. Continue to adjust the coordinates until the 3D model and the footprint is properly aligned

• Select Move > Coordinates > adjust the X,Y,Z coordinates > Execute

7. Use Preset View again to confirm alignment from different views
