Exercise: Move to the Coordinate System (CS) of a 3D model

This file contains two meshes Theoretical Dam (bad CS) and Theoretical Dam (good CS). Select and show only the mesh Theoretical Dam (bad CS) (you will probably need to type A to make a Zoom All). Then press X, Y or Z. You can see that the axes of the coordinate system are not coherent with the mesh. Now select and show only the other mesh Theoretical Dam (good CS). Press again X, Y or Z. Now the axes are coherent.

Show only the mesh Theoretical Dam (bad CS), select it and go to Geometric Registration.

Move to the coordinate system of the dam

You have to respect an order when using the command. So first, click and use the option Vertex / End to place the Source point on the bottom left corner of the dam. A new dashed coordinate system will appear where you have clicked the point (see above). Keep (0, 0, 0) for Destination point as we want to have the bottom left corner of the dam as the origin of the new frame.

Then, change the Main axis direction. Choose Z, and click to define the new Z axis. For example, use and click 2 points on a vertical edge.

Finally, define the Second axis direction in a similar way by choosing Y and clicking on . For example, use and click 2 points on a horizontal edge.

You can now click OK. Press A to do a zoom all, and then X, Y or Z on the keyboard. You will see that all the axes are now coherent with the model.
