Exercise: Convert a cloud from a unit to another

Open the file BestFitOnRef.3dr.

This file contains several clouds in meters and one in feet as well as a reference mesh in meters.

Show only the clouds named "Aligned Dam" and "Aligned Dam in ft" and press A to make a Zoom All.

Select both clouds, right click and select Properties. Have a look at the size of each cloud: one is roughly 3 times bigger than the other.

To do the conversion:

  1. Show only cloud in feet and select it, then go to Resize.

  2. Define the center (0, 0, 0).

  3. Then, select the option Same scale for X, Y and Z and enter 0.3048 (converting feet to meters requires a multiplication by 0.3048).

  4. Press OK.

Have a second look at the properties: the size is now exactly the same.
