Stretch the part
1.
2.
Click File > Open to load Block2.pk2.
* 
Problems with the file: If the file you download has a .zip extension, you will not be able to load it in Creo Elements/Direct Modeling until you change the file extension to .pk2. For example, you should change Stereo.zip to Stereo.pk2.
If you receive a warning that you have too many parts, you may have other parts loaded. Don't worry about it for this project.
3.
Select the lowermost edge of the vertical (side) face and click on the Command Mini Toolbar (CMT) to create a linear distance dimension (annotation). The dimension shows the width of the selected edge (100 units).
