      Note: If you choose to clear the checkbox, you will need to manually select each arc from the beginning of the pipe to its end. During selection, if a mistake is made, you will need to restart the selection process. However, manual selection can be useful when you want to measure only a portion of the tube.

   2. Lock tool - Select to use the command more than once.
   3. Hyperlink - Enter a link to a file or to a document and user view within the current file.

   2. Double-click to accept the measurement and see the markup label. 
5. Position the markup, then click once. The highlighted line changes color to indicate that the measurement is complete.
   
6. At this point, you have the following options:
   1. Click Copy to copy the markup content to the Windows clipboard.
   2. Click Export... to save the markup content to a .csv file. (See also Create a tube length bill of materials on this page.)
   3. Click Stop when you're finished taking multiple measurements.
   4. Click Close (or X) to end the command and close the dialog box.

The Tube Length Bill of Materials command exports a model's existing tube length measurements After completing a tube length measurement (see Measure tube length on this page), you can create a bill of materials by exporting the results to a .csv file. A bill of materials contains the following information:

• Length

• Diameter 

• Arc1 Center XYZ 

• Arc2 Center XYZ 

• BendRadius 

• BendAngleDegrees 

• BendCenter XYZ 

• Intersection XYZ 

• Total length
