Example of Ladder Definition

 

Note: A ladder has been defined in the 3D frame presented in the drawing below.

To define a ladder:

1. Define a 3D frame as displayed in the drawing above.
2. Click the option Ladder .
3. In the drawing area, click to specify 3 points defining the ladder location (P1, P2, and P3 as shown above).
4. On the Position tab of the Ladders dialog, specify the ladder dimensions as shown below:
5. On the Vertical bars tab, specify parameters:
   • For Type of extended bars, select Direct.
   • For Profiles, select LP 3.5x3.5x0.25.
   • For Families, select Profile.

8. At the bottom of the dialog, specify bolt parameters:
   • Bolt diameter = 0.625
   • Grade = 4.8
9. Click Save as template (an additional dialog displays, in which the template name is specified, and the settings will be saved to an external file). After you reopen the dialog for ladder definition, this template will be available for use.
