The model used in this example contains roof beams and purlins.
Measure the slope angle of the beam, then rotate the purlin by this angle:
- To measure the slope angle, use the Ctrl + G
shortcut, and then select three points in the model that describe the measured area. In our example, the measured angle is 45 degrees.
- Modify the purlin orientation angle to 45 degrees in its properties window.
Rotate the purlin using a user defined reference point. This method is best when the beams are sloped at different angles.
- Define the reference point at one of the beam's ends (in this case, at the upper end). The created point is automatically numbered with "1" (if it is the first point created in the model).
- Select the purlin. Enter the point ID in its properties window as shown below, to define the purlin orientation by point. The purlin's y-axis will slope towards the specified point.
- Modify the purlin orientation angle.
The beams and the purlins are now correctly positioned.
