Spiral beams in drawings
Spiral beams can be show in drawings either folded or unfolded. In unfolded views, spiral beam is unfolded straight.
For details about creating concrete and steel spiral beams, see Create a concrete spiral beam and Create a steel spiral beam.
In the example below, the Unfolded option is set to Yes and in view properties on the Attributes 2 tab. Note that the part is cut in the view.
In the following example, the Unfolded option is set to No.
Dimension spiral beams
You can add straight dimensions, angle dimensions and radius dimensions to spiral beams.
In the following, the automatic creation of dimensions is explained. You can also create dimensions in spiral beams in an existing drawing in view level properties.
Spiral beam part marks
You can show the rotation of the spiral beam in part marks. The rotation angle is defined in the spiral beam properties in the model.
-
You can add part marks to spiral beams in the same way as for other parts using one of the following ways:
-
In an open drawing, select a spiral beam, right-click and select Add mark and then select Using applied mark properties to use the current mark properties, or Using view properties to use view level mark properties.
-
In an open drawing, select a spiral beam, and on the Annotations tab, click Part mark and select For selected parts.
-
You can also define automatic marks in drawing properties before creating the drawing.
