These custom tests are used with orthographic view styles for outfitting drawings and drawings by rule styles for scantling drawings.

Primary Orientation

Displays the orientation of the primary linear axis of an object with respect to the drawing view. The primary linear axis is along the x-axis of the local coordinate system.

Secondary Orientation

Displays the orientation of the secondary linear axis of an object with respect to the drawing view. The secondary linear axis is along the y-axis of the local coordinate system. For members, this corresponds to the web orientation.

Primary Orientation and Secondary Orientation use the same options to display the model with respect to the drawing view.

The options that specify a direction (for example, Normal, toward you) are specialized orientations. They are most commonly used for steel members and pipes that have an air or liquid flow.

Normal

  • Normal, toward you

  • Normal, away from you

Sloped

  • Sloped, toward you

  • Sloped, away from you

  • Sloped, projects horizontal

  • Sloped, projects vertical

The example below, from left to right, shows pipes with the orientations Sloped, projects horizontal, Sloped, projects vertical, and Sloped.

The Sloped, projects horizontal and Sloped, projects vertical options provide special orientations for situations in which the drawing needs to distinguish between a sloped pipe or member that projects orthogonally on the sheet and those that project non-orthogonally on the sheet. For example, you may prefer orthogonally-projected pipe be dimensioned in the drawing with the pipes that are parallel and orthogonal to the sheet. The following graphic shows examples of a 3D model with pipe for both cases:

1

This pipe is sloped in the 3D space of the model, but projects using the Sloped, projects horizontal primary orientation. The view style specifies that the dimensions for the pipe are handled the same as the actual parallel, horizontal, and vertical pipe in the view.

2

This pipe is sloped in the 3D space of the model, but uses the Sloped primary orientation and does not project horizontally or vertically. The view style distinguishes between this pipe and pipe 1.

3

These pipes are parallel and horizontal or vertical to the view, and use the Parallel, horizontal and Parallel, vertical primary orientations.

Parallel

  • Parallel, vertical

    • Parallel, pointing up

    • Parallel, pointing down

  • Parallel, horizontal

    • Parallel, pointing right

    • Parallel, pointing left

  • Parallel, sloped

The following graphic shows an example for members:

1

This target member has a primary orientation of Parallel, vertical and a secondary orientation of Parallel, horizontal.

2

This non-target member has a primary orientation of Normal, toward you and a secondary orientation of Parallel, horizontal.

For dimensioning purposes in the drawing view, the Parallel, horizontal and Sloped, projects horizontal pipes are part of the same dimensioning chain. The Sloped pipe is not included in the dimensioning.

You can resymbolize the model graphics based on special orientation cases. For example, you might want to represent piping items that are parallel to the sheet plane as single lines, while representing the items coming straight out of the sheet as special symbols.
