LinkProfileControlled

This subassembly is a general purpose utility to add a surface link by specifying a profile elevation to define the slope and/or the width.

A negative rise:run slope value can be used for the Slope parameter. Negative slopes go downward in the direction inserted. The Width parameter does not allow a negative value. When a negative or zero width is assigned to the Width parameter or Width target, the value is set to 0.01.

Three different methods to create a variable width and slope can be used when building a corridor model.

• A separate profile elevation can be assigned to represent the slope and/or the width.
• Subassembly properties can be set.

• A horizontal target can be used to assign the width and a vertical target the elevation.

A combination of a parameter, target and a profile controlled can be used.

The link is added on the side of insertion starting at the attachment point and extending the given width and slope in the side direction. If a Width from profile target is assigned a profile during corridor building, the width of the link will vary to match the elevation of the profile. If a Slope from profile target is assigned a profile during corridor building, the slope of the link will vary to match the elevation of the profile.

If an offset horizontal alignment is assigned to the Width target during corridor modeling, the width of the link will vary to match the offset of the alignment. If a profile is assigned to the Elevation target, the slope is adjusted to match the profile elevation at the end of the link.

Target Priority

The default width of the subassembly is determined by the Width parameter. Both target options take precedence over the Width parameter. When assigning targets, a Width target will take priority over a Width from profile target, if both are assigned.

The default slope of the subassembly is determined by the Slope parameter. Both target options take precedence over the Slope parameter. When assigning targets, a Slope target will take priority over a Slope from profile target, if both are assigned.

The attachment point is at the inside edge of the link. This subassembly can be inserted in the left or right direction from the attachment point. The attachment direction constrains the width and slope direction.

Info: All dimensions are in feet unless otherwise noted. All slopes are indicated as a percent slope with a "%" sign.

This section lists the parameters in this subassembly that can be mapped to one or more target objects, such as a surface, alignment, or profile object in a drawing.
