Last updated: 2021-02-12

This subassembly inserts a single link, where the attachment point can be specified at the endpoint of another link in the assembly OR the endpoint of a target surface.

Link is defined by a Slope and one of the following:

  1. Intersection of a surface
  2. Distance measured from the baseline alignment
  3. An Elevation

  4. Distance measured from attachment point

Link is extended outward from attachment point. Offset targets can also be used to define the distance and elevation parameters.

Subassembly inserts a single link, where the attachment point can be specified at the endpoint of another link in the assembly OR the endpoint of a surface. The Attachment Point Type parameter determines the method to use.If the endpoint of a surface method is selected, the Surface to Extend target must be set or no link is inserted. If the Attachment Point Type is Surface, the subassembly attaches at the leftmost or rightmost offset of Surface to Extend (insertion side dependent).Can be inserted on either the right or left side. Regardless of the Attachement Point Type method,the user will still specify a point on the assembly in order to add the subassembly.

Once the attachment point location has been determined, the link is then inserted outward from this point using the slope parameter until it reaches the ‘target'.The target can be specified as an offset from baseline, a distance from the insertion point, an elevation, or a surface.Only one target can be used.

The attachment point is at the beginning of the link. The direction of the link is determined by the side.

In layout mode the subassembly displays the link at the given slope for a horizontal distance of 10 feet.

Info: All dimensions are in feet unless otherwise noted. All slopes are in run-over-rise form (for example, 4:1) unless indicated as a percent slope with a "%" sign.

Parameter Description Type Default
Side Specifies which side to place the subassembly. If Side = Left, SA is drawn on the left side of attachment point; If Side = Right, SA is drawn on the right side of attachment point. Left / Right Right
Attachment Point Type Specifies where the attachment point of the link is. Choices are to begin the link at the endpoint of another link in the assembly OR the endpoint of a target surface.

String, Combo List of options:

a.) Value,

b.) Vertical,

c.)Horizontal

Link
Slope Type Method of obtaining the slope of the link. Upward Vertical means the slope direction is upward; Downword Vertical means the slope direction is downward.

String, Combo List of options:

a.) Value,

b.) Vertical,

c.)Horizontal

Value
Slope Value Slope of the link when Slope Type is set to Value. Negative slopes go downward in the direction inserted. Slope -4:1
Target Type Specifies the target of the link.

String, Combo List of options:

a.) Surface,

b.) Offset,

c.)Relative Elevation,

d.)Absolute Elevation

e) Distance

Offset
Offset Target Value Offset of the end of the link. A negative value indicates an offset to the left of the center baseline (not offset baseline), while a positive offset is to the right of center baseline. Numeric 50
Elevation Target Value Elevation at the end of the link. Numeric 900
Distance Target Value Width of link from the insertion point to the end of the link. Numeric, positive 10

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.

Parameter Description Status
Surface to Extend Name of the surface being extended. The following object types can be used as targets for specifying this surface: surfaces. lorem ipsum
Surface Target Name of the surface to intercept. Only used when Target Type is set to Surface. The following object types can be used as targets for specifying this surface: surfaces. lorem ipsum
Offset Target Object used to define the offset location of the end point link. This offset must be outside the attachment point location. Only used when Target Type is set to Offset or Distance. The following objects can be used as targets for specifying this offset: alignments, polylines, feature lines, or survey figures. lorem ipsum
Elevation Target Object used to define the elevation of the end point of the link. Only used when Target Type is set to Elevation. The following objects can be used as targets for specifying this offset: profiles, 3D polylines, feature lines, or survey figures.
