Surface Slope Label

Tools to create, convert, import and export surface slope labels.

Keyboard Command: SurSlpLab

After executing this command, you will prompted to select a surface. Pick a surface in the drawing then you will be presented with the following options.

• Add: Adds slope labels at points along a selection set of objects.
• Convert: Convert nodal objects like CogoPoints, inserts, leader to slope labels. If the DELOBJ variable is set, the source objects are removed.

  For leader/mtext combos, the mtext object must be on the same layer as the leader. The distance from the leader midpoint to the mtext insertion point must be less than the mtext height.

• Export: Exports properties of selected slope labels to a DTZ (Data Table Zip) file (suitable for import).
• High: Adds elevation labels at the high points (steepest slope) of the surface (there may only be one).
• Import: Imports point coordinates and places slope labels at the specified locations. The slopes of the points in the file are ignored (the slope of the surface is used). When using DTZ files, the ½ point property along with the style previously used is restored (assuming the style name exists).
• Low: Adds elevation labels at the low points (flattest area) of the surface (there may only be one).
• Offset: Add slope labels along a selected linear object. Provide options for begin/ending stations, interval and left/right offsets.
• Report: Sends information about selected labels to Excel, Word, AutoCAD Table, and more.
• Style: Assign styles to a selection set of slope labels by designated ranges. The surface slope styles defined in the drawing control the ranges available. To create a surface slope style for consideration in this tool, simply put the minimum and maximum slopes separated by " to " as part of its name. Take these examples:
  • Percent (Original)
  • Percent 0.00 to 9.99
  • Percent 10.00 to 19.99
  • Percent 20.00 to 99.99

  In these examples the first item would not be applied since it neither has a pair of number nor the " to " spacer. Note that during processing all slope label values (precision value at that point, not the displayed text) are rounded to two decimal places to determine the category.

Notes:

• Before creating slope labels, the tool checks it's point list to make sure duplicates are not created from that list. It does not check existing labels to make sure one does not exist at that location.
