BREAKLINE (Express Tool)

Creates a breakline, a polyline that includes the breakline symbol.

Find

You specify two points and the location of the breakline symbol between them. You can control the relative size and appearance of the breakline symbol and the extension of the polyline beyond the selected start and end points.

Note: The current setting of the DIMSCALE System Variable controls the ultimate size of the breakline elements. For example, using the default breakline block, BRKLINE.DWG, with a distance of 1.00 between defpoints, and assuming a BREAKLINE Size option of 0.5, with DIMSCALE set to 48 the resultant distance between defpoints is (1 * 0.5 * 48) or 24 units. This relationship between the BREAKLINE elements and the current DIMSCALE setting is consistent with the behavior of standard AutoCAD dimension scaling.

Options

Block Determines the block to be used as the breakline symbol. The default block is defined by brkline.dwg.
Size Determines the size of the breakline symbol.
Extension Determines the length of the line extension beyond selected points.

Customize the Breakline Symbol

You can create your own block for the breakline symbol by creating a drawing in the AutoCAD Express folder. Make sure that the drawing contains two point objects that have been created on the Defpoints layer. Those point objects determine the placement of the symbol and how the line will be broken. Here are the steps:

  1. Start a new drawing.
  2. Draw the breakline symbol:

  3. Make the Defpoints layer current. If it does not exist, create it and make it the current layer:

  4. Use the POINT command to create a point object at each location where the line will connect with the breakline symbol. Use only two points.

  5. Save the drawing file in the Express folder of the AutoCAD installation folder, for example C:\Program Files\Autodesk\AutoCAD 2014\Express.

When you start the BREAKLINE command, use the Block option to specify the drawing file for the new breakline block.
