Parallel line segments

Module(s): Advanced Draft + Site Plan

To draw lines parallel to an entire element

1. Click Parallel Line Segments (How) or Parallel Line Segments (How).
   

   Activate Parallel Line Segments in one of the following ways

   • Menu bar: Create Terrain Site Plan

   • Palette: Tools Create area in the following module(s):

   Site plan

   • Configuration: Landscaping/Urban Planning Site Plan flyout
   

   Activate Parallel Line Segments in one of the following ways

   • Menu bar: Create Advanced Draft

   • Palette: Tools Create area in the following module(s):

   Advanced Draft

   • Configuration: Landscaping/Urban Planning Advanced Draft flyout
2. Click the reference element for the parallel lines.
3. To create a line parallel to an ellipse, specify the mode for creating lines parallel to ellipses in the Input Options. For all the other elements, click Selected element in its entirety in the Input Options.
4. Enter the offset between the parallel lines in one of the following ways:
   • Click in the workspace to define a point through which they are to pass.
   • Enter a numerical value for the offset in the dialog line, click in the workspace to specify on which side the parallel lines are to be created and enter the desired number of parallel lines in the dialog line.

To draw lines parallel to segments of an element

1. Click Parallel Line Segments (How) or Parallel Line Segments (How).
2. Click the reference element for the parallel lines.

   Note: You cannot create lines that are parallel to segments of ellipses: Allplan always uses the entire element.

3. Click Part of selected element in the Input Options.
4. Enter the offset between the parallel lines in one of the following ways:
   • Click in the workspace to define a point through which they are to pass.
   • Enter a numerical value for the offset in the dialog line.
5. Define the area for the parallel lines in the following way:
   • Enter the initial point or initial station.
   • Enter the end point or end station.

     Note: If the points you placed are not on the element, the program drops a perpendicular between them and the element.

6. Click in the workspace to specify on which side the parallel lines are to be created and enter the desired number of parallel lines in the dialog line provided that you have entered a numerical value for the distance.
   

Notes:

• You can enter a positive or negative offset. When you enter a negative offset, the parallel lines are created in the opposite direction.
• For composite elements, the segment clicked is used as the reference element when you specify the side on which the parallel lines are to be created.
• In the case of freehand lines, the geometry may make it impossible to draw parallel lines beyond a certain distance. In the case of splines, parallel lines can only be approximated as it is mathematically impossible to create exact parallels. To optimize the result, control points are added to the splines.
