Creating pattern lines

Module(s): Advanced Draft + Site Plan

You can use the Create Pattern Line tool to resize a pattern line between individual lines, polylines, splines or composite elements. The pattern line’s pen and color are adopted from the element. You can also modify existing pattern lines.

To create a pattern line between two elements

1. Click Create Pattern Line (How).
   

   Activate Create Pattern Line, Slope in one of the following ways

   • Menu bar: Create Advanced Draft

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

   Advanced Draft

   Site Plan

   • Configuration: Landscaping/Urban Planning Advanced Draft flyout
2. Click New in the input options.
3. Click the (composite) element or polyline (in the active file) which serves as the top of the slope.
4. For composite elements, specify from which element and to which element the pattern line is to stretch. Click the right mouse button to select the entire composite element.
5. Click the element at the base of the slope or enter a polyline that is to form the base of the slope.

   When selecting this element, make sure that you do not click it near to an end point or a control point. In this case, the pattern line would be based on the point clicked and not on the element. You can easily tell whether you have selected the element: it is displayed in the selection color.

6. Set the parameters of the pattern line.

Notes:

• The direction of the pattern line to be created is detected automatically based on the top and base of the slope.
• If you delete the base of the slope, the slope reverts to the original element. In this case, the pattern line is applied to the element.
• If you move the top or the base of the slope, the slope adapts to the change associatively.

To modify existing slopes

1. Click Create Pattern Line (How).
2. Click Modify in the input options.
3. Click the slope.
4. Set the parameters of the pattern line.

Note: To return a pattern line to the original element, choose Off.

Centered + not mirrored (C) or left + not mirrored (L)

Troubleshooting

1. The hatching is not visible on the screen:
   Inadequate slope base —› replace it
2. Slope intersection does not work cleanly:
   Increase the pattern division value.
   Check whether you have set a suitable pattern width.
3. When I zoom, the hatching is not drawn in full:
   Change the slope, increase the pattern height (the width will change automatically). Then, reset the width of the pattern to its previous value.
4. In addition to the slope, normal pattern lines appear on the opposite side:
   This indicates that there are several intersections and that only one of them is being used as a slope.
