Analyzing Light Distances between Two Sets of Elements

This task shows how to analyze the light distance between any two geometric elements, or between two sets of elements.

  1. Select a curve.
 

  1. Click Light Distance Analysis in the Analysis toolbar.
 

The Distance Analysis dialog box appears, the First set state is selected:
     
 
When editing a Distance Analysis feature that has been created with the former Distance Analysis command, the dialog box that opens is the former command’s one. 
 

The Distance dialog box displays the following options:

  • Projection Space: Defines the pre-processing of the input elements used for the computation.

    • No Projection of Elements: Elements are not modified and the computation is done between the initial elements.

    • Projection in X direction: The projection is done along the X-axis. The computation is done between the projections of selected elements. This option is available only for analyzing distances between curves.

    • Projection in Y direction: The projection is done along the Y-axis. The computation is done between the projections of selected elements. This option is available only for analyzing distances between curves.

    • Projection in Z direction: The projection is done along the Z-axis. The computation is done between the projections of selected elements. This option is available only for analyzing the distances between curves.

    • Projection in compass direction: The projection according to the current orientation of the compass. The computation is done between the projection of selected elements.

  • Options: Defines the display options.

    • Limited color range: Makes a simplified analysis, with only three values and four colors, display by default.

  1. Select the surface and move the pointer over the discretized element.

  1. Select Limited color range .
 

The Distance.1 dialog box displays the Limited color range and identifies the maximum and minimum values for the analysis.
     
 

  1. Click OK to exit the analysis while retaining it. 

The analysis (identified as Distance Analysis.x) is added to the tree under the Free Form Analysis.1 node. .
