SettingDescription
Analyze Type Here, you determine how to define the final local areas from the analysis.
  • Main Direction – Only the analyzed main direction of dimensioning is used to build an area.
  • Transversal Direction – Only the analyzed transversal direction of dimensioning is used to build an area.
  • Overlay Singles – New areas are built by overlaying the areas of the analyzed main and transversal direction.
  • Overlay Groups – New areas are built by overlaying the areas of the analyzed main and transversal direction. Then, bordering areas are new combined.
Min. Count The minimum number of direction-determining shapes which must exist when comparing the length classes in one direction to decide which is the main direction of dimensioning.
Threshold (%) The relative difference in length with regard to the longest shape of a higher class to permit building of a new lower class
Min. Length The minimum length of the shape to be used for analysis at all
Max. Distance The maximum distance of one shape end to the other to be connected to an imaginary continuous shape.
Max. Offset The maximum offset of the center axes of two parallel shapes to be connected to an imaginary continuous shape.
Max. Distance to Border horizontally If the distance to the next bordering edge in analysis direction is smaller than this value, the previous area in this direction will be extended up to the new border.
Max. Distance to Border vertically If the distance to the next bordering edge transversal to the current analysis direction is smaller than this value, the previous area in this direction will be extended up to the new border.
Max. Width to Combine Width a section (disk) at least has to have in analysis direction to be processed as separate area. Otherwise, the previous area will be extended perpendicularly completely up to each of these borders if the width is also bigger than the value brought into line.  Available for Overlay groups analyze types.
Max. Distance for Collect Maximum distance between two areas which came into being by overlaying to be collected again to a common area.
Min. Number of Border Shapes This number of direction-determining shapes of high classes has to be used at least for building the borders of the area. Otherwise, the shapes of the next lower class will be used as well.
Min. Total Size Minimum length and width of a new area by overlaying. Smaller areas are assigned to the previous neighboring area. Available for Overlay analyze types.

Method of Analysis

The analysis of local areas is done by cutting the whole view by a series of sections. These sections are limited to those shapes which appear as continuous shapes in the view.

The resulting (hypothetical) shape segments are classified according to their length and—starting with the longest segment—the direction of each shape. These are compared to determine the direction in which the majority of the segments lie. This then determines the cutting direction and, thus, the main direction dimensioning (perpendicular to the cutting direction).

Now the sections are collected in the analysis direction by the predefined minimum widths. The final area size is limited by the shapes which are transverse to the cutting direction. Finally, the extents (bordering edges) are determined.

An overlay can be used to create new areas out of the intersection of the main (cutting) and transverse directions. A collection of segments and alignment can be done (however, only in the cutting direction). Thus, void or empty areas (such as notches/ copes) can be best accounted for.

Note: Unfortunately, there is no general solution with fixed parameters which can be used for all kinds of constructions. Therefore, it is inevitable that you will need experiment with the parameters—especially in case of complex constructions—until a favorable division is reached.
