Analyzing drawings
If your drawing consists of nested entities, use the Analyze drawing feature to make sure that the area calculation and hatching is correct for the nested entities.
Nested entities can be spaces, holes or constructional elements. They exist as space within a space or an excluded area in a space. Therefore, when calculating the area and hatching of spaces, all these type of nested entities are taken into account.
If you have applied a Space Norm during CAD Import, the threshold values as specified in that Space Norm will also be applied in Connect for AutoCAD.
Procedure
1. In the Context menu, point to Connect for AutoCAD and select Analyze drawing.
There are two ways to analyze a drawing:
◦ Manual analysis
◦ Automatic analysis
For Manual analysis select Analyze drawing. An information message box appears after completing the analysis.
2. For Automatic analysis in Settings, select General and select Automatically analyze drawing. This option automatically analyzes the drawing before saving.
 | If your drawing contains unclosed polylines that represent Spaces, Rent to units or Rent from units, then the outcome of area calculations, available workspace calculations and copying data from and to spaces might be incorrect. We recommend that your drawing only contains closed polylines. |
