Performing CAD drawing verification
For a successful CAD Import, a CAD drawing must meet various conditions. Typically, an import of complicated drawings or multiple drawings can produce errors. In such cases, it is difficult to find which drawing and which layer is giving the error.
The majority of failed imports are due to Crossing polylines or overlapping Space entities (gross & net). These errors can be avoided by verifying a drawing before importing. CAD verification functionality enables you to inspect the entire drawing and locate where the faults are.
Currently, the CAD verification checks that:
• Polylines do not cross
• Drawing location
• Filter-text is used (for more simple reproduction)
• The Planon version is filled
• An entity is inside another entity
• Workspaces are inside the space
• Workspaces do not overlap other workspaces
• Fixed workspaces are surrounded by a space
• Fixed and flexible workspace are surrounded by a net space polyline
• There are no endless loops
◦ main drawing with an xref referring back to the main drawing
◦ block definition that refers to another block that refers back to the first one.
A critical error will be logged and the import process is stopped.
• The version of AutoCAD used for creating drawings is available and logs that in the CAD drawing verification log.
• Each gross floor polyline contains a net floor polyline.
• Dimensions are acceptable (for example: a floor with a width of less than 2 or more than 4500 meters is considered as a mistake).
• Verify the connection with the CAD Workbench server. If a connection cannot be established, a pop-up message is displayed and a log entry is created in the verification log.
• Elevation is auto corrected to 0 for xref layers such as spaces, workspaces.
• There are no missing, duplicate, or orphaned data entities. If so, a log entry will be created.
Procedure
1. Go to CAD import definitions > CAD import definitions.
2. Select the CAD import definition you want to verify.
3. On the action panel, click Perform CAD verification.
The process starts running in the background.
4. After completion, go to the Import logs step to see the verification results.
The event logs of the CAD verification are preceded with the text '[VERIFICATION]'. Any faulty drawings are preceded with an error icon ( 
). For detailed information of the fault, go to the Import log details step.
). For detailed information of the fault, go to the Import log details step.
• To understand the different crossing polylines listed in the Import log details, see Crossing polylines • To view the crossing polylines listed in the Import log details, open the AutoCAD drawing and use the EOS CAD tool to identify them by ussing the AutoCAD Handle ID. For more information, see .
