CAD import definitions
For detailed information about CAD Import definitions, refer to the WebHelp.The following settings are important to have a seamless import based on the linked drawing and the linked Drawing Definition.
When creating a CAD import definition follow the print screen with the correct settings. Below the print screen you will find some references of certain fields that are specific to the customer, such as file name, etc.
• Create CAD metadata file? Set this to Yes. It will create an additional CAD Drawing that holds the UUID “Shared ID” which can be used for unique reference to sensor ID’s.
• File name wildcard filter: this is up to the customer to define, but normally you can use the name of the drawing.
• Allow Auto-correction? To successfully run a CAD Import it is important that the drawings to be imported fulfill the proper requirements.
In order to check this, it is possible to run a CAD drawing verification. The result of this process is a log containing instructions to manually correct a drawing.
Manually correcting issues can be tedious and error prone. Sometimes it is also possible to automatically correct these issues while doing a verification.
This is how it works:
1. On your CAD import definition, set the field Allow auto-correction? to Yes. The status of this field (Yes or No) will be logged.
Before the drawing is auto corrected, it is first backed up.
The location of the drawing backup is specified in System settings > File locations > CAD Import auto-correction backups. Here, you can retrieve the original drawings immediately after the CAD verification process. The backup location will also be shown in the validation log.
While importing the CAD drawing, the verification process is triggered. This process is set up so that the correction and verification are handled in sequence. This allows for logging elements that could not be resolved automatically.
2. All elements that were corrected are logged (together with their AutoCAD handle ID).
Reducing drawing entities
To prevent blocking the CAD Import server in the Cloud, a maximum of entities for drawings has been implemented.
Importing CAD drawings has been restricted to a maximum of 300.000 entities.
To reduce the complexity and number of drawing entities, the Planon application can automatically reduce the number of entities by joining polylines. By doing so, multiple polylines will be reduced to one.
Process
1. During verification, if the number of entities exceeds 15.000, the joining process is started.
2. If, after joining, the drawing entities exceeds 300.000 entities, the user will be prompted to manually reduce the entities in the drawing (error in the verification log).
If the number of entities in a drawing exceeds 15.000 but is less than 300.000, a warning message is given in the verification log.
To assist in identifying the problem areas, the log lists the layers and blocks and their corresponding number of entities.

Mapping between drawing & floor
With this tab and fields, you will be able to select the correct drawing that is going to be imported and linked to the correct property and floor (of that building):
Run CAD import
When CAD Drawing definition is created and linked to the created CAD import Definition. You can run verification first and when all is fine run the CAD import by clicking Run CAD import.
Check the logs and finally check the spaces in TSI Spaces. Check the result in the CAD Integrator view by selecting a space and viewing it in CAD Integrator. Check view on Workplace Insights > General. The drawings should appear when selecting the floor:
