General
Preconditions
• The drawings must contain information of a single floor of a property.
• There must be only one single space usage per space.
• A layer carrying the information for a net floor polyline is required to perform a successful import with CAD Import (and to create an ORJ file when the Create CAD Integrator file file is Yes).
• The scaling factor of blocks on supported drawings must be 1 - this is applies to all entities to be imported.
Limitations
• Planon only supports drawings with a building size less than 3,000 x 3,000 m (~ 10,000 x 10,000 ft). If parts of the drawing are outside of this area, they will be filtered out during CAD import. This is also true for block definitions with an origin outside this area.
• Only drawings saved in compatible AutoCAD versions and in .dwg format can be imported into Planon .
For information on which AutoCAD versions are supported by which Planon version, see Planon Supported Configurations.
• The drawings must contain their information in entities, such as polylines, blocks, block attributes, single/multi line text objects, or Connect for AutoCAD. These entities can exist in multiple layers or be present in drawings attached as Xref.
• Only data stored in the “Model space layout” can be imported.
Warning The following layer names are no longer supported:
• PLANON (used by Planon ProCenter Windows Client)
• Layers starting with: 'Planon mapping…'
• PLANON (used by Planon ProCenter Windows Client)
• Layers starting with: 'Planon mapping…'
• A drawing may only contain one net floor polyline and/or one gross floor polyline.
The net polyline should always fall within or coincide with the gross polyline. For non-StabiCAD drawings these floor polylines should be on different layers as well.Recommendations
• Each layer in an AutoCAD drawing can contain entities. Each entity has impact on the size and complexity of the drawing.
With regard to CAD Import and CAD Integrator the following applies: the fewer entities, the better.
A drawing with more than 15,000 entities may lead to serious performance problems and possibly to unworkable situations in CAD Import and CAD Integrator. Therefore, we recommend to restrict the number of entities to a maximum of 15,000.

• A polyline can represent a Space, Floor,or Workspace. It is recommended that you draw closed polylines in a such way that a single polyline is not used in two objects at the same time.
For example, a single polyline should not be used to draw the boundary of both Space-1 and Space-2. Each space should have its own polylines.
Additional
• Entities on frozen layers (which as a result are not visible in AutoCAD) are imported and will be converted into the CAD Integrator drawing (ORJ).
• It is not recommended to import old drawings while more recent drawings have already been imported as this may, in some cases, lead to different data.
For example, if during an import, a space is ended because its polyline is no longer in the drawing, importing the same drawing on an earlier date will not end the space on the earlier import date.
• It is not recommended to copy a polyline of a space or a workspace that is already imported in Planon because the metadata will be written back to the CAD objects resulting in an incorrect import of the drawing. If this has already happened, use EOS-CAD tools to delete the old Planon data.
• If a block is explicitly made invisible in the AutoCAD drawing, the block is not imported into Planon .
• The AUDIT command in AutoCAD is not supported, as the AUDIT command can corrupt the drawing. To clean the drawing, use the PURGE command.
