CADprofi layer standards

All CADprofi program objects are categorized in accordance with  Open BIM (IFC classification). In CADprofi program it is possible to enable automatic layer management. With automatic layer management enabled, objects from individual BIM classes are inserted on the appropriate layer that is specified in the layer standard. User can create new layer standards on his own and adapt them to his needs.

For most objects user can specify any name, color and other layer parameters. Exceptions are pipelines, ventilation ducts and electrical ducts and cable trays, which are closely related to types or systems (installation definitions).

In case of enabling the extended layer name most objects will be inserted on layers, that contain the corresponding suffix consistent with system or installation.

Dialog window contains:

 Choose BIM class from object – this button allows to indicate a specific object from the drawing. Afterwards the BIM (IFC) class will be retrieved from the selected object and placed in the dialog window.

 Export layer standard – this button allows to save the current layer standard to a file..

 Import layer standard – this button allows to import settings from *.stdlay files to the current standard with the possibility to overwrite the existing settings.

BIM classes and layers from standard – list of available BIM classes.

IFC class name – name according to the IFC (Open BIM) standard.

Internal class name – classes that introduce a more detailed division of objects.

Objects layer for selected class – this field displays the layer name of the currently selected class.

Set layer for the selected BIM class – selection field that allows to assign a layer name to a selected class.

Define new layer  – addition of a new layer to a list.

Remove selected layer from standard  - deletes the indicated layer from the list. It is not possible to remove standard CADprofi layers. For such layers, this button restores the layer standard parameters (if these parameters were previously changed by the user).

Restore default layer for selected BIM class  - assigns to the currently defined BIM class the layer that is defined in the CADprofi standard.

Layer properties – this option allows to change the properties of the selected layer. It is not available if the "by parent class" is selected (in this case it is necessary to go to the parent class by clicking the "Go to the parent class" button).

Filter list of layers – enabling this option allows to display on the list only these layers, which have similar names.

Layer management

CADprofi layer structure

Names used for layers that are automatically created by CADprofi consist of several parts:

•    First 3 characters define the design branch and the type of the created drawing (2D, 3D etc.).

•    Next characters define the type of object e.g. a symbol, line, duct etc.

•    The ending of the layer name is used to define the belonging of object to a specific installation, type of material, line type, wall etc. (e.g. S-Supply, R-Return, I-Supply air). The ending is created by using the extended layer structure (check page 32).

It is also possible to create additional layers in CADprofi program such as these that show the drawing details (details, axes, hidings) as well as special layers.

Layer colours

Colours of automatic layer structure are adapted to the black screen background. For ergonomic reasons only certain colours from the 10 to 249 range are used. If the colour is defined by a standard then user should use the colour accordingly to the standard, e.g. a supply line used in central heating should have a red colour (or a red tint). For objects whose colour does not depend on the standards user should use colours that makes it convenient to assign them to the print thickness. Plot styles: „CADprofi Color” and „CADprofi Mono” have got defined 4 line widths. Below is a table of colours for each line width.

18, 28 ... 19, 29 ... colours don't have a defined print width (they have got the object width set) and are not used in CADprofi program. User can use these colours without fear of conflict with the program's layer structure (colours).
