KOMPAS-3D v23

When a KOMPAS document is exported to DXF or DWG format, there are several ways to export objects located in different layers:

•objects placement in their dedicated layers,

•groups of KOMPAS-3D layers may be merged into AutoCAD layers;

•objects placement in layers.

Depending on the color settings (see section Setting object colorsObjects in the resulting document can be displayed with their own colors or the color of their layer.

The layer states in the resulting document depend on the states of layers and their master views in the document being converted (see Table below).

In KOMPAS-3D, the state of views and layers is defined by the combination of two properties: activity and visibility. The values of the activity property are "active" and "background". The values of the visibility property are "visible" and "hidden". In AutoCAD, the state of a layer is defined by the «unlocked»/«locked» and «enabled»/«disabled» properties. These properties function similar to the aforementioned KOMPAS-3D properties.

•If a layer of the KOMPAS document is not visible (i. e. it's hidden ot it is located in a hidden layer), then this layer will be disabled and unlocked in the AutoCAD document regardless of the activity property.

•If a layer is visible in the KOMPAS document, this layer will be enabled in the AutoCAD document. The active layer becomes "unlocked", and the background layer becomes "locked".

Thus the exported document, when opened in AutoCAD, will have the closest possible condition to the original KOMPAS-3D document prior to conversion.

Layer states when exporting KOMPAS-3D documents to AutoCAD

In addition to layers exported from KOMPAS-3D, a system layer with the name "0" is generated in the resulting DXF or DWG document. When the KOMPAS drawing is exported, the following objects are placed on that layer:

•sheet detailing (border and title block),

•unspecified surface finish mark,

•technical specifications;

•BOM on sheet,

•revisions table.

Placing objects in their dedicated layers

If the Unite same name layers in one and Distribute KOMPAS objects by AutoCAD layers on the Layers page are disabled, then the number of layers in the AutoCAD document will be the same as in the exported document. That is, during export all objects are placed in their dedicated layers. The layers are named according to the following rule:

•of the name of the layer is unique within the document, it remains unchanged,

•if there are several layers with identical names, serial numbers are appended to the names, starting with 1,

•if a layer has no name, the name "LAYER" is assigned to it;

•if there are several layers with no name, the name "LAYER" followed by the serial number starting with 1 is assigned to them.

Examples of naming layers according to this rule are provided in the table below.

Merging layers

In AutoCAD document it’s possible to create a layer combining several layers of the KOMPAS. The layers may be merged if the following properties are identical:

•names,

•colors,

•states.

To enable merging of layers, please enable the Unite same name layers in one setting on the Layers page. This means that after you define the layer states (see Table Layer states when exporting KOMPAS-3D documents to AutoCAD) among them, groups of layers with matching parameters (states, names, colors) will be highlighted. Layers of each group will then be merged into new layers. The resulting layers are named according to the following rule:

•of the name of the resulting layer is unique within the document, it remains unchanged,

•if there are several resulting layers with identical names (with different color or status), serial numbers are appended to the names, starting with 1.

If some layers cannot be merged, they are placed on different layers in the resulting document. They are named according to the rules set out in section Placing objects in their dedicated layers.

Objects placement on layers

Using the Distribute KOMPAS objects by AutoCAD layers setting on the Layers page, you can generate dedicated layers for various KOMPAS objects (detailing, texts, hatching, dimensions, etc.) and curves with different line styles. In other words, using the Layers page, you can set up the way the KOMPAS-3D objects are distributed in the AutoCAD layers without preserving the original layer structure. This may be required to ensure the exported drawings are consistent with the company standards.

In the view window, a table is displayed with the list of KOMPAS-3D object categories, and AutoCAD layers colors and names to place these objects by default.

To modify the color of a layer, click the color cell and select the new color in the dialog box.

To rename a layer, click the cell in the Layer column and enter the new name.

If you want to create the layers similar to the KOMPAS-3D layers to place the objects of the selected category, please enable the Place object on source layer setting in the leftmost column. When you are done, press the Save button.

To save the settings made in the file, click the Save to file button. In the dialog that appears, specify the name of the file to be written. The software will generate a binary file with information about AutoCAD layer names and colors for KOMPAS-3D objects (*.lac).

To use a previously created *.lac file, click File.

To discard custom placement of KOMPAS-3D objects in AutoCAD layers, click the By Default .
