Dialog Settings: 3D import

In this dialog define the settings for importing STEP files.

Note:

EPLAN supports solely the import of STEP files that have been generated with the application protocol AP 203 or AP 214.

Overview of the main dialog elements:

Automatically assigned function definition after import:

Function definition receiving imported 3D objects from the STEP file; set to "Part placement, normal item". Use the [...] button to select other function definitions.

Degree of detailing:

To adjust the data volume upon import of STEP files, you can pre-select the degree of detailing with a slide control. There are five settings between the following values:

A low degree of detailing accelerates the import of large STEP files, but does result in a rougher representation of roundings. A high degree of detailing improves the representation of roundings, but also increases the data volume and time required for the import.

Separate items:

The behavior during import depends on the treatment of the STEP file by the issuing CAD system. Prior to the import the STEP file is analyzed and it is determined which organizational structure it has.

If, during STEP import, this check box is activated, several logic items are generated if several individual bodies / surfaces can be found in the imported STEP file which were not combined organizationally by the generating CAD system.

If the check box is deactivated, the individual bodies / surfaces are no longer separated in the STEP file into several logic items; instead, one logic item is generated.

If the STEP file contains assemblies whose bodies were combined into one unit by the generating CAD system, all combined bodies are generally separated - independent of the setting of this check box.

Tip:

To combine subsequently several individual bodies, the function Edit > Graphic > Unite can be used.

Correcting normal vectors and orientation:

The normal vector of a surface determines whether the surface faces the viewer or is turned away from him / her. STEP files can contain surfaces the normal vectors of which are pointing inside; such surfaces are then interpreted as transparent.

If this check box is activated, the respective surfaces are generated during the import so that they are not transparent from both sides.

Note:

Correction of the normal vectors can only be carried out at complete closed objects. The Separate items has to be deactivated in order to activate correction. Both settings cannot be used together.
