DXF Import

, ,
Description

These setting are used for importing CAD files with DXF files. The importing of DXF files is described in detail in tutorial 3.

These settings must be determined before the DXF file is opened.

Fields

1 Unit corresponds

In DXF files geometric information is saved without units. For drawings, which are not scaled, 1 unit represents 1 millimeter in Europe. In scaled drawings, the units can be adjusted respectively (i.e. in the scale 1:1000 1 unit represents 1 meter).

Transform all points to grid points

Determines whether all DXF object points (end and midpoints) should automatically be mapped on a grid.

Grid width

Sets the distance of the squares within the grid, on which all end and midpoints of the DXF object should be mapped.

Reference circle radius

 

No. of points for the polygon approximation of ref. circle

Upon importing a DXF file, arcs and circles are divided into individual segments. You can determine the accuracy of the approximation by adjusting the radius and the number of points for the polygon approximation of a circle:

- All circles with radii smaller than the reference circle's radius will be subdivided, proportionally to radius, less than the reference circle.

- All circles with radii bigger than the reference circle's radius will be subdivided, proportionally to radius, more than the reference circle;

Minimum number of edges for an arc

This setting determines the minimum number of edges for arc approximation.

Determines an internal calculation for the number of edges of a specific arc (taking into account the "Reference circle radius"), which according to the polygon circular approximation, would have fewer edges than this parameter value. If this is the case, this parameter is used instead.

Use auto correction

Is this option is selected, all open polylines or not connected lines will be automatically closed, if the gap is smaller than the defined value.

Assign material

In this list you can define the standard characteristics when converting imported DXF data.

Level: The material which is defined in the layer material mapping table is assigned automatically to all objects lying on the DXF-layer.

Layer - only closed objects: The material which is defined in the layer material mapping table is assigned automatically to all closed objects (e.g. polylines) lying on the DXF layer.

Selected material: The selected material from the Material list is assigned to all objects.

You can also change the kind of material assignment by clicking on the "Options" button in the message line after importing the DXF file. The automatic material assignment is explained in tutorial 3.

Don't import turned off layers

If this option is selected, the hidden layers in the DXF file are not imported. Otherwise they are imported but not displayed. You can change the visibility of the layers in the Layers flyout

Use only shady drawn edges

This option determines, whether the entire line segment or just the end points of unclosed lines should be highlighted or not.

Special Color

Determines if and which color should be used when there is a problem spot.
