Import data from a 3D DXF file

See the following paragraphs for the restrictions of 3D DXF import, and the instructions on importing data from a 3D DXF file.

Restrictions

Note the following points when importing 3D DXF files:

Round tripping does not exist in 3D DXF file imports. This means that the import data is used to create new objects in the model, not to update existing ones. All existing objects and data are maintained.
Analysis elements are created from line segments in the selected layers of the DXF file as follows:
- All lines in these layers become 1D analysis elements.
- Arcs and circles in the selected layers are excluded without a warning.
- Blocks are not handled, and no warnings are issued.
- Polylines in the selected layers are excluded without a warning.
- 3D solids in the selected layers are excluded without any warning.
- 2D faces for 3D objects in the selected layers are excluded without a warning.
- All ends of lines in the selected layers become nodes.
- Nodes are not introduced in the intersections of crossing lines.
- The following elements are not included in the import:
  - Reading of any text
  - Intelligence on "through members"
  - Gridlines and construction lines
  - 2D elements
  - Supports
  - Section properties
  - Materials
  - Loads
  - Combinations

On the BIM Integration tab, click 3D DXF Import.

Note:
3D DXF Import can only be selected in a 3D view.

The Open dialog opens.
Browse to the required .dxf file.
Click Open.

The Import 3D DXF dialog opens.
Make appropriate selections in the dialog:
1. Select the layers and colors that you want to import.
2. Confirm the correct DXF units are selected.
3. If necessary, apply a scale factor.
4. If necessary, apply X, Y, Z offsets and/or a rotatation about the global Z axis.
Click OK.

Any line segments found in the selected layers are now imported as analysis elements.
