(This functionality is available with the Input / Output module)
Imports data from AutoCAD DWG, DXB and DXF files.
Refer also to the Import dialog box topic.
AutoCAD block names are treated as feature codes. Therefore the symbol associated with a feature code in the code table will be used if that feature code is matched to a block name either directly or via a lookup table.
If "Alternate Coding" is selected:
- AutoCAD layer names in the imported file will be treated as feature codes by the system, otherwise, the layer name will become the group name.
- If the AutoCAD file is 3D, a text element will be treated as a LISCAD point whose description is the text. This will only occur if the LISCAD code matching the text element's layer name is set as contourable.
During the import process an AutoCAD Import dialog will appear that allows the user to select the scale factor, explode AutoCAD blocks and segment polylines and lightweight polylines into individual line segments and to form polygons from the polylines.
The following table describes what AutoCAD entities are imported into LISCAD, and what LISCAD entity they then become...
| AutoCAD Entity | LISCAD Entity |
| Point | Point |
| Shape | Points |
| Line | Line |
| Arc | If 3d, then Spline, else Arc. |
| Circle | If 3d, then Spline, else Circle. |
| Trace | Line |
| Solid | Line |
| Face | Line |
| Polyline | Line |
| 2D Polyline | Line/Spline |
| 3D Polyline | Line/Spline |
| Spline | Spline |
| Text | Text |
| Block Reference | Either a symbol, or the block is exploded and the constituent entities imported |
| Ellipse | Spline |
| Region | The region is exploded and the constituent entities imported |
| Hatch | Polygon |
| Proxy | The entity is exploded and the constituent entities imported |
| 3d Solid | The entity is exploded and the constituent entities imported |
