DDScad DWG/DXF Conversion¶
DXF/DWG Conversion¶
DDScad has its own viewer for DXF/DWG. We can use this to convert between the DDScad format (CFI) and AutoCAD formats (DXF/DWG).
Opening DXF/DWG Files in DDScad¶
Instructions
- Select File - Open when you are inside a drawing, or have closed the project with the Close button in the drawing list
- Select file type DXF/DWG file and browse to the folder where the file is located
- Select the file and click Open
Info
We can also use the DDScad platform to export the content of terrain models and presentation drawings to DXF/DWG. This is the DDScad platform's export function for drawings and has nothing to do with the conversion module for application layers.
DDScad's export function exports what is displayed on the screen. However, Gemini Terrain has data that is unknown to DDScad's function, such as metadata, hyperlinks, point clouds, etc.
Therefore, an extended DXF/DWG export has been created that also handles Gemini Terrain data.
Exporting to DXF/DWG with DDScad¶
When working in drawings, we can export the screen content to DXF/DWG at any time.
Instructions
- Select File - Export - Export to DXF/DWG
- Enter the file name and click Save
Exporting to DXF/DWG with Gemini Extensions¶
When working in drawings, we can export the screen content to DXF/DWG at any time.
Instructions
- Select File - Export - Export to DWG (Gemini extensions)
- Enter the file name and click Save
Note
Note that we get different results when exporting from plan and 3D views. When exporting from 3D view, only geometry that forms surfaces will be included. Application layers and other Gemini objects will mostly end up on predefined drawing layers. Drawing layers in the DDScad platform become Layers in the DXF/DWG file.
We have some options to control the connection between Gemini objects and drawing layers. These are described below.
Application Layers¶
For application layers, we can link a property to a drawing layer. If we, for example, link S_FCODE (theme code) to a drawing layer, each theme code will create a layer in the DXF/DWG file. In addition, we can also use separate layers for annotations.
Example¶
| Name | Number | Note |
|---|---|---|
| 2001 Contour line | 2000 | |
| 2200 Terrain line | 2001 | |
| 2206 TerrainLineBuilding | 2002 | |
| 2003 Depression contour | 2003 | |
| Terrain_Id | 9000 | |
| Terrain_Elevation | 9001 |
The options for this can be found under Options for application layer.
Objects in the Command List¶
All commands in the command list have a separate tab Property that contains the link between the object and the drawing layer. Gemini objects are by default linked to predefined layers.
For SFI models, intersections, and excavation pits, we can also use separate layers for each VIPS surface group.
Note
This option only applies to 3D presentation.
Example¶
| Name | Number | Note |
|---|---|---|
| Roadway, VIPS surface 1 | 911 | |
| Shoulder, VIPS surface 2 | 912 | |
| Ditch, VIPS surface 4 | 914 | |
| Soil cutting, VIPS surface 6 | 916 | |
| Fill, VIPS surface 7 | 917 |
The option for this can be found under Options for planning, design and execution.
