How to export a DXF reference file for a project

You can export a Tygron Project to a DXF reference file for use in CAD programs. You can use this DXF as a reference in AutoCAD with the correct Geo Plugin layers to draw a new plan. Another benefit is that the exported DXF is Geo referenced to the correct coördinates set in the Tygron Project. In this way the DXF can be reimported to the project which it came from without a faulty coordinate system.

Editor → Tools (Ribbon tab) → Geo Plugins (Ribbon bar)

How to export a DXF reference file:

1. Go to Geo Plugins in the Tools tab. Click on it to show the current Geo Plugins available in your project. They can be found on the left panel of the Editor
2. If you do not have a Geo Plugin set up, go to How to create a Geo Plugin to import Buildings from a DXF.
3. If you do have a Geo Plugin, click on it and it's properties will be shown on the Right Panel.
4. Click on the Geo Link tab. A list of GeoLinks will be shown. This is a list of Tygron Functions which will be converted to CAD layers when exported to DXF.
5. Go to the Tools tab in the Editor Ribbon and hover over the Geo Plugin dropdown menu. Choose Export AutoCAD DXF Reference. This will open an export dialog window.
6. Ensure the "Export Buildings (Attribute)" option is selected.
7. Ensure the "Export Roads" option is selected.
8. Leave "Area of Interest" as is.
9. Click on the CRS: Edit link to change you Coördinate Reference System or leave as default. The default system is the same as your Tygron Project Reference System so when re-importing your DXF these will match.
10. Finally choose a Geo Plugin from the dropdown list. This Geo Plugin will be used to create the Layers in DXF.
11. Click on "Export File" and save the DXF to a location on your computer.
12. You can open the DXF in AutoCAD or other packages that support DXF.
13. To re-import your edited DXF follow the How to import a DXF tutorial.

Notes

• The Building Attribute selected during export dictates which Building features are part of the DXF's background layer. SOLID is the default setting as it provides all large structures which is generally sufficient context.
• The Area of Interest option works similar to the Building Attribute option, in that it will add all Areas with that Attribute to the export as well. AREA_OF_INTEREST is the default setting, and will match the Attribute added to Areas used for Project generation.
