# DXF support

Use DXF for CAD interchange and check the imported or exported result before relying on a round trip.

Use **DXF** to bring CAD drawing content into Synaps or hand drawing geometry to another CAD application.

## Import a DXF drawing

Open **Import**, choose **DXF**, and select the file. Inspect the resulting drawing before developing it further.

The importer handles common drawing content, including lines, polylines, arcs, circles, text, fills and hatches. Check the converted content using the table below.

Import a DXF drawing and inspect the geometry on the canvas.

## Check dimensions and specialised content

| Content                                           | What to check                                                                                     |
| ------------------------------------------------- | ------------------------------------------------------------------------------------------------- |
| Linear and aligned dimensions                     | These have an import path; check their positions, values and appearance.                          |
| Angular, radial, diameter and ordinate dimensions | These are not supported by the dimension import path.                                             |
| Ellipses and curves                               | Compare the curve shape and endpoints with the source drawing.                                    |
| Text                                              | Check fonts, alignment and multiline formatting.                                                  |
| Hatches and fills                                 | Check boundaries, holes, pattern scale and appearance.                                            |
| Images and embedded content                       | Check that referenced images and embedded content are present; add missing references separately. |
| Layout viewports                                  | These are not imported as working layout viewports.                                               |

## Export to DXF

Select a drawing paper and choose **DXF** in its **Export** properties. Open the output in the recipient's CAD application and check geometry, annotations and symbols.

Use PDF or image output for a visual deliverable; use DXF when the recipient needs drawing geometry.

## Before handing over a file

1. Check units and a known dimension.
2. Inspect curves, opening symbols, stairs and annotations.
3. Check hatches and any image-dependent content.
4. Confirm the recipient can open and use the output for the intended task.

For a DWG source, export a DXF from the originating CAD application before importing it into Synaps.
