DXF Export Options dialog box

The DXF Export Options dialog box is opened when you are using the File => Export command to save your geometry project as a DXF file. The available options are explained below.

Separate By Object Types: Select this checkbox to create a separate DXF layer for each object type in the Sonnet level, i.e., metal polygons, brick polygons and vias. For an example, if your Sonnet level has both metal polygons and vias, two DXF layers would be created, one containing the metal polygons and another containing the vias.

Separate By Material Types: Select this checkbox to create a separate DXF layer for each type of material in the Sonnet level, i.e., two different types of metal. For an example, if your Sonnet level has both copper and lossless metal polygons, two DXF layers would be created, one containing the copper polygons and another containing the lossless polygons. This would also be true for dielectric brick materials.

Divide Multi-layer Vias: A via in Sonnet which extends over two levels or more, is translated into separate vias for each DXF layer. For instance, in the picture below, the original via, shown on the left, extends from level 0 down to level 3. In the translation, this via would be replaced with three single-layer vias as shown on the right.

Keep Edge Via Parent: Selecting this checkbox causes a metal polygon with an edge via to be translated as a via of the same size and shape as the metal polygon. If this option is not selected, then neither the metal polygon or the edge via is translated. This option is only used if the Separate By Object Types option, described above, is selected.

NOTE: Please note that the metal polygon is also translated as metal.

Convert Vias to Circles: Selecting this checkbox converts the vias in your Sonnet project to circular vias in your DXF output. If you select the Auto radio button, then the circle is the biggest that can fit in the bounding box of the via polygon, as shown below.

Select the Manual radio button if you wish to enter the desired radius of the circular via in the text entry box to the right.

NOTE: Please note that if you enter a manual radius, then ALL the vias in your circuit are converted to circular vias of that size.

Export: This section of the dialog box allows you to choose which objects in your Sonnet project file you wish to export to the DXF file. To export the type of object, select the checkbox next to the item. The objects are Metal Polygons, Edge Vias with their attached polygon, via polygons, Edge Vias and Brick Polygon. If the checkbox is not selected, then that type of object is not included in the DXF file.
