LinkCAD for ANSYS®

ROBUST Translator for the ANSYS simulators

Support your ANSYS investment with LinkCAD for ANSYS which improves productivity from day one

Quickly load 2D GDS-II, DXF, CIF, Gerber RS-274X or ACIS/SAT into ANSYS 3D programs for Analysis.
This powerful translating utility converts 2D GDS-II, DXF, CIF, or Gerber RS-274X into the ANSYS 3D file formats ANSYS ANF and the Workbench compatible Parasolid XT. This means LinkCAD will meet all your file transfer needs for the ANSYS simulation modelers.

As an added benefit, without using ANSYS GDS-II, CIF, DXFGerber and PostScript files can be imported and exported. For photo plots and high quality prints/masks, Gerber RS-274X and PostScript output are provided.

Over 2,000 users can attest to the fast, easy translating abilities. User E Miller says . . .

"It seems the Electrical Engineer a few cubicles over is always throwing out a new file format that you have to struggle to read. This tool can truly remove a lot of pain for a lot of users. It adds the ability to output EE layout geometry directly to ANSYS. No IGES, no importing into a 2D CAD system to clean-up, no custom readers."

The following table shows all of the input and output formats supported.

GDS-II Yes Yes
IE3D Yes Yes

LinkCAD for ANSYS includes the following Standard Features:

1. All Import - Export formats Listed Above

2. Automatic File Read and Repair

Simple operation is key to this software. Just select the import and export format, click on "Next" and you are guided thought the conversion process in a "Wizard-like" format. While translation is provided, these common CAD issues are resolved in the process.

  • Circles in DXF need to be converted to closed polygons for ANSYS, CIF, GDS-II and Gerber files. Selection of the number of segments to make up a circle is available. This is important for ANSYS modelers where a reduced number of segments will keep simulation time to a minimum. Or the reverse is required for manufacturing, where a high number of segments are needed.
  • Repair problem DXF files. Click a box and LinkCAD will fix DXF broken polylines or open polylines.
  • Use the easy Flatten command will remove hierarchy from files for use in hierarchy sensitive applications.
  • 200 vertices/polygon requirements. GDS-II file format supports a maximum of 200 vertices/polygon. LinkCAD will scan the number of vertices in each polygon and if it exceeds the 200 vertex limit, it will break the polygon into the needed number of polygons in order to meet the 200 vertex criteria. This is important for DXF to GDS-II conversions where AutoCAD polygons do not have any limits.

3. Layers Management

An unlimited number of layers are supported. "Layer Map" provides the ability to make a selection of only the layers to be exported. This means you can import a complete file and export ONLY the layers that are needed. The Layer Map standard feature allows changes to the name of the layers, e.g. Layer 5 can be changed to layer 50 by entering the value to the right of the listed layer. The Z axis vlaue is also endered to automate the conversion process.

Turn off layers by clicking on the 'light bulb' in the layer map window.

4. GDS-TXT (Binary to Text)

Now GDS-II binary files are no longer a road- block to getting your design changed and into production. This unique editing software converts GDS-II files into easy-to-read and edit ASCII files. This means redundant editing changes can be done with just a few key strokes. Interface to other CAD and manufacturing process can be done with easy-to-edit text files.
  • Import the GDS-II file into LinkCAD, export a text file and then use your favorite text editor to search and replace redundant changes. Change a cell or change a dimension. Then Import the text file into LinkCAD and Export a GDS-II file.
  • Change a cell or change a dimension.
  • Then Import the Text file into LinkCAD and Export a GDS-II file.


The Gerber feature creates a file for photoplotters that generate film (artwork) used to etch printed circuit boards. It will also import the Gerber format for conversion to another format such as GDS-II or DXF. Used primarily for PCB's, Gerber is also used in a wide variety of manufacturing processes. When the 2D CAD file is complete with geometries placed on layers, LinkCAD gets you to manufacturing faster. The CAD file, typically DXF or GDS-II is Imported and LinkCAD converts this information, on each layer, to a format that photplotters use to create film.

6. Simulation Integration

Critical to successful and efficient ANSYS system use, the SI feature allows you to Import 3D files in the ASIC/SAT format or files from IE3D or Sonnet. Run simulations and tests, then Export 2D files for manufacturing, typically in GDS-II. Put yourself a step ahead in the MEMs market.

7. Real World Help - FAST

LinkCAD for ANSYS Options

Option 1 - VIEW - $300.00

See what you are doing before you do it! It is an idea who's time has come. Now you can view the imported file before and after modifications, before you export. This can save time and costs because you see the results before you click on that Export button. This universal CAD file viewer is extremely fast and even features hardware accelerated rendering.

  • If you are not sure you have the correct file to convert, import the file and use VIEW to confirm it is the correct file.
  • If your file has broken polylines (DXF files), VIEW will highlight the 'broken' polylines and let you determine if you want to repair them using the 'Join' or the 'Add Width' to wire options.
  • If you need to remove a layer and are not sure how it is identified, use VIEW to confirm you selected the correct layer to be turned off.
  • If you are not sure of a DXF file scale, you can import and use the VIEW 'Distance' command to check the dimensions of a known segment length.
View the file before you export - A broken file has been identified with a broken line and triangles at end of segments.

Below is an example of how geometries can be repaired and LinkCAD VIEW will show the results
before the file is exported.

Repair window defines two open polygons.

The results show the rectangle is filled.

Option 2 - TOOLS - $300.00

Merge Overlapping Polygons
The Merge option will merge overlapping polygons into one geometry. This is great for mechanical and electrical simulators and other software that will not accept overlapping polygons such as the IE3D em simulator. The algorithm speed is extremely fast. Merge over 40,000 overlaps in less than one minute.
Merge will operate on geometries on the same layer or perform boolean functions on geometries on different layers.

Geometries on Same Layer

The two sets of geometries on the right show a series of pads created by circles and line draws to form 'tear drop' pads that are highly resistant to circuit breaks on a printed circuit board.

Left Image- Separate line draws created by the CAD system.
Right - Single geometries after the Merge operation.
Geometries on Different Layers
This design shows a plane on one layer and pads on another layer. Using the Layer Operations, Boolean functions can be performed on the geometries of the two layers.
Seen below, pads on one layer are subtracted from the plane on a second layer. Operations of Merge (OR), Intersect (AND), Subtract (as this example) and XOR are available. These operations are useful as a complement to the CAD system.

Blue pads can be used to 'punch holes' in magenta plane.

After the boolean function (AND) 'Subtract', the plane has resultant holes.

Subtract (XOR) Overlapping Polygons

Original geometries consist of one large plane and two smaller geometries that are on the same layer. XOR command creates holes in the plane that are the shape of the smaller geometries. The XOR command will perform the operation on any layer that is turned on. If more than one layer is in the database, layers can be turned off before the command is executed.

Join Adjacent Wires Feature

Independent segments may cause problems. After Join Adjacent Wires command.

Option 3 - EDIT - $200.00

The edit option provides the ability to delete geometries from a single layer.

The typical application is when a layer is brought in with multiple geometries on one layer and one of those geometries is the boundary of the circuit. Unfortunately, often all you can see is the boarder and not the items inside.

EDIT lets you delete that boundary, without going back to a CAD system, thereby making the interior geometries visible and accessible.

The imported layer has a boundary and you are not able to see the geometries inside (represented by the grey lines) without going back to your CAD system.

EDIT allows you to delete the boundary, while in LinkCAD. Now the geometries are accessible.
