ACIS Compatibility - Errors and Warnings

You can check the ACIS compatibility of the geometry. You can print the geometry of the assembly into a file and view its contents.

At worst, ACIS errors can cause Vertex to crash, or prevent the cutting of parts in assembly drawings. You can look for ACIS errors in the following ways.

ACIS binary file (*.sab) read and write

SAB format is a binary form of SAT format, and it is a bit lighter. It is intended for converting parts.

Part / Assembly Part

  1. Open the part model in the working window or open the part model for editing in the assembly.
  2. Press Shift+C.
  3. The result of the ACIS check is displayed in the dialog box.
    • ACIS errors and warnings are recorded in the list.
    • Errors and warnings are presented in numerical order. View the errors.

      Select individual from the error/warning list. You can select several items in the list. Your selection is highlighted in a different color in the model.

      ACIS check window opens. The result is in the ACIS window.

      For example, 1 lumps, shells, 0 wires, 77 loops, 77 faces, 410 coedges, 205 edges, 130 vertices.

    • Result:

      Error Edge marked as tangent incorrectly, intersection failed, for example.

  4. Click OK.
  5. Finish by doing either of the following:
    • Click OK. The markings remain visible in the model.
    • Press the Esc key. The markings disappear.

Assembly

Find parts containing ACIS errors from an assembly models as follows:

  1. Open the assembly model in the working window.
  2. Select the name of the assembly from the assembly tree.
  3. Select the context-sensitive function Other Functions> Model Data to File. A text file opens.
  4. You can look for parts with errors from the file by entering the following text: ACIS geometry.
    • If the text you entered is found in the file, you can identify the part with errors.
    • If the text you entered is not found in the file, the model geometry has no errors.
