Troubleshooting

Can't Offset the Part

Condition

I can't create a matching offset for the part. In the Model Browser, the part is displayed in red and when I hover over it, an error message is displayed saying that the "Part failed to offset."

Cause

The imported part cannot be offset and needs to be modified.

Do one of the following:
  • In the guide bar of the Matching Die tool, change the Offset multiplier.
  • Go back to the Part tool and adjust the Thickness.

Cause 2

When you selected Apply Smoothing, some ribs were automatically moved to smoothen the addendum wall where it intersects the binder. When the ribs were moved, they became overlapped or too close.

Remedy 2A: Fix Overlapping Ribs

Overlapping ribs is the most common issue, so we suggest starting off by fixing them manually.

  1. Adjust the view as necessary to locate overlapping ribs.
  2. Rotate the ribs so that they don't overlap by doing one of the following:
    • Hover over the rail to display handles. Drag the lower arrow to change the angle of the rib plane.
    • Select a handle and enter an Angle in the microdialog.
    Note: If a rib can't be rotated, select the rib, and in the microdialog turn off the constraint Tangency G1 to the part so that you can rotate it.

Remedy 2B: Delete Excess Ribs

Check for ribs that are too close together or lie on the same plane, and then manually delete excess ribs.

  1. Adjust the view as necessary to locate ribs that are too close together or lie on the same plane.
  2. Delete ribs as necessary to smoothen the flow.
    1. In the guide bar, select Edit Ribs.

    2. To delete a rib, select it and press Delete.
      Note: If the rib is essential for maintaing the desired addendum shape, instead of deleting it, you can rotate it as described above.

Can't Offset the Addendum

Condition

The part offset worked, but I can't create a matching offset for the addendum. In the Model Browser, the part is displayed in red and when I hover over it, an error message is displayed saying that the "Addendum failed to offset."

Cause

The Addendum configuration at some rib locations was set to Auto Decide Tangency or Break Addendum Start Line. As a result, gaps occur at these locations, preventing further trimming and the creation of the addendum offset.

Remedy

  1. Identify unsmooth areas to locate ribs where the Addendum configuration was set to Auto Decide Tangency or Break Addendum Start Line.
  2. To smoothen the area, try the following:
    1. Change the Addendum configuration to Tangency (G1). If that doesn't help, leave it at Auto Decide Tangency.
    2. If the previous step doesn't work, copy the selected rib. Paste two copies, one on either side of the original rib. Set the copies to Tangemcy (G1).

Fillets Missing from the Die

Condition

A matching die was created, but there are missing fillets.

The fillet radius on the die is too small, resulting in sharp edges during the offset.

Remedy

Do one of the following:
  • Using the Die tool, increase the fillet Radius.
  • From the Modify ribbon, use the Round tool to add fillets where they are missing.
