Open the FSS_CCK_Surface_Curve01.CATPart document.

1. Click Connect Checker Analysis in the Shape Analysis toolbar.

2. Select both the curve and the surface to be analyzed.

3. Click Connect Checker in the dialog box and Projection option in the Connect Checker analysis dashboard.

The Connect Checker dialog box is displayed as well as another dialog box showing the color scale and identifying the maximum and minimum values for the analysis type.

There's no Boundary  mode available for Surface-Curve connection.

The Auto Min Max button enables to automatically update the minimum and maximum values (and consequently all values between) each time they are modified.

4. Select either of the options: G0, G1 or G2. You can choose the type of analysis to be performed using the combination: G0, G1, G2, or G3. The G3 and Overlap options are not available in Projection for the Curve-Curve option.

5. Set the Maximum gap and Minimum gap for the connection analysis. The Connect Checker measures the gap of every connection between each of the borders of each of the geometrical elements, irrespective of the size of the elements.
• If the value of the gap is greater than Minimum Gap and less than Maximum Gap, the connection is analyzed.
• If the value of the gap is outside of these limits, the connection is not analyzed.
  There may be instances (such as very small elements, or very large Maximum Gap) where the system finds connections which are unexpected. In these instances, adjust the value of Maximum Gap until the unexpected connections are eliminated.

6. Check the analysis results on the geometry. The subsequent sections show the result of connecting a curve and a surface with a combination between G0, G1 or G2 and Projection.
