Using the Iso-Thickness Junction Wizard

Select a group of iso-thickness areas.

Optional: Select a geometrical set containing all the existing junction lines (to verify and validate existing junction lines).

Optional: Select the Optimize the input junction lines check box.

This check box is available only for a relimited ITA Group (created using an ITA limit).

Small inaccuracies found in the selected junction lines are corrected during computation. Below are three examples of correction when there is a gap between the junction line and the ITA limit:
- In the case below, the number of junction lines remains the same.
- In the case below, an extra junction line is created.
- In this last case, the junction line deviated from the ITA limit, because of the high curvature of the underlying surface. After optimization, it is correctly aligned.
A set of Imposed Thickness Points (ITP Set) is created. The ITPs are identified in the 3D area. Solid From Iso-Thickness Areas uses this ITP Set to ensure that the elevation height/offset at these points is equal to the thickness specified with the ITP.

Tip: Verify the optimization result under Check and Refine Results.

Optional: Select Do not compute junction lines

Optional: If you have selected an existing Junction Line Set as input, select the Create junction lines in new Geometrical Set check box.

If you have selected Optimize the input junction lines, the new set of junctions lines contains both optimized and non-optimized junction lines.
if you have not selected Optimize the input junction lines, the new set of junction lines contains the existing ones and the newly created ones.
In both cases, the existing set is put in NoShow.

Click Edit to edit the iso-thickness areas group.

Click Compute.

The wizard finds all the points at the corners of the iso-thickness areas of the group.
If a line between two points intersects an iso-thickness area, this line is not considered a potential junction line.
If a line between two points does not intersect an iso-thickness area, this line is considered a potential junction line.
The analysis produces several groups of points.
If a group contains only two points, the line between those two points is proposed as a junction line.
If a group contains more than two points, they are joined two by two. If plies corners coincide with a line, this line is proposed as a junction line,

The dialog box is populated with the result of the computation. The groups are displayed in the order of the statuses:

The groups of points are also displayed in the work area:

With their thickness.
With the traffic light representing their status.
With a dotted green line is the status is green but not yet validated.
With a solid green line when it is validated.
With a solid blue line when the junction line is part of an existing set.

If you have selected Optimize the input junction lines, click Edit ITPs to inspect and edit the created ITPs.

Select a line to reframe on the ITP.
Multi-selection is available.

The thickness of the ITP is displayed in the 3D area.
Edit the thickness in the Thickness box.

Select the required 3D Display options.

In the dialog box, select one or several lines and click Validate to validate the corresponding junction lines.

In the 3D area, drag the cursor over a vertex.

Click a point and drag the cursor.

The red dotted lined turns green when reaching a point belonging to another iso-thickness area or standard point, meaning a junction line will be created.

To remove any potential or validated junction line, drag the cursor over the line until a red cross appears. Click that red cross.

The junction line is removed from the preview and not created.

Click a traffic light.

Its junction lines are validated.

Check and validate all the groups.
