In each step you can hide measurement line if they are not needed for the work in the 3D work area.
Hiding a measurement line is possible only if while you were adding it for the first time, in the contextual edit bar you left empty the Hide in next step check box (see how to add measurement lines (Step 1)). This ensures that the added measurement line will be visible in the next step of the folding sequence.
NOTE ON MEASURE LINES EXPORT: When a 3D model is exported, an option exists for exporting the measure lines added to it. If the option is elected, the measure lines are exported regardless if they are hidden in the 3D work area.
To hide a measurement line
The measurement line disappears in the 3D work area, but can be inspected in the tabular area: click the Dimensions tab and in the Dimension Type column locate the line. Note that now in the Visible column it appears as Hidden.
To visualize a hidden measurement line
A dropdown list appears in the field.
The measurement line is now visible in the 3D work area in the active step. If you need it visible in other steps, repeat the procedure for each step in which you need it visible.
