Insert Profile Ground

The Ground Constraint command enables you to constrain a special point (an endpoint or center point) in a 2D profile or a 3D profile so that it remains fixed relative to the Reference System.

After starting the command, from the selection list, select the type of the Ground Constraint required by selecting any one of the following from the Type drop-down list:

• Ground — to constrain both the point coordinates
• X Ground — to constrain only the X-coordinate
• Y Ground — to constrain only the Y-coordinate
• Z Ground — to constrain only the Z-coordinate (only for 3D profile)

To apply the constraint, select the point to which the constraint is to be applied. If you are constraining a circle or circular arc, the following rules apply:

• Circle — the constraint is placed at the center
• Arc — the constraint can be placed at the end-point, mid-point or the center-point of the arc

The program immediately applies the constraint and adds one of the identifiers:

—  fixed in all directions  —  fixed in the X-direction  —  fixed in the Y-direction  —  fixed in the Z-direction (only for 3D profile)
