Drag (HCM 3-D)

This function activates an "automatic constraint search". The automatic constraint search looks for geometries which have constraints that match the moved geometry. You can use RET to apply the constraints that are found or use the context menu (RMB) to select another constraint.

This function enables you to use the mouse to move a 3-D part. Two-dimensional movements are translated into three-dimensional movements of the object.

First, identify the geometry that you want to be moved. If this geometry is fixed, you will be asked whether you want the fix to be temporarily removed. Once you have identified the geometry, you can use the cursor to move the object.

HCM 3-D now attempts to keep the object as close as possible to the path of the cursor, while complying with the assigned constraints. If this is not possible, because a constraint would be infringed if the object moved to the cursor position, the mouse pointer stops at the last correct position and a smaller cursor displays the currently sought position. Only when this smaller cursor reaches a correct position, does the display switch to the normal state.

You can end dragging as follows:

• using RET, with the object then assuming the last correct position.
• using END, with the object then being moved back to the position it occupied before dragging.

This function enables you to rotate a 3-D part about a defined axis.

First, use the Dragger Rotation Axis to define a rotation axis. Identify the geometry that you want to be rotated and move the cursor.

The movements of the cursor are translated into rotation movements. The geometry is now rotated about this axis by means of upwards and downwards movements of the cursor, with the screen height being equivalent to precisely one revolution.

Note: The same rules as for the Move function apply to infringements of constraints and ending the function.

This function makes dragging a value available as an option.

Identify a distance or angle constraint. You can change this value dynamically by moving the cursor up and down. In the case of distance constraints, the dimensioning is always automatically adjusted.

The cursor display also switches here if the selected constraint cannot accept the desired value. Use RET to apply the changed value. You can then confirm the current value or correct it. You can use END to restore the initial value.

Note: You can also access this function via the context menu of a dimensional constraint. To do this, right-click the dimensional constraints in the drawing.

Drag plane/Rotation axis function:

Use this function to define an edge as a static rotation axis, about which a part is rotated. Identify thepart and execute the Rotation simulation.
