Moving Models With Grip Snap

The Grip Snap tool provides several methods for moving and rotating models. When you select a point or an edge on a model, a mini-toolbar displays with options for moving the model.

Tip: Navisworks displays models as faceted surfaces. As a result, you can inadvertently select facet edges and points on surfaces that do not correspond to model edges. For example, a circle is represented as a polygon. If you change the display mode to Hidden Line (Viewpoint tab Render Style panel Mode), the facet lines display on top of the surface.

Each mini-toolbar provides three options for moving the model. Once you select an edge or a vertex on the model, the mini-toolbar appears. You can press Tab to cycle through each of the mini-toolbar options. Click the Back option on the far right of the mini-toolbar to cancel the edge or vertex you selected, and then you can select a different edge or vertex on the model again.

Once you start to move the model, you can press Esc to cancel the move, and then press Esc a second time to cancel the command.

• Free Drag is available for both Edge and Point selections. The model is attached to the pointer, and you can manually move the model to a different location. The model snaps to the floor grid and other model geometry.
• Move Using Reference Geometry is available for both Edge and Point selections. It repositions the model based on selections on another model. The orientation of the model does not change.
• Drag Along Ray is only available for Edge selections. You can dynamically drag the model along the infinite line defined by the selected edge. Or, you can enter a specific value in the Heads-Up Display (HUD).
  
• Rotate About Point is only available for Point selections. You can dynamically rotate the model around the selected point. The rotation is restricted to the XY plane. You can also enter a specific angular value in the Heads-Up Display (HUD).
  
• The Back button cancels the current selection and keeps the Grip Snap command active so you can select other geometry.

You can move one or several models with the Grip Snap command. The model with the selected geometry always moves. To move multiple models, press and hold the CTRL key while selecting them in the graphics window before you start the command. Or, you can select the models from the Selection Tree after starting the command. If you start the command without preselecting models, you can only move the model with the selected geometry. If multiple models are preselected, and you select geometry on a different model, the preselection set is cleared and only the last model moves.
