Edge grips let you change the size, shape, or slope of a selected slab or roof slab by moving one edge at a time. When you move the cursor over an Edge grip, a tooltip lists the available edit modes (see mode descriptions following the procedure below). After you click the Edge grip, you can cycle through the modes by pressing Ctrl.
Use the following general procedure to select an Edge grip mode and edit an edge of a slab or roof slab:
- Select the slab or roof slab you want to edit.
Edge grips are displayed.
- Move the cursor over the Edge grip on the edge you want to edit.
The list of available edit modes is displayed. (Modes differ for straight and curved edges; see descriptions below.)
- Click the Edge grip, and move the cursor slightly in the direction that you want to move the edge. If you want to use the default edit mode, proceed to the next step; otherwise, press Ctrl to cycle through the edit modes to the one you want.
- Either enter values as needed to specify a distance or position, or move the cursor until the preview is in the desired position, and then click to complete the edit and deselect the grip.
- Press Esc, or right-click, and click Deselect All to deselect the slab and turn off all grips.
Normal grip editing maintains the slope angle of the slab or roof slab regardless of the Z value of the specified point.
Note: The pivot point is unaffected by editing the slab or roof slab edges with grips.Edit Modes for Straight Edges
Edge grips for straight slab or roof slab edges have the following 6 edit modes:
- Move edge - maintain slope
- Move edge - change slope
- Add new edges - maintain slope
- Add new edges - change slope
- Convert to arc - maintain slope
- Offset all edges - maintain slope
Move edge - maintain slope
As you move the edge, adjacent edges stretch or shorten accordingly with no change to the slope. This is the default mode for straight edges.
Move edge - change slope
As you move the edge, adjacent edges stretch or shorten according to the direction of the move, and the slope changes as necessary to maintain the elevation of the edge being moved.
Side view
Add new edges - maintain slope
As you move the edge outward, rather than adjacent edges being stretched, new edges are added, each with its own Edge and Edge Overhang grips. There is no change to the slope.
Add new edges - change slope
As you move the edge outward, rather than adjacent edges being stretched, new edges are added, each with its own Edge and Edge Overhang grips. The slope changes as necessary to maintain the elevation of the edge being moved.
Convert to arc - maintain slope
Converts the edge to an arc, which you can move inward or outward in the current plane to specify the arc direction and degree. Adjacent edges are not affected.
Offset all edges - maintain slope
All outside perimeter edges move inward or outward in the current plane the same distance as you move the selected Edge grip. The degree of arc is maintained. If holes have been added to the slab or roof slab, their edges are unaffected.
Edge Grip Edit Modes for Curved Edges
For curved edges (whether originally created as such, or converted from a straight edge using the Convert to arc mode listed above), the Edge grip has 5 modes, none of which change the slope:
- Stretch edge - maintain slope
- Move edge - maintain slope
- Add new edges - maintain slope
- Convert to line - maintain slope
- Offset all edges - maintain slope
Stretch edge - maintain slope
Move the Edge grip inward or outward in the current plane to reposition the midpoint of the arc. Adjacent edges are not affected. This is the default mode for curved edges.
Move edge - maintain slope
As you move the Edge grip inward or outward in the current plane, adjacent edges stretch or shorten according to the direction of the move. The distance between the endpoints of the arc changes, but the degree of arc is maintained.
Add new edges - maintain slope
As you move the Edge grip outward in its current plane, rather than adjacent edges being stretched or reoriented, new edges are added, each with its own Edge and Edge Overhang grips. The degree of arc and the distance between the arc endpoints are both maintained.
Covert to line - maintain slope
When you click, the curved edge is converted to a straight line between the endpoints of the arc. Adjacent edges are not affected.
Offset all edges - maintain slope
All outside perimeter edges move inward or outward in the current plane the same distance as you move the selected Edge grip. The degree of arc is maintained. If holes have been added to the slab or roof slab, their edges are unaffected.
