Use this procedure to edit the geometry of a mask block.
Note: If you want to replace the geometry of the mask block with newly drawn polylines, ellipses, or circles, draw them before you start this procedure.
- Select the mask block that you want to change.
- Click
. 
- If prompted that the profile is not drawn to size, click Yes.
A temporary profile is created for you to edit the geometry of the mask block.
- Note: After you perform an editing task from the Edit in Place tab, you may need to select the profile again to perform another editing task. If you do not see the editing commands that you expect on the ribbon, reselect the profile, then choose the Edit in Place command again.Edit the profile:
If you want to… Then… change the shape of the perimeter of the profile or its rings select the profile, and use edge or vertex grips to adjust the shape. The Edge grip has two edit modes: Stretch and Move. The default mode is Stretch, and the direction of the stretch depends on the orientation of edges connected to the selected edge. For example, if the edges at both ends of the selected edge are parallel, the grip edit mode is Stretch (Parallel) and the stretch direction is limited to the direction of the parallel edges. If the connected edges are not parallel, the grip edit mode is Stretch (Offset) and the stretch direction is perpendicular to the direction of the selected edge. The Move edit mode allows an unconstrained move of the selected edge. add vertices to the profile Click Edit In Place tab Profile panel Add Vertex . 
Select a point for each new vertex, and press Enter. remove vertices from the profile Click Edit In Place tab Profile panel Remove Vertex . 
Select each vertex to remove, and press Enter. replace an existing ring of the profile with new geometry Click Edit In Place tab Profile panel Replace Ring . 
Select the ring to replace, and select the new geometry. Press Enter to keep the geometry, or enter n (No) to erase it. add a ring to the profile Click Edit In Place tab Profile panel Add Ring . 
Select the geometry to define the ring. Press Enter to keep the geometry, or enter n (No) to erase it. remove a ring from the profile Click Edit In Place tab Profile panel Remove Ring . 
Select the ring to remove, and press Enter. - Save or discard the changes:
If you want to… Then… restore the mask block to its original shape Click Edit In Place tab Edits panel Cancel . 
save the changes to the current mask block Click Edit In Place tab Edits panel Finish . 
The mask block uses the edited profile to define its geometry. Any other objects or styles that use this profile are also updated with the edited geometry.
