Design Display Controls

You can use various display controls to quickly navigate around the main canvas window and view your designs. For example, you can zoom, pan, or magnify a design and traverse the design hierarchy.

The following table describes the commands available on the View menu of a layout window that you can use to view and manage your designs.

Command

Description

Zoom

Controls magnification of a cellview through the following zoom commands:

  • Zoom In: Magnifies the image in the cellview window by a factor of 2. To zoom in, you can also scroll up the mouse scroll wheel.
  • Zoom Out: Reduces the image in the cellview window by a factor of 2. To zoom out, you can scroll down the mouse scroll wheel.
  • Zoom To Area: Prompts you to create a box on the canvas and then magnifies the image defined by the box to fit in the cellview window.
  • Zoom To Grid: Reduces the image to the smallest magnification at which the grid is visible.
  • Zoom To Selected: Increases the image to the largest magnification at which the selected objects can be viewed in the cellview window.
  • Zoom To Fit All: Redraws the window so that all objects in the cellview appear in the window. This saves time after you zoom or pan and want to see the entire cellview again.
  • Zoom To Fit Edit: Places the cell that you are editing in the center during edit-in-place. If you are not editing in place, Zoom To Fit Edit has the same result as Zoom To Fit All. This command is available in Layout XL and higher tiers, and not in Layout Viewer.

Magnifier

Lets you magnify or zoom a specific part of the design display area, rather than the entire design display area.

Dynamic Zoom

Pans or zooms the view automatically on the canvas based on the objects selected in the Navigator assistant.

Pan

Lets you pan a point in the center of the cellview window.

Hierarchy

Lets you descend into any level of an instance hierarchy, view the contents, and return to the desired level.

Select

Lets you select objects in full and partial selection modes. You can also set selection protection for objects.

Redraw

Refreshes the cellview display. This is helpful after you have made edits to a cellview and the design area sometimes shows portions of lines or objects that you moved or deleted.

Show Angles

Lets you display the angle enclosed at the intersection of two edges.

Show Selected Set

Displays information about a selected set of objects.

Save/Restore

Saves a zoomed or panned image to a file that lasts for the current session. You can later restore a saved view or cycle through the last three views.

Background

Lets you place an existing cellview in the background so you can place your new elements in alignment or by an offset based on the previously created cellview.

You can create rulers to measure objects and the distances between objects in a cellview. For information, see Rulers.
