Surface to Surface
Adds a measurement showing the minimum and maximum deviation between two surfaces. This tool creates a locator showing the deviation between the two objects, labeling the minimum, maximum, and mean.
It also displays a deviation comb indicating the deviation across the length of the objects.
Objects in reference layers can be selected from within this tool.
Access this tool from the Locators palette:
Surface to Surface Deviation Options
Surface to Surface Deviation Options
Show Min / Show Max / Show Mean / Show Comb
Check/uncheck the boxes to turn the different labels and comb on or off.
The labels can also be toggled on/off from the Information Window.
Note: Starting Alias 2025.1 Update, the Max Deviation values are more accurate. Max Deviation is calculated the same way as Min Deviation, which is a true deviation calculation independent of the comb plot density. This means that the tool now produces Max Deviation values that may be different than in other versions of Alias.
When Show Comb is on, you can right-click a comb sample in the viewport to display the deviation value at that point (see Display deviation values in the viewport).
Note: Use the Min Comb Density control in the Deviation tab of the Control Panel to set the minimum increment size of the comb samples when adjusting the comb in the canvas using the middle-mouse button (MMB). See Min Comb Density (MMB).
