AutoCAD Based Launching HydraCAD (Ribbon/Toolbar/Location)

Description:

Unable to select ceiling grid intersections when using Align Crosshairs with Ceiling

Solutions:

Cause:

AutoCAD Settings may preclude use of object snaps within hatch patterns.

Solution:

At the command prompt, type OP <enter>

Click the DRAFTING tab and uncheck 'ignore hatch objects'

Click OK

*NOTE* it is recommended this be turned on as having Acad find every osnap object in hatch patterns will slow down your drawing.  It's recommended you re-check the box after you've completed using the ceiling tiles to spot sprinklers.
