Issue
When editing a block or hatch in CAD, you are not seeing the Hatch Edit or Hatch and Gradient dialog boxes.
Hatch Edit dialog box
Hatch and Gradient dialog box
Cause
A system variable called HPDLGMODE is likely set to the wrong value, which is preventing these dialog boxes from displaying.
Solution
Type HPDLGMODE in the Command line, and press Enter. When prompted to enter a value, type 1 and press Enter. The hatch dialog boxes pictured above will now be able to display.
For more information on the HPDLGMODE system variable, please see the official Autodesk page on the subject.
