Issue
You're seeing the following error message when attempting to run a schedule:
Unable to reconstitute a hatch area, quantity will be inaccurate.
You may be having this issue when attempting to run a schedule, such as:
- Plant Schedule
- Concept Plant Schedule
- Reference Notes (RefNotes) Schedule
- Irrigation Schedule
- Grading Schedule
- Concept Graphics Schedule
- Zoning Schedule
Cause
This error can result from hatches that:
- Lack boundary polylines, or
- Have poorly defined boundaries
Solution
Step 1: Generate boundaries for the problematic hatches.
Look around your plan for hatches without boundaries. If you find any hatches that visibly lack boundaries, click on the pattern(s) to select the hatch(es), then right-click.
Select Generate Boundary from the menu that opens.
Determining whether a hatch has a boundary & selecting multiple hatches without boundaries
Hatches may appear to have a boundary even if they don't.
To check whether or not a hatch is linked to a boundary, select the hatch, then type PROP in the Command line and press Enter to open the Properties panel.
If the hatch's Associative setting is set to No, the hatch is not linked to a boundary.
You can use the QSELECT command to find all hatches in your drawing that are not associated with a hatch.
Type QSELECT in the Command line and press Enter. In the Quick Select dialog box, make the following selections:
- Apply to: Entire drawing
- Object type: Hatch
- Properties: Associative
- Operator: = Equals
- Value: No
- How to apply: Include in new selection set
Click OK when finished. All hatches in the drawing that are not associated with a boundary will be selected, and you can add boundaries as described above.
Also make sure that a hatch's boundary doesn't cross over itself or overlap an interior island boundary, as pictured below.
Still seeing the error when you try to run the schedule? Move on to the next step.
Step 2 (if necessary): Check whether the hatch boundary lies within an Xref or block.
A hatch boundary inside an Xref or block can also cause this issue. Use the NCOPY command to bring a line into the main drawing to connect to a hatch properly and avoid having hatches in the main drawing that are associated with lines inside blocks or Xrefs.
