Start with a reliable reference
Set horizontal and vertical datum lines at 90° to one another. Keep the same datum throughout the survey. The opening itself may be out of square.
SITE GUIDE · VERIFICATION
Measure the opening.
Check the drawing.
Record opening measurements against a fixed datum, build the drawing and check key dimensions against the actual opening.
Record changes along every side
Measure from the laser or physical datum to the relevant positions along each side. A typical opening generally needs at least eight readings, with more for steps, recesses or other changes.
Connect and inspect the outside edge
Use Pick Points in Drawing Space to connect the perimeter in order. Check directions, corners and any holes or curves against the opening.
Check dimensions on the actual opening
On Verify Opening, select the points for useful check dimensions. Compare these with physical measurements between the same locations. Recheck unexpected values and correct the source before proceeding.
Keep the checks with the job
The verified drawing stays in the app. With Pro, prepare a PDF report, DXF drawing and supporting photo, then review and share them from Project Documents.
