DRAW & VERIFY

Get the detail.
Check the fit.

Build a drawing from your site measurements, then check it against what is actually there.

GrandVerify helps you record and compare measurements. You take the readings using your own measuring equipment.

Eight example offsets locate the four corners of a skewed opening. The dashed datums cross at 90°; the top-right corner of the opening is 73.4°.

START FROM A FIXED REFERENCE

A sound datum, to capture real dimensions and angles

Set a fixed horizontal and vertical datum with laser lines or physical marks. The two lines meet at 90°. The head, sill and jambs of the opening may meet at different angles.

For a four-corner opening, take two readings at each corner: the horizontal distance from the vertical datum and the vertical distance from the horizontal datum. Those eight readings locate the corners. Take another pair wherever the edge changes direction.

DRAWING SPACE

More control over the detail.

Use the tools as the job needs them, with millimetres or inches selected in Settings.

Line drawing with reference points

Line & Measure

Work at any angle with Aligned, or choose Horizontal or Vertical for a linear measurement or line.

Parallel outline offset

Offset & Cut / Extend

Create a parallel copy of an outline, or trim and extend lines to a selected boundary.

Hole added to a drawing

Holes & curves

Record the features within the outside edge, then add the dimensions needed to check their positions.

Verify Opening in 1.3: Choose your own check points and confirm at least one measured distance. Overall dimensions are still available on drawings and exports.

THE CHECK THAT COUNTS

The drawing is only
part of the job.

  • Choose the same pointsUse Dimension Pick Points for distances you can also measure physically.
  • Compare and investigateCheck units, the datum, measurement entries and geometry if a reading differs.
  • Keep a useful recordYour verification dimensions can be included in the PDF report with Pro.

Site checks and final design decisions remain part of your professional workflow.
