Record a finding on a photograph

A photograph often shows a hairline crack that the model cannot. Every place you mark on a photograph is traced through that photograph’s camera onto the model, so the finding lands on the structure at the right place.

Before you begin

Open the photograph you want to mark. See View the source photographs of a point.

To record a finding at a place on the photograph

1. In the photograph pane, click Point.

2. Click the place on the photograph.

   The New observation form opens for that point on the model.

3. Complete the form, and then click Save.

To record a finding against a rectangle

1. In the photograph pane, click Point.

2. Drag a rectangle round the defect on the photograph.

   The four corners become an outline on the model, measured as an area. The Save measurement form opens, and the status line says “outlined on the photograph — describe the finding”.

3. Complete the form, and then click Save.

All four corners must fall on the structure. If one does not, the status line says so and nothing is recorded.

To record a finding against an outline

1. In the photograph pane, click Outline.

2. Click each corner of the defect on the photograph. To pan between corners, drag the photograph.

3. To close the outline, click the first point, press Enter or double-click.

   The outline appears on the model as an area measurement, and the Measurement panel shows its figures.

4. In the Measurement panel, click Add observation, complete the form, and then click Save.

Note

Point and Outline on the photograph are the same tools as Measure ▸ Point observation and Measure ▸ Area on the toolbar. The toolbar shows which one is lit.
