After opening a drawing sheet, Togal’s OCR technology (Optical Character Recognition) will automatically locate the scale written in the drawings.
However, the system does NOT test the correctness of the scale.
Therefore, you, as the user, have to always verify the accuracy of scale before proceeding with your takeoff.
How to confirm the auto detected scale:
Find two points that have a known distance between them
Select the Measure Tool
To measure the distance between two points, click on the first point, then click on the second
Confirm they match the measurement
How to set the scale manually:
Click on the scale setting in the bottom left of the drawing canvas.
Select "Set Scale Manually". There are two methods to set the scale manually.
Method 1: Draw Line method:
Find two points that have a known distance between them
Click on the first point, then click on the second
Manually enter the distance between the points
You may check the box to “Snap to standard scales”. This will convert the scale into the closest standard scale
Finally, click "Save"
Method 2: Enter Number method:
Directly enter the scale shown on the drawing
Click “Save”
Method 3: Select No Scale Needed:
Toggle from select scale manually
click "No Scale Needed"
Make sure to check that the scale is correct for each drawing. The scale might be set automatically, but it still needs to be reviewed for every drawing. You can’t manually apply one scale to the whole set, as this could lead to inaccuracies.
