What is Opening Span

Opening Span (mm) is found in the Cubit Estimating Options. This option changes the way doors and/or windows openings work between two walls.

For example, if an external brick wall is measured on a plan using the external perimeter line, and the internal gyprock wall is measured on the internal perimeter line, and those two lines are 100mm apart on the plan, a door or window opening will not effectively cross both shapes if the Opening Span is set to 80mm. Changing the span size will correct this.

To access the Opening Span option:

1. In the Job Manager window, click the Cubit Estimating application button.

2. Click Options.

3. Click Jobs tab and change Opening Span field.

4. Click OK to apply the changes.

  • Is this function retro-active? Meaning, if I see that I would have to insert a door opening twice, realise that the opening span is not large enough and correct it, will Cubit then automatically insert that door into the other line?

    Or do I have to go back to the line, delete the door opening and insert the door again?
