The section drawing
Read the to-scale section, switch between color and black-and-white, and show or hide the dew point overlay.
The middle of the screen draws the assembly to scale, with the exterior on the left and the interior on the right.
What the drawing shows #
- Each layer with its material's hatch, a lettered tag above it (A is the outermost) and its thickness below it.
- Sheet goods, like the WRB or a vapor retarder, as a line. They add no thickness.
- The overall dimension under the wall.
- The outside and inside design temperatures on either side, with the inside humidity.
Click a layer in the drawing to select it. It's highlighted in blue, along with its row in Layers. Click empty space to clear the selection.
Color or black and white #
Use Color / B/W in the toolbar:
- Color: filled layers with colored hatches.
- B/W: a print-style line drawing, with black lines and hatches on white.
The analysis overlay stays in color either way.
The analysis overlay #
Click Analysis in the toolbar to show or hide the dew point and vapor overlay. It follows the season picked in the Dew point & vapor panel, and it adds a KEY under the drawing:
- An orange line: the temperature through the wall.
- A red dashed line: the dew point.
- Green and red dots: surfaces above or below the dew point.
- Blue drops: where condensation is predicted.
- A blue dashed line: the vapor control layer.
- condensation plane: where the wall crosses the dew point.
