The drawing space allows you to draw over an architectural plan after importing underlays (. PNGs) into the workspace. Once imported, a quick sequence of calibrating and setting user preferences allows for drawing thermal zones or spaces. The process is repeated for all zones and levels of the building.
Set the grid size of your Drawing in the lower ribbon. Open the dropdown menu to select the appropriate grid size, which is defaulted to 0.10 m but can be reduced to 0.01 m for detailed models.
We recommend leaving snapping on for Zones and Layers, but you can turn them off as required by toggling their respective icons.
