You can create a volume via the New Volume button on the home page.
New volumes will be saved to the [active directory]. The active directory can be changed in the new volume dialog.
Enter a unique name for the project volume, and select the shape and dimensions for the volume. The Create button will be greyed out until a new name has been entered into the Name field. If the name already exists in the project folder, TVA will not be able to create a new volume and the Create button will be greyed out.
Rectangular
Square
Rectangle
Arch (a single curve on one side)
L-Shaped
Circular
To create an arch volume, first create a Rectangular volume. Later, truss can be [modified] to add a curve to one side.
You can choose to set the volume dimensions either by the size of the Volume, or the size of the Truss.
If you set by Volume, the truss will be 1m larger, with a gap of 0.5m.
If you set by Truss, the volume will be 1m smaller, with a gap of 0.5m.
You can modify these dimensions separately once the volume has been created by selecting Edit Volume. The dimensions will not be dependent on each other there.
