3D reference

3D model construction is done with the union of extruded 2D sections (called "Components").

In "Lines" tab, on the top it is possible to perform simple operations on components:

• create a new one ;

• remove the current one ;

• clone the current one .

Clicking on component's name you can modify it. In "Lines" tab, just below component's name, a second one can be selected and it will be used as a snap reference.

Through "File"->"Merge" menu it is possible to add 2D projects to current component.

As 2D simulations also 3D ones require flow directions and gravity vector settings. Selecting "Use for 3D simulation" in one of the components, its settings will be used for the 3D simulation.

With reference to the X, Y and Z axes shown in the viewport, the gravity vector:

• "downward" matches negative Y axis;

• "into the screen" matches the negative Z axis.
