• Select "Trilateration" in the "Draw" menu
• Fill the dialog with your desired settings
• Click a first point to define the starting point of the first side of the triangle.
• Click a second point or enter a length in the VCB to define the ending point of the first side of the triangle (Inference can be used, length uses current unit if entered):
• Click a third point to define the plane of the triangle. An axis system is displayed. The red-green plane is the plane of the triangle:

• Watch the status bar and the VCB: enter the two lengths of the two other sides of the triangle, separated with a semicolon (no matter the order of the two lengths). If something is wrong with the lengths, nothing happens (in particular when there is no solution for the triangle, when you entered two lengths whose sum is less than the length of the first side). In this case, just hit "Enter" and re-enter two lengths. Once two valid lengths are entered, the four candidate triangles will be displayed as guide lines and guide points. Preview of the triangle is drawn in a color depending of its geometric plane (blue means that it is perpendicular to Z axis, for instance).

• Click on one of the four guide points to define the triangle. If you click elsewhere than on one of the guide points, nothing happens. Once a guide point is clicked, the triangle is drawn and all the geometry you set in the settings. The tool is ready to draw another triangle.

• Select another tool to escape, or hit "Escape" key to cancel.

v 1.1.0 fixes bugs.
