Drawing in 3D
In Leapfrog Geo, you can draw polylines to define many surfaces, including lateral extents and contact surfaces. You can also use polylines to make adjustments to surfaces and create new GIS lines.
Leapfrog Geo has two line drawing tools: a straight line tool and a curved polyline tool.
- With the curved polyline tool, click to add straight segments and click and drag to add curved segments. When generating surfaces from curved polylines, the surface tangents are created from structural disks. The curved polyline tool can be used for drawing polylines.
- With the straight line tool, add a series of nodes to define the line. When generating surfaces from this type of polyline, the lines are sampled into points and the surface tangent is implied from the plane in which it is drawn. You can use the surface and normal ribbon tools to determine the orientation of the polyline. The straight line tool can be used for drawing polylines and GIS lines.
Attempting to draw in 3D can lead to unpredictable results and so it is always best to draw in two dimensions and add depth by some other means. In Leapfrog Geo, the best way to add depth when drawing is to use the slicer, but when you draw using the straight line tool, you can also draw on other objects in the scene. Before starting to draw, it is a good idea to orient the scene and add objects to it that will aid in drawing. Do not move the scene while drawing.
