In general, we will trace along the edges of features, either where a feature meets the ground plane or where the ground plane changes. NOTE: Creating and placing 3D polylines/curves with an accurate z-coordinate is covered in the document ‘Leica Cyclone – Creating a Mesh and Modeling Surface Topography 3D’.

Planes can be activated and edited in the RP Manager (Tools > RP > Add/Edit) There is always a plane active whether it is visible or not. NOTE: Commands are based on the active reference plane. It is comparable to the piece of paper upon which a site is drawn by conventional methods. For example, in Top View, which we will be using, all objects have their z-coordinates on this plan. In Cyclone, when using 2D Drawing Mode, the Active Reference Plane plane becomes the location along which all drawn objects are located. Create layers for primary and secondary features as needed depending on the complexity of site. Identify break lines and level of detail -> Create a new layer for the break lines (Access Layer Manager by Shift + L) and make this layer current (Highlight layer & click ‘Set Current’) -> Review the area to be modeled and identify areas where the surface changes and/or where you want a clean break or difference between adjacent surfaces. While tracing, deleting unneeded data is primarily used to clarify details being traced it becomes more important when meshing.įigure 2 – The same plaza as Figure 1 now copied to a working MS and “cleaned” of unneeded vertical surfaces and vegetation leaving only the ground plane to be modeled In the new Working MS -> -> Select and delete unneeded points: it’s best to eliminate as much vertical surface data as possible so that the ground plane to be modeled is isolated. Open a Registered Unified Model Space -> Create fence around ground plane –> Right Click –> Copy Fenced to new Model Space (NOTE: viewing from a standard side, front, or back view in orthographic mode assists in selection) -> Original MS may be closedįigure 1 – (Left) Original registered scan world of plaza (Right) Point Cloud Sub-Selection (Select -> Right Click -> Point Cloud Sub-Selection) allows unneeded points, such as trees and vertical surfaces, to be deleted Sub-selection allows the user to precisely choose and view points before deciding to delete Workflow for Tracing Topography and Site Elements – 2D: Please see ‘Lecia Cyclone: Interface Basics’ and ‘Beginner’ and ‘Advanced Workflows for Building Modeling’ for an introduction and an overview of topics not covered here. Whether creating a vector drawing or a mesh, tracing the break lines and other lines making up the site is one of the first steps.

In meshes, break lines become the edges that the triangles in the mesh conform to, defining and controlling the smoothness and continuity of the mesh. In vector drawings, break lines consist of lines, curves, and splines. Creating lines two dimensionally through tracing, is highly dependent on the user’s interpretation and basically comes down to visuallyĭefinitions: Break lines are lines or polylines that sub-divide topography into reasonably sized sections they represent the edges of a paved surface, a ridge, a channel, or any other topographic feature that the user wants to preserve. These objects can be exported and used as two dimensional drawings (for site plans or printed documentation) or as three dimensional objects (in CAD or GIS software). These geometries can be 3D or 2D, depending on how they are created.

Definitions: Vector Objects are geometrical primitives, such as lines, curves, and polygons, that can be used to represent a surface or feature. Hint: You can click on any image to see a larger version.
