The complete list of changes can be found in the MantisBT bugtracker FC 0.19 changelog. This is a summary of the most interesting changes. 24.13 Trails, PyTrails, Turns, pivy_trackers, and GeomaticsįreeCAD 0.19 was released on March 20th, 2021, get it from the Download page.5 Core system, App, Base, and Gui namespaces.TIN will be created with the settings that displayed right after the command started. No – if the settings have been changed, they will not be preserved. Yes – TIN will be created with the current settings. When you select Yes, the mesh will be created on a new layer TIN surface. When you select Yes in the drop-down list, it is necessary to specify the layer. The possibility to create a surface only by objects of a certain layer. If the parameter is disabled, the model will not be split, a single mesh will be created. If the triangulation model turns out to be very detailed (millions of faces), then for the possibility of further convenient work, it will be divided into several meshes. The option is available only if a mesh is selected as the resulting triangulation object. The option is available only if a mesh is selected as the resulting triangulation object.Ĭolors the faces and vertices of the mesh according to the points color. Calculates normals at the mesh vertices, resulting in a smoother mesh appearance in the Precise view. In this case, click the button to the right of the Region is not selected value and draw a polygonal area within which the triangulation will be created on the point cloud. It is used when you need to build a model not by all points, but only by a certain part. When the option is disabled, the triangulation will be created in the plane of the current view. When this option is enabled, the triangulation will be created in the XY plane of the user coordinate system. When this option is enabled, only triangles located at the mesh edges will be removed during the mesh processing. The length is specified as a percentage of the maximum edge units of the face in a triangulation model or in drawing units (based on the value of Max edge units parameters). The length value is specified in the Max edge field. Triangles with an edge length greater than the specified one will be removed. When this option is enabled, after creating the triangulation the mesh will be processed. It is convenient to use for creating a triangulation mesh over the earth's surface, automatically filtering out other objects: noises, trees, constructions, etc. ![]() Maximum error – the maximum distance in drawing units from the surface formed by the bulk of points, beyond which points will be excluded from triangulation.It is convenient to use when you know the minimum percentage of points that allows you to build a mesh of acceptable quality Percent of points number – the percent of points that will be used to create a triangulation model.The total number of points can be determined by selectin all objects of Point (or Geopoint, Block) type by which triangulation will be created. Points number – the number of points to be used to create a triangulation model.The following filtration types are possible: The created model will be less accurate, but its further processing will take less time. This accelerates the process of creating a triangulation model. This will create a mesh with fewer number of larger triangles. To do this, select Yes for the Filtrate source point option, select the type of filtration for Filter Units parameters and set the desired value in the Filter range field. You can change the number of points that will be used to build create triangulation. Solids – will create a triangulation model consisting of separate triangle objects of S olid type įaces – will create a triangulation model consisting of separate triangle objects of 3D Face type. ![]() S ubMesh – creates an object of SubMesh type without the ability to edit nodes PolyFace mesh – creates an object of Polyface mesh type, the nodes of which can be edited The command options are set on the Properties bar. The following objects can be created: SubMesh, Polyface mesh, Solids or 3D Faces.Ī set of points for creating a mesh can be obtained by importing from third-party formats or from a point cloud with the Explode the Cloud into Points command. The command creates a TIN (Triangular Irregular Network) surface – an irregular triangulation network by point objects represented by Points, Geopoints or Blocks. ![]() Toolbar: Create TIN > Create TIN by Points Menu: Topoplan – Create TIN > Create TIN by Points Ribbon: Topoplan – Create TIN > Create TIN by Points ![]()
