If faces are selected, then the result is a Profile Face operation. Or you can create a horizontal plane, position it at a desired elevation and generate the intersect line between the plane and hull surface. Your CAD program may have a function to do this. Give it the dimensions 100 x 10 x 2 mm (length x width x height). One trick I use to get a smooth surface is to create contour/waterlines at regular elevations on the hull surface. Hover over ‘Create a copy’ and click on ‘Refine shape’. Then select the new model and click on the ‘Part’ tab again. You don’t have to change the 0,10 value, click OK. Then click on the ‘Part’ tab and click on ‘Create shape from mesh’. If no features are selected, the command defaults to a Contour operation, contouring the entire model. Creating the model Starting with a blank FreeCAD project, we build our bimetal strip in the Part Workbench Draw a Cube Solid and rename it to aluminium. When you imported an STL file in FreeCAD, select the ‘Part’ workbench. Activate the Base Geometry section by clicking its tab, and select features from the Job model. Python can be used to analyze and process point clouds. Select the Path Profile option from the menu.Use Draft Snap Endpoint to snap to the points. Draft commands such as Draft Line and Draft B-spline can be used to connect the points in a point cloud.Merge point clouds: Creates a point cloud by combining the points of two or more point clouds.Cut point cloud: Cuts points from point clouds.Export points.: Exports a point cloud to a file.Import points.: Imports a point cloud from a file.On the panel 'Key Assignments', click on the cogs icon up right. On the start screen (aka project browser), click on the cogs icon up right, select 'User interface.Key assignments.'. Structured point cloud: Creates a structured point cloud from the points of an existing point cloud. Hello, assuming that you have an English keyboard layout and the Countour driver is installed, there's a default preset for the Shuttle in Lightwoks.Convert to points.: Creates point clouds from shape objects.Some tools are also available in the Points tools toolbar. Start by hiding the Cut feature and make the edges in the profile visible. Any 2D profile made in the Draft Workbench can be converted to an unconstrained sketch. Using a sketch is a more versatile way to create a 2D profile. The cloud of points can then be used for many purposes including building a mesh for the object, reconstructing the surfaces and solid volumes, reverse engineering, as well as for visualization and quality inspection.Īll Points Workbench tools can be accessed from the Points menu. FreeCAD provides another tool to make 2D profiles the Sketcher Workbench. ![]() A point cloud is generally produced by scanning the surface of a solid object. The workbench is still in development.Ī point cloud is a collection of points in 3D space. In this video I will show you the machining of the outer contour in FreeCAD 0.19More FreeCAD Path Videos: listPLU. The Points Workbench offers specific tools for working with point clouds.
