Cambam 3d profile tutorial generator#
Leave the Heightmap generator window open and rotate and scale the CamBam drawing to get a better idea of the Heightmaps dimensions. You should see some lines appear in the underlying CamBam drawing. The heightmap heights will range from -0.125in at the deepest to 0.125in at the highest points.Ĭlose the options window and select Tools - Generate Heightmap. I have a 2d shape to limit the area of the 3d profile as it's a large model - about 1.5 meters. The heightmap heights will range from -10mm at the deepest to 0mm at the highest points. CamBam help (General usage) 3D profile tool diameter issue. This is the deepest Z depth and represents the Z coordinate of the deepest cuts in the heightmap. If the stock surface is used to zero the Z axis, then ZMax would typically be zero as well. (calculate height at each pixel in one scan line, with each horizontal scanline 0.001in apart). (calculate height at each pixel in one scan line, with each horizontal scanline 0.75mm apart) If either is set to 0, the height will be calculated at each pixel point. The YStep value controls how far apart the horizontal scan lines are and the XStep values determines how far apart each point
Cambam 3d profile tutorial series#
The bitmap will be applied to the XSize value to determine the Y height.Ī heightmap creates a series of scan lines, much the same as how a television image is created. If the YSize is set to 0, the aspect ratio of These values control the actual physical size of the resulting heightmap. Width (X) and Height (Y) of the heightmap in the same units as the current CamBam drawing. If True then darker colours are higher (larger Z values), otherwise lighter colours are higher. This three part series will step you through the design of a very simple object that uses drills and profiles. If this option is set True, the heightmap previously created will be removed before a new heightmap is generated. I have put together a video tutorial of the entire process from drawing a part in CAD (Computer Assisted/Aided Design) to the final product that is cut out from the CNC machine. The Tools - Generate Heightmap menu option from the heightmap form can be called multiple times. Here is an explanation of the properties: ClearPrevious Step 3 - Heightmap OptionsĬhange the heightmap options from the Heightmap plugin’s Tools - Options top menu. With the Heightmap generator window open, select File - Open from the top menu and select the source image. Object in blue food colouring and object with Red Filter applied.
