SW is sluggish at best with files of this size even on a very fast machine. There's actually two different/similar ATV models (we actually scanned two different bikes) overlaying each other.įor reference, SW takes about 20Gb of ram to get these fired up, part&assy files are in the 3gb range. I am working in Solidworks with large scans. But it's enough to get you sufficient information to rebuild the part with a high degree of accuracy to the original design intent. That's your ONLY option, and it will not give you parametric, history-based models and assemblies.

In this case, the 3D software can convert this into an equivalent 3D surface set, which can then be transformed into a solid (if the data is complete). It is possible, with some data-import packages, to load up these vertex points as though they are laser-scanned "point cloud" data.

it is merely the final step before making that physical part.Įach layer consists of a series of line segments, each of which consists of two end vertices. This file format is not a CAD format, nor is it a graphics format. What is an STL file? It's basically a file which "slices" a 3D model into a series of very thin 2D "layers." This output is then used to drive a stereolithography (or similar) machine which produces physical prototypes through layer-by-layer deposition. Your best bet, if you really want to use STL to do what you're suggesting, is to get access to software designed to convert "point cloud data" into a surface. My second comment is "STL is intended to be an output file, not an input file." My first comment is "STL is not a graphics file," it's a 3D data format.

The moral of the story is STL is pretty much last choice for making a solidĪnd because it is a dense mesh of triangles some means of extracting the least complex geometry to generate a stable workable model will yield professional results. Spaced as the rate of curvature increases. Say the tibia, leg bone, the long section can be lofted with widely spaced simple splines made of a few points from the stl. Was the very natural looking and easy to manipulate. I digitized a 9 points around to generate the drive curve, 7 from the nipple down 7 from the nipple up made the along curves and swept a surface that As your human model as stl has far to many control points to process efficiently.Ī client making breast implants, laser scanned the handmade model with many thousands of points and had a team trying to manipulate the meshes. What happens is the resulting surfaces have many control points (both along and across) that are exponetially more complex and degraded.Īs a number of these poorly defined surfaces are used to construct your model process gets time consuming, inaccurate and unstable. IGES and STL files do not contain the original reference geometry to reconstruct the solid and will at the very best result in an approximation.

Deformities and round-off errors in tiny objects when a drawing contains very large objects as well as tiny objects.Basic considerations for the less experienced with cad filesĪ well constructed solid model, made up of the least complex geometric entities (lines arcs, surfaces defined by them) is ideal and stable and can be shared without degradation in a solid format (STEP, parasolid, SAT ).

Round-off errors on large coordinates such as those found in geolocated drawings.

Round-off errors on computed locations of objects, such as the locations of tangent points, and arc radiuses and their endpoints.

This loss of precision can become apparent as:

Loss of precision - PDF stores data in single precision numbers, while DWG stores data as double-precision numbers.

Refer to the Adobe documentation for more information. Set Transparency Flattening to "Print as Image" or reduce the Raster/Vector Balance in Adobe Acrobat. If the PDF file contains transparent objects, you may need to adjust some settings in Adobe Acrobat.

Printing PDF files - If you use the Adobe Acrobat Reader default printer settings to print a PDF drawing, transparent objects and wipeouts might not print correctly.

Wireframe Visual Styles - All viewports, model space or layout, that have a Wireframe or 2D Wireframe visual style applied to them are converted to path objects when exported to PDF.

Furthermore, text within the viewport is not searchable, and hyperlinks are removed. As a result, drawing information such as the layers within the viewport is lost.

3D Visual Styles - All viewports, model space or layout, that have a 3D Visual style applied to them are converted to raster images when exported to PDF.

Resolution - The highest possible resolution of PDF data is 4800 dpi.
