Swann Rack / Holocreators Switch to a side view and rotate the 3D Scan incrementally until it is aligned perpendicular to the Xaxis. Swann Rack / Holocreators Activate the checkbox “Apply incremental changes to object placement”. Swann Rack / Holocreators Click on the three dots next to the “Placement” button.

Swann Rack / Holocreators In the lower-left hand corner, click on the button “Data”. This is done in the “Sketcher” workbench. Step 2: Correct Alignment (Placement) of the 3D Scan in FreeCADĪlign the 3D Scan optimally along the X, Y and Z-axes. The reference circle sketch is now ready. So 76mm/2 FreeCAD will automatically calculate the radius ofģ8mm. Swann Rack / Holocreators Enter the radius of the diameter. Swann Rack / Holocreators Click on the button “Fix the radius of a circle or an arc”. Click on the button “Create a circle in the sketch”. Swann Rack / Holocreators Import the file “professional-3d-scan-with-artec-space-spider-tankgeber-part.stl” into FreeCAD andĪctivate the workbench “Sketcher”. Swann Rack / Holocreators The outer diameter of the flange is 75.97mm-round up to 76mm. Netfabb will automatically output the outer diameter. Swann Rack / Holocreators Select the outer edge of the flange.

The button “3 points on circle” must be activated. Swann Rack / Holocreators Click on “Measure Radius”. Swann Rack / Holocreators Click on the button “New Measuring”.

We have prepared the 3D Scan for download here. Swann Rack / Holocreators The original 3D scan is imported,”professional-3d-scan-with-artec-space-spider-tankgeber-part.stl”, In this first step, a circle is defined using FreeCAD, which will help us align the 3D scan correctly. Step 1: Measure the 3D Scan in Netfabb and create a reference sketch in FreeCAD We have prepared the CAD file for download here. Swann Rack / Holocreators After reverse engineering using parametric modeling in FreeCAD, the finished solid model (STEPįormat) looks like this. Swann Rack / Holocreators This is the original 3D Scan (STL format) of the tank sensor part.

Then, a reverseengineered 3D scan was created using parametric modeling in FreeCAD.

First, aģD scan was made using the professional 3D scanner, Artec Space Spider. As a result, STL files contain no scale information, and the units are arbitrary.The broken part, which serves as an example project, is a fuel sensor from a 50-year-old car. All STL coordinates were required to be positive numbers in the original specification, but this restriction is no longer enforced, and negative coordinates are commonly encountered in STL files today. Binary files are more common since they are more compact.Īn STL file describes a raw, unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. The STL format specifies both ASCII and binary representations. STL files describe only the surface geometry of a three-dimensional object without representing color, texture, or other common CAD model attributes. It is widely used for rapid prototyping, 3D printing, and computer-aided manufacturing.

Many other software packages support this file format. STL is a file format native to the stereolithography CAD software created by 3D Systems. The file defines object geometry and positioning and is used to render various 2D and 3D CAD designs. OpenSCAD (free CAD modeling software) is a CAD file that uses plain text formatting to store syntax written with the OpenSCAD language.
