This article outlines the software that used in conjunction with Autodesks 123D Catch can lead you to successfully creating 3 D photocopying

scanning with an ios device

 * Launch ios app
 * Guided through and take photos
 * submit photoset for 3D creation

scanning with a regular camera

 * Take photo set
 * Upload to website

scan to usable file

 * Log into website and download .STL file package
 * 3Dscanprocedure4.jpg
 * 3Dscanprocedure2.jpg
 * Install meshlab
 * Open STL and reduce the number of vertices to below 20,000 point (this is the maximum SolidWorks can import as a solid body)-
 * Example file had 608,000 faces.
 * trimming using the 'select faces in a rectangular region' tool reduced it to 100,000 faces
 * 3Dscanprocedure1.jpg
 * I then used the fill hole too so I can easily make the part a solid once it is in solidworks. this will help with making edits to the part, like reducing volume for a 3D print.
 * resampling using the Quadratic edge collapse Decimation tool, found in: filters- remeshing, simplification and reconstruction - Quadratic edge collapse Decimation brings it to 19,998 faces
 * Export mesh as .wrl file
 * Open in Solidworks - once you select to open .WRL go into the options tap and ensure solid or surface is selected rather than graphics.
 * 3Dscanprocedure6.jpg
 * for the example I then had to:
 * patch a hole
 * then I scaled
 * moved the part
 * hollowed it out
 * also it is worth changing the units to MMGS
 * 3Dscanprocedure3.jpg
 * this file can then be used in CAD as an underlay to create your new geometry, or check a fit. Or print the part to compare it to the original as a check before proceeding.
 * export the part from Solidworks as an .STL

Printing

 * Open in Formlabs build software and create the build and print or send it to a prototype house
 * PreForm
 * 3Dscanprocedure7.jpg
