The file from EinScan does not work with my CAD software?
The EinScan exports mesh data (STL.OBJ. PLY. etc…), those are composed of a large number of triangle (polygons). Traditional CAD software reads parasolid files (IGES, STEP/STP etc…), these files are composed of a set of shapes that are mathematically defined. Therefore, for CAD software a mesh is interpreted as a very large number of planes. Often the direct conversion from mesh to CAD format is limited to small files. The transformation from mesh to CAD data is called Reverse Engineering. The mesh is imported into the CAD interface and is used as a visual or matching reference for the construction of the CAD model. Solid Edge SHINING 3D edition is bundled with EinScan for this purpose. SHINING 3D has developed partnerships with multiple software companies providing Reverse Engineering solutions among them, Solid Edge, Rhino & mesh2surface, DesignX, and Geomagic for Solidworks.
How to use Markers with Handheld Rapid Scan mode?
EinScan-Pro+: Select Marker/Feature alignment. If you start the scan facing markers, markers will be required to add new data. If you start without facing markers, feature alignment is enabled. Or you can choose Hybrid alignment, the software will switch from feature to markers automatically.
EinScan-Pro: Only feature alignment is enabled. To enable Markers and Hybrid options, Rapid Registration add-on needs to be purchased.
How to scan human hair?
Hairs are difficult to scan as they reflect light in random directions, you can try to apply dry shampoo or mat color spray on the hair to turn them mat. Or do the post processing with a mesh editor. You can find some library or draw hair using 3Dmax, Maya, Blender, Z brush. These kinds of software require advanced skills.
Why other graphic cards with “higher spec” are not compatible with EinScan?
EinScan software is optimized for Nvidia GTX graphic cards. The resources allowed for scanning are different that from the ones required for CAD or gaming. The use of other cards, outside of the recommended ones, can result in the software lag or crashes.
How to scan dark objects?
Once you are at the optimal working distance, increase the brightness, until some data is captured. However, with higher brightness settings, more noise is captured. For a better result you can, prior to scanning, apply some spray on the surface: Scan spray for metrology applications, is projecting an extremely thin layer, so the shape is not affected. DIY solution: flour or baby powder can work too.
How large of an object can I scan with the EinScan Pro/Pro+?
Scanning large objects can be challenging because of the numerical limit of the software, the maximum distance in one direction(4m) and the size limit (8000*point-distance). Therefore, you reduce the resolution to achieve singular large scan data. The cumulative error is also a fact. The further you go the less accurate the data. Start from the middle of the object and follow a spider path towards the edges to reduce risk to of tracking loss. If you misalign, recovering tracking can take long as there may be multiple possibilities of matching areas. The use of markers is highly recommended for large parts. The computer capacity is a restriction too. The bigger the object, the larger the file. To improve this, register the GMF and construct the large file as a puzzle of smaller scans with a 3rd party software.
How to post process the data?
Fill more holes, erase some of the scan. EinScan software mesh editor offers Watertight or Unwatertight models, Simplification (decimate the mesh). For Unwatertight models; Fill holes respecting curvature, up to 100mm perimeter, and fill markers holes. Sharpen, smooth, brightness and contrast of the texture are theother options. For more options on these features or other features, we recommend meshlab or meshmixer (both free software) or Geomagic Wrap.
