• Geometry and Geometric Intersections: Simple geometric errors such as duplicating and or overlapping entities are automatically corrected during this check. Certain other errors such as gaps between entities or entities extending beyond each other are flagged to the user to rectify as solutions to these are designer dependent.
• View Misalignment: FlexiCheck will analyze the input drawing for view misalignment. There is an minimum tolerance ratio below which misalignment is allowed. If FlexiCheck is unable to handle this error, the user is flagged to rectify the error before proceeding with conversion.
• Feature match-up check: This validation involves checking matches between potential geometric features among the various orthographic views (if more than one view). This validation is for informational purposes only. Should a particular feature not build properly, this validation will provide more information regarding the error.

With a large number of CAD drawings still present in paper format, the first step for most companies would be to convert these drawings to a vectorized format such as DXF or DWG. This can be achieved by a process of scanning the paper drawings to a raster format such as TIFF and then run recognition software on the raster format to output vectorized drawings. These are the more common formats that store the drawings as editable lines, arcs and circles etc... along with other non-geometric information such as notes, symbols and tables etc.... For a 2D-to-3D conversion algorithm to accept such a drawing as input would necessitate separating the geometric information, which is to be converted to a 3D model, from the non-geometric information. FlexiCheck efficiently performs this operation along with the points noted in the section above. Thus almost all drawings can be handled even if it has non-geometric information present on it or even has errors in the geometric views.

The current version of FlexiCheck is integrated into FlexiDesign's 2D-to-3D conversion process; however, a stand alone FlexiCheck package will soon be available for download and can be used to check vectorized drawings.
