ActiveSolid is an OpenGL based 3D solid modeling, CAD prototyping and view mark-up application. It runs in either of two modes: as an ActiveX control in the Internet Explorer and as a standalone end-user application. It features an intuitive, non-blocking and customizable GUI, an import/export plug-in architecture, associative 3D dimensions (point-to-point, point-to-face, X-,Y- and Z-dimensions) for accurate model measurements, robust Boolean operations on 3D meshes and 2D polygons, 2D mark-up tools, 3D slicing for arbitrary or axis-aligned profile generation, local vertex editing on 3D meshes and 2D polygons, and an array of powerful 3D object creation tools (e.g., extrusion from complex and nested profiles, 3D polygon and mesh creation from true type fonts, and optimal mesh reconstruction from planar, non-parallel contours).

ActiveSolid is written entirely in C++/ATL/WTL and is thus very compact. All functionality is packed inside ActiveSolid.dll for just a little over 1.5mb (excluding OpenGL.dll for rendering and FreeImage.dll for 2D image import/export). It costs $29us to register. To our knowledge, it is the only high quality solid modeling and view mark-up program/control in this price range.

The new version 1.5 is now available for download. Also available as a separate download from the J&L Associates' download page are the free Q3BSP import and XGL export plug-in's (in addition to the built-in 2D and 3D importers and exporters).
