iGrandDesigner

iGrandDesigner makes design easy. 

Design something cool, print it as an image (jpg, tiff or png) or export it in collada (dae) or stereolithography (stl) file formats for import into modelling or 3d printing software. 

iGrandDesigner is a spline-based freeform geometric modeller which includes a world class sketcher, full boolean operations, rounds and offsetting (optionally using true offset surfaces). Functionality ranges from very high level (creating advanced parts from sketch geometry for example) to very low level (cutting and stitching individual surfaces for example). Use the Sketcher to draw curves and profiles that you constrain (tangency, length, angle etc.) as you draw. Round part edges in seconds. Write text (which can be extruded as offset surfaces) in any available font right on 3d freeform geometry. Create hierarchies via drag-and-drop in the Outliner window. Precisely place sketches, models and hierarchies via the easy-to-use geometric constraints engine OR use the even easier, Move and Rotate mouse drag operations.
