Design/methodology/approach: The three methods of the globoid surface modeling, using CAD systems - AutoCAD and CATIA were presented. The worm gear development, including these atypical ones, requires looking for new solutions in their modeling. These surfaces are modeled on the helix with uniform pitch but diameter variable only. The examples of globoid helical surfaces modeling in CAD are accessible on the Internet, but often they are not correct in terms of geometry and they do not reflect the actual geometry. Modeling of globoid worm surface can cause the problem. The software intended to model of the worm gear wheel only is not accessible, so basing on general intending CAD systems is a necessity. There are very few specialized applications to generate this type of gears. Worm gears are a challenge for designers because of the construction and the functions that have to be met, as well. Purpose: Modeling of globoid worm surface is a difficult issue of modeling of complex surfaces in CAD.
