NEW! Tutorial 22 - Three Modeling Exercises

NEW! This tutorial is about creating the geometry of a catamaran hull for high-speed ferries, a multi-concave bottom of a powerboat and the transition between struts and submarine buoyancy bodies of a Swath more


Components - Part 2

Here in Part 2 deck equipment components are shown, with which models can be given a realistic appearance. Also deck components and two other components that can be beneficial for solving certain geometry more


Components - Part 1

No design looks like the other. But boats, yachts and ships are similar. With components one can save time and effort. A component is a piece of coherent MultiSurf geometry that can be inserted into other models. Instead of creating in the work model the prefered construction for keel, rudder, deck, transom etc. each time entity by more


The Solve Set Entity

There are geometry problems that are not easy to solve. For example, construct a line that runs through a certain point and is tangent to a circle. Or you can determine the maximum width of a curve or a trunk. You can try to approximate these geometrical constructions manually, but you have to repeat them if the basic geometry changes. MultiSurf offers a permanent, fixed solution for more
