Method and system for dynamically manipulating an assembly of objects in a three-dimensional scene of a system of computer-aided design

A computer-aided design system comprising;:

• a computer system;
• and
• a non-transitory computer-readable medium having computer-executable instructions that cause the computer system to dynamically manipulate an assembly of objects forming a product in a three-dimensional scene of a computer-aided design enabling design of the product, said instructions including causing the computer system to:
• provide the assembly of objects with information relative to kinematic joints linking objects of the assembly;
• provide a dynamic manipulating tool embedded in the scene, comprising a referential with three axes allowing for each axis a degree of freedom in translation and a degree of freedom in rotation;
• attach said dynamic manipulating tool to one object of the assembly;
• select a degree of freedom of the dynamic manipulating tool attached to the one object of the assembly;
• apply a load according to said selected degree of freedom based on a performed movement of associated with the dynamic manipulating tool, the performed movement of associated with the tool being converted into a load value, wherein said conversion takes into account a speed for a movement of translation according to an axis or an acceleration for a movement of rotation according to an axis or a combination of acceleration and speed to drive both rotation and translation;
• and
• calculate and display in real-time physical effects of a dynamic simulation of said load applying to the assembly of objects, in furtherance of designing the product;
• wherein said instructions cause the computer system to apply the load during the dynamic simulation based on real-time user interactions with the dynamic manipulating tool.
