Conception is an important part of each project. The main task on this stage is to determine the function of device and environment of exploitation. But we don't have any formats and norms in industrial design.
You can create it like you see. Do it like you want it to be. And we will try to do what you see. It is our job!
The sketch is quick to do, but it can save a lot of time at CAD-modeling stage. Typically, it involves planning the size and the internal space, depending on the task and device internal elements.
Usually, it includes in the process of development.
All forms which you can see around and imagine into your mind we can digitalize in 3D CAD design.
Simulation can show how your product will be felt in different conditions, visualize motion (kinematics), to determine the relationship of all the design elements.
Sometimes "bugs" that we can see on the stage of simulation can save us a lot of money at the stage of production and operation.
