Why do we need 3D drawing files for prototype proofing? The 2D plan file or the mold of the product are not good. It can't be done without 3D drawing files, and only after looking for the model copying company to draw and copy drawings can we do the prototype.

Because 3D map is also called 3D stereoscopic map, it can see the hidden image in the map through the overlap and separation of the eye's visual imaging system. Popular speaking, it is to make use of the visual difference between people's eyes and the principle of optical refraction to make people directly see a three-dimensional picture in a plane, which can make the eye sense to see the up and down, left and right, front and back three-dimensional relationship of objects. The prototype company can more clearly understand the size, internal structure complexity and product appearance effect of the prototype made by the customer through the 3D map, judge the working hours required for the production of a prototype, and can accurately and quickly quote and deliver to the customer. At the same time, no matter CNC processing, SLA laser rapid prototyping processing or 3D printing processing, 3D graphics are required for programming. The prototype company will sign a drawing confidentiality agreement with the customer.
