3D Modelling

We are capable of redesigning your part if necessary in order to change the raw material or technology, e.g. in the case of using additive manufacturing;

creating a CAD model:

  • from hand-drawn drawings or photos of such drawings,
  • from objects with special geometries, 
  • based on photos of objects, 
  • based on technical measurements, 
  • from a digital file created by scanning.

Briefly: In brief, 3D CAD modelling is possible with computer-aided design software that, based on mathematical calculations, digitally models the shapes the designer imagined. A 3D model on a monitor visualizes what these shapes would look like in reality.

Earlier, CAD design programmes were mainly used in the automotive industry. Although CAD programs predominantly used to be applied in the automotive industry, they have become an essential part of the manufacturing process for almost all manufacturers because CAD models of products and their components help to produce electronic (CAM) manufacturing instructions. CAD technology is so advanced that even organic shapes can be modelled.

The programs can now be applied to the following tasks:

  • Surface modelling
  • Modelling of components and sheet-metal parts
  • Installation design
  • Manufacturing drawing
  • Finite element analysis
  • Photorealistic rendering, Photorealistic architectural visualization
  • 3D printing support

Learn more about the CAD software we use in this brief introduction and be inspired to use them. In general, students, start-ups and enthusiasts can use all design software free of charge for a trial period (click here for more information).

Creating a 3D CAD model with Rhinoceros 7

Virtually any curve as well as the surfaces and solids you create can be modelled by this CAD program. It is most often used in the production of completely new prototypes. The program is non-parametric, which means sizes cannot be changed retrospectively but can only be modified simultaneously in relation to each other. More information about the features of this program can be found here: https://www.rhino3d.com/features/  

If you want to learn how to use it, I heartily recommend this page:

Design using Fusion 360

The biggest advantage is that it saves the design process parametrically, which means that by changing the previously specified dimensions, the size of the whole model is modified. For example, if it is necessary to change the size of a borehole in a model, just enter the dimensions from the drawing again. In addition, it is cloud-based so can be opened anywhere and on any computer or OS that is connected to the Internet (check the hardware requirements). In addition to CAD, CAM and CNC toolpaths for machines can be programmed using this software, which has largely contributed to the popularity of the programme.

Design on a tablet with a pencil - a brief introduction to Shapr3D

First of all, this design app, which is now used worldwide, was developed in Hungary. It is simple to use and easy to learn. Based on my personal experience, my work can be done in less than half the time by using a pencil rather than desktop software. Similarly to Rhinoceros 3D, Shapr3D is not a parametric program, that is, it does not save operations but rather stores drawings on transparencies. Its ease of use is due to the efficiency of drawing with a pencil and the facile nature of shaping a solid body with one.
