The footprint of the equipment is very well preserved. Especially manual simplification is often very time-consuming because there are hardly any internal parts that can be easily removed. In principle, the open and complex structure represents the most difficult case. The following is an example of a complex assembly table that was greatly simplified by remeshing within 1-2 minutes: example remeshing 3D CAD Model of an assembly workstation in Simplygon with texture atlas Nevertheless, the external appearance is largely preserved in the generated envelope model of equipment. In practice, this means that a true remesh approach can often remove up to 99% and sometimes up to 99.9% of data. Example of automatic simplification of 3D CAD assembly workstation Ideally, small details, such as holes and screws, and even internal parts of a CAD model of factory equipment disappear. Imaginable as a tarpaulin over the boat in the picture above or a shrink wrap around vegetables in the fish department. The original geometry serves only as a reference for a highly simplified envelope model. In simple terms, remeshing is the creation of a completely new surface mesh over a very complex 3D model.

The principle of remeshing a complex 3D model is illustrated by the tarpaulin of a boat. But this is certainly still better than not having a 3D model at hand at all, isn’t it? The time saving and very strong reduction is however also bought with cutbacks in the model quality. With so-called Remesh or Shrinkwrap methods, it is actually possible to get the large data volumes of 3D CAD models automatically down to 1% or even 0.1% of the original data volume. Radically simple through remeshing instead of reduction Contents will be updated again and again in the future. The solutions presented here are selected examples and do not claim to be complete.

What are practical solutions to radically and above all automatically simplify 3D data for layout planning? For more information on why this is so important, see also the blog article on handling CAD data. This is exactly the topic of this article. Is there a way to get this model to 5 MByte by the deadline? A dilemma of time pressure and communication problems arises. It is also too late to hire a service provider and the budget for this has already been used up.

But with a simple block representation, you will not attract anyone in the current planning phase. Close to the Digital Twin and yet past it – heavyweight 3D CAD dataĪre you also sometimes annoyed in the project, if you have to load again a too complex 3D model as STEP, DWG, or OBJ into your layout? You already know that 500 MByte will not make your factory layout leaner.
