High end 3D app filleting

Low end and mid range 3D application commonly struggle with producing proper filleting of curves. Some even mess up in performing such tasks. Even more so when fillets of different radii meet and / or surfaces join at angles other than perpendicular. High end 3D programs however have no trouble handling such matters. See image below where detail is in red circles.

EFC - Earth & Flight Composites

EFC is an enterprise that conducts training and offers consultancy for the advanced composites industry. Composite materials are increasingly applied in construction since they are strong, have a light weight and hardly require maintenance. But construction and repair activities require skills that are quite distinguished from those of traditional sheet metal work and application of other materials.

Consequently a different type of knowledge and skill are necessary to process composite materials properly. Since it is often applied in critical constructions, poor handling can lead to disastrous consequences. It is for this reason that industry authorities have decided to issue guidelines and directives. EFC is well informed concerning the knowledge and skills required to work and operate composite material constructions safely. Decades of practical experience in the business and acquired certification by attending many courses make EFC a trustworthy partner for companies seeking to train their staff or inform their management.

3D fillets

3D applications have different approaches to processing matters; the way in which their functions handle things are distinguished. The algorithms in which they calculate certain processes are different formulas. In this respect they resemble people all of whom have different talents and different things at which they suck (pardon my French). The image below is an example of the different way of handling of matters.

The fillet of the object at the top is irregular while the bottom one is smooth. It is an angled joint of two pipes of a different diameter - one of the constructions that a number of 3D programs do not handle well. The fillet actually looks like a real life weld of welder who was not too skilled. Also the fillet command disrupted the surface of the slanted pipe. The application producing the poor filleting does an excellent job at other types of modeling, rendering and creating animations, but this particular function gives bad results. It is probably why many 3D artists use various applications to achieve whatever they want to achieve.

High end applications

I have been watching a number of tutorials on Youtube on a high end 3D program - Solid Edge - and became stunned by its complexity that was paired with a user friendliness that I was unaware of. This seems to be a contradiction, but in fact it just requires the user to adapt a different frame of mind when modeling parts. What this means, is that many relations between (sub) parts exists - similar to what we encounter in every day life - that we take for grated without actually being aware of it. The complex functionality was made to serve user comfort and increase construction options dramatically, which are features never seen in the over the counter commercial apps most people have installed on their computer.
