123D Design – Several Ways to Skin a Basic Cat

Greetings everyone,

Today we’re going to talk about how there is often (though certainly not always) more than one way to achieve the same or roughly the same basic shape or design using the tools available in 123D Design and how there are often several different approaches to the same task.

These different approaches may yield exactly identical results or the results they produce may differ to a greater or lesser degree and not all of them might end up doing exactly what we had planned or intended to achieve. Also, the different ways you can go about modelling the same thing may pose varying degrees of difficulty or involve different numbers of steps and each require a different amount of work and time input.

Sometimes, the best and most accurate results require the most elbow grease and time and can be the most tedious to achieve. For example, such is the case if one wants to accurately model a spiral or threading in 123D Design, which can only be done accurately using the Loft tool.

When there really is only one way to achieve exactly the desired outcome, you can generally expect to have to rely on some of the more exotic tools in the 123D Design tool set, such as the Loft or Sweep operations. For instance, the only way one can go about producing truly accurate spirals or threading (as on a bolt or nut) inside of 123D Design really only is by using the Loft operation with a high enough number of profiles as guides.

Unreal Engine 5: ‘Nanite’ and ‘Lumen’ tech on the PS5 Explained

On March 13th, Epic Games the developers of the Unreal Engine showcased a technology demo developed using Unreal Engine 5 running on the next generation PlayStation 5 console. During the short video, Technical Director of Graphics Brian Karis and Special Projects Art Director Jerome Platteaux tout several new features or technologies slated to ship with Unreal Engine 5 (of which only two would really have to do with 3D computer graphics directly) but only very lightly touch on what they actually do, never going into detail on that, and are even more tight fisted with any information at all regarding the actual implementation of the new features, how they do what they do.

Thus, we’re mainly left to speculate on what the new features are, really, and what’s driving them.

An introduction to CAD modelling with 123D Design

Hello everyone.

As one of the contributors to┬átechopsy.org’s 3D Design section, I will be endeavouring to share some of the experience and know-how I’ve accrued over the years with one of the best free CAD modelling software currently available to hobbyists who would like to start dipping their toe in the field of CAD modelling. The software in question being 123D Design, from Autodesk. The software, while free and free to use and continue to use for non-commercial purposes, has (to the best of my knowledge) unfortunately been discontinued by Autodesk, with Autodesk no longer offering it for download on their website(s) and it no longer being developed or updated by Autodesk. Indeed, the 123D Design website itself was taken down some time ago. If I remember correctly, Autodesk pulled the plug on 123D Design in 2016. Anyone who already had the software installed (or installs it afterwards using the installer downloaded from the Autodesk 123D Design website prior to the discontinuation of 123D Design) can certainly still use the software. Hopefully Autodesk will one day reconsider and revise their decision to discontinue developing and maintaining this software.

123D Design – Several Ways to Skin an Advanced Cat

Hello everyone,

Following on from where we left off with our last article but in a slightly different vein. Today we’re going to see how it’s possible to model a more challenging shape in several different ways, which each yields slightly different results.

The shape we’ll be modelling is your basic pipe segment but with triangular cut-outs extruded from its surface along its circumference. Immediately, two completely different ways of how this can be accomplished come to mind. One is additive and the other is subtractive. We can either begin with a pipe and extrude triangular cut-outs from it by different means so that we are left with the pillars in between each triangular extrusion or we can begin with nothing and just create the pillars before capping them with a top and bottom ring which can then be continued into un-extruded lengths of pipe of any desired length. We’ll go over both methods in this article.Read More »123D Design – Several Ways to Skin an Advanced Cat
