A Personal Bespoke Design Story Using 3Design CAD

Recently David Law posted on his Linkedin Pulse blog a nice case study of using 3Design CAD to develop a personal bespoke design for a customer’s perfect proposal.

What’s particularly interesting about the story is how the jeweller has found a way to work around the customer’s fear of making the wrong design decision for their partner’s engagement ring.

Frequently Asked Questions 11 – What are Parametric Solid Modelling and Direct Modelling, and How Do They Apply to Jewellery CAD?

After a discussion with a colleague a few months ago, I went searching around the Internet to find a good definition of parametric history as it applies to product design CAD and jewellery CAD in particular. Unfortunately, after days of searching it appeared no one on the internet has ever bothered to explain this parametric modelling technology in layman’s terms, much less in terms relevant to a jewellery CAD designer. All my searching turned up was either very generic descriptions of parametric or direct modelling, highly technical articles from industrial engineering blogs, or salesmen selling their software without ever getting specific on technical details.

Indeed, during my research of for this article, it seems as if the most technical aspects of parametric and direct CAD modelling have been intentionally simplified to make the user interfaces more friendly for product designers. However, that did not change the fact nobody I had found had ever tried to explain what it is in a clear way before.

In an effort to solve this problem once and for all, I’ll now demystify what parametric solid modelling and its newer cousin direct modelling really are, and how they work with jewellery CAD.

Today I’d like to take a moment to talk about the commonly practised but controversial subject of combining software packages together.

Comparing 3Shaper and T-Splines for Matrix

 

Recently, we’ve started adding both T-Splines and 3Shaper to our computer courses here at Holts Academy of Jewellery. This means I’ve been spending a lot of time with both. While doing this, it occurred to me that not many other people would have the experience of working with both tools, while simultaneously not having any vested interest in selling either.

So, from this stance of neutrality, I would like to offer my evaluations of each subdivision modelling plug-in for their respective jewellery CAD software packages. Continue reading

Frequently Asked Questions Part 1 – Comparisons Of CAD Jewellery Software on the Market (Updated)

(This marks the first of a series of Frequently Asked Questions posts. See the rest of the FAQ pages.)

Over the years, the students in my CAD courses as well as my private clients have asked me a lot of questions about CAD as it relates to jewellery manufacturing. Many of these questions were often the same. As I thought it better to tailor my answer to each student’s needs, I resisted writing a single standard answer for quite a long time. Then it occurred to me that I could probably answer at least some of the questions all at once, and just fill in the gaps if people wanted to know more.

This is how this new series simply called Frequently Asked Questions began.

On this and subsequent articles in the same series, I will break down the most commonly asked questions from my own particular fields of expertise.

If anyone has any more specific questions or is not clear about something mentioned here, just leave a comment and I’ll add an answer to the entry.

For part 1, we’ll start off with the most common question of them all: “Which CAD software should I learn?”

Sharing Between CAD Programs – The Trouble With Importing and Exporting Models

I wanted to take a moment to talk about sharing.

 

…No, I don’t mean “free love”. I’m talking about the ability of different software packages to pass models and files between each other, more commonly referred to importing and exporting files. The problem is, as all of you who have worked with multiple different CAD software packages before, it is not always that easy.

It really boils down to a question of: why does there need to be so many different proprietary file formats?
