Higher Thematic Presentations

9:38 pm on the 6th of May, 2008

This year at Ross High we’re hoping our Higher Graphics Class will be producing some really cool stuff for their Thematic Presentations (a folio of different types of graphic work based around a single artefact) with a suggested theme of Lego toys. To get them started I’ve modelled a wee man with the intention that they can use him in their own work - with modifications of course.

For the course they will need to do a series of manual and computer generated drawings. One way of doing the computer drawings is to actually model the object in 3D like I’ve done above then get very accurate and detailed drawings generated from that. I’ve used Autodesk Inventor but if you want a shot of doing something similar yourself then Google Sketchup is a free programme that does similar things and comes highly recommended for all abilities.

What you see above is me just going that little bit further so that the class can see what is possible outwith the requirements of the course, animations are a fantastic way of really showing off a piece of work and can be quite good fun to make - unfortunately they aren’t currently assessed/assessable.

This example needs a lot of tidying up, but it is just a little bit of fun and (I think) quite cute.

Incidentally this took me around 2 hours to model and a further 1 at most to set up and tweak the animation. The bit that took the time was rendering the animation, around 450 frames, which took about 60 minutes for 30s of animation.

Basic Introduction to Autodesk Inventor

2:36 pm on the 24th of March, 2008

I’ve put together a wee tutorial on using Autodesk Inventor. I’ve been using the Professional 2008 version but most of it transfers across to other versions.

It is based around a series of screenshots hosted in a set on flickr with supporting notes. It works really well if you click through the set image by image. This is the first screen.

Flickr’s slideshow transitions mean that it is pretty slick when you watch it that way, although the notes added on top of the images don’t show - anyone know of a way around this other than editing the images themselves?

I’d love to know what people think of it, it was only a couple of hours work but would be nice to know I’ve not wasted that time.

Using Flickr in the classroom

8:52 pm on the 2nd of October, 2007

I’m hoping to use flickr tomorrow - it may not work depending on the school’s internet connection. The lesson will be an exercise introducing Assemblies in Inventor, a 3D modelling package. I’ve put together a few screenshots of the exercise the class are to do and then given instructions alongside them in a new photoset in flickr. Just so you can share in the joy of learning about constraints I’m going to make it all available here. I’ll make the files needed available here too and also put together a powerpoint with the images in case you can’t access flickr at your school.

Here is the flickr set, it’ll work best if you view it as a slideshow.
Here are the Inventor Parts you will need.
Here is the powerpoint in ppt format.

I’m also going to make the photos open for comments and notes and encourage my class to make use of that - will they take up the chance of an audience? (unfortunately I think it might only be a few as it requires them to be a flickr member - boo!)

3D Modelling challenge

4:50 pm on the 26th of August, 2007

Ewan bookmarked a link to some Escher inspired Lego models today which I enjoyed looking at and reading about, I found my way from there to the official Escher website which features fly-throughs of some of his work.

It got me thinking…

How long would it take a pupil to create something like the movie above? The S1s on Islay are making stuff just as good using Google Sketchup, and it took me about 2 minutes using Inventor to make the impossible triangle below, so, who’s up for the challenge?

Chris Munro - BRINGING PRODUCT DESIGN TO LIFE USING 3D MODELLING

9:25 pm on the 17th of June, 2007

Chris Munro is a teaching fellow at the Aberdeen University Faculty of Education, involved with their equivalent of Glasgow Uni’s BTechEd. Until fairly recently he was still teaching in tech departments, he is also involved with the SQA.

I think time was getting a little tight so not the presentation it might have been.

The majority of the presentation was an overview of how Inventor and other modelling software can be used with the Product Design course. He worked through the three units and referenced the work he was showing against the Arrangement Documents. Starting off by explaining that when the course was being put together initially there was a vocal minority who wanted to make 3D modelling a much bigger part of the course than it is, they were challenged by the majority, including those representing industry. This formed the basis for his presentation - that Product Design has to be about creative design and not using fancy tools to create good presentation images.

Some of his examples of pupil work showed this brilliantly, the one that stood out to me was a sofa that had been sketched by hand, had gone through a reasonable design process, but in the final sheet of images the sofa bore very little resemblance to their other designs - presumably because they didn’t have the skills to model it as they had designed it. Somewhere along the way they or their teacher had decided that they should put in some 3d modelling because it would get them marks. It didn’t.

I don’t actually have much more to say than that, the overall presentation was pretty good - it’s nice to hear how the course was dreamt up and then to see how other teachers have interpreted the Arrangements. It was particularly useful for me as I’ve never had the chance to see Product Design being taught, it’s a big gap in my knowledge - possibly to change soon…

I didn’t take any notes for this presentation, so I’m relying on my memory and the over-riding thought is that it was fairly positive about the future by showing how not to do the course - the main point being to consider using 3D modelling to add worth to the designs rather than using it just because it’s there, I’d love to hear what other people thought.

Eddie Mack - Driving the software is a start but where to next?

2:54 pm on the 16th of June, 2007

The second presentation was from my course’s very own Eddie Mack with a talk entitled Driving the software is a start but where to next?

Eddie as I say is a teacher on the BTechEd course at Glasgow Uni, he’s taught in schools until very recently and has a speciality in graphics.

For me Eddie’s talk followed very nicely on from Steve Stott’s. The theme of it was getting started with using Inventor (or any parametric software for that matter) and moving along a spectrum of heavily led tasks to complete freedom for the learner. Eddie has delivered a great number of inservice days for teachers this year and thinks he’s hit upon a pretty reasonable order for introducing the software.

His premise was that the aim when teaching the software should be to allow the pupils to model/design anything they can dream up with little or no help, but to get to that stage quickly the pupil needs to be given a series of very heavily led tasks with specific instructions.
I’m not going to go through them blow by blow, mainly because I can’t remember them all, but it was roughly starting out by modelling some form; then adding holes; then adding dimensions/constraints; then introducing features like fillets and chamfers that can give a bit more interest.

He argued that to be truly free with using the software the key thing to understand is when and why you might need to create new workplanes, which most of the audience seemed fairly agreeable to.

This was another good presentation with lots to think about for next year. Unfortunately time was a bit short so there wasn’t chance to have much discussion afterwards, one big point though was the importance of getting away from teaching from a workbook that simply gives step-by-step instructions on how to create exactly the same object as everyone else in the class/year/school. Instead to find a way that suits you to teach the skills that allow pupils to model whatever form they can dream up. Aim to get to the stage where you can just release you class onto the PCs and let them get on with it and all of your teaching is to do with the subject rather than the software (which will change in 6 months time anyway).

Chris Munro followed up this talk and happened to have with him an example of exactly the sort of thing that bores teacher and pupils silly - a 40 page A4 booklet showing every step in how to model some artefact, allowing for no creative input from the pupil whatsoever.

I’ve got my fingers crossed that Eddie will put his slides on slideshare soon. If he does I’ll link to them from here.

Steve Stott - Creative Approaches to Design

2:53 pm on the 16th of June, 2007

First talk of the afternoon was from Steve Stott of Autodesk. Several of my year had seen Steve present a short session at a conference in Dunfermline last year, this session was an extended version of that. He has a background in engineering where he worked in workshops for around 15 years, he has also been a university teacher and a school teacher. His role now is with Autodesk - the company who make AutoCAD, Inventor, various other Computer Aided Drawing/Modelling/Manufacture products. The chances are that wherever you are you can see a product or building that was worked on in some wy with Autodesk software.

The main points throughout his talk were on trying to encourage teachers and pupils to get away from designing products by looking at existing products. To stop pupils going straight for catalogues for their inspiration. Rather to take inspiration and ideas from elsewhere and to change them into something different.

One thing that stood out for me was the superb quality of his images. He showed a huge number of drawings and photos of anything and everything, much of them at the start abstract things, beautiful shapes that could be anything. What do you feel? What emotion does this throw up? What is it? These questions so often just fall on their face in schools but with images like these the job is much easier.

He took us through a couple of products that he had designed right from the initial stages of looking for inspiration. One of which was a table top lamp which started out from images of starfish, another a toothbrush holder from images of athletes.

One theme throughout was the idea of an iterative design process rather than a simple linear approach. This is something I really agree with but is not something that easily fits into most design projects that are out in schools I have been in.
What allows such an approach in the way that Steve taught it is one of the big differences between Scotland and England - in England there is far more opportunity for computer aided manufacture (CAM). This in itself does not mean that an iterative approach couldn’t happen in Scotland but it does mean that in a project that is going to be made using CAM all the designing must be done before the manufacture starts, where as in most schools I’ve been in the design part is a folio that gets completed alongside the manufacture, thus removing most opportunities for creativity.

There was a big selection of the models he had made with classes, and a lot of images showing the designs evolving and these were pretty inspiring. They were almost all CAM made plastic models though and while they looked pretty good and showed a lot of creativity, I did feel that they were all a little too form based with not a lot of functionality. That’s perhaps a personal point of view, and maybe there were other projects that were towards the function end of the spectrum. He did take quite a bit of time talking about how he came up with the toothbrush holder and how it was made stable, but as far as I could tell (I didn’t get chance to see the model close up) it wouldn’t have been stable at all in the way he was saying. It would have been nice to see other models that had been made, ones with other materials perhaps.

I found it interesting that even though he was there with his Autodesk hat on he made very little mention of the products and showed very few screenshots of it in use with his designs. The majority of the design process that he showed us was of good old fashioned pencil renderings and annotations. This is really important because the designing is what’s important. We shouldn’t be throwing our pupils into a 3D modelling package too soon if they’d be better just drawing on paper - let their imagination be the limit to their creativity, not their ICT skills.

Bubbleshare

8:19 pm on the 29th of March, 2007

Until tonight I thought bubbleshare was just another photosharing site, then I came across this post from Pam McDowell and saw the story she had created. It is similar to flickr but it does have great potential for stories and tutorials for kids, it’s just a lot more fun than flickr.

Anyway, I spent a wee while (longer than I had hoped but there you go) making up a quick tutorial on using Inventor, a 3D modelling package. While it doesn’t go into detail about how I made the drawing it does I think show how quick and easy Inventor can be.

I think I probably broke all of the rules about good design with this tutorial, in fact I feel like the person who uses 18 different animations and sounds in Powerpoint, but it was fun, next time I’ll be more restrained :)

I was pretty happy with most of bubbleshare but it still felt a little rough around the edges, so I still prefer flickr but will definitely think about this in school.

Anyway, are you ready to see my work(!)? Here you go:

Update:Having looked at it on this page I think you’d be better seeing the slideshow on bubbleshare itself to get it full size.
