pablo scapi Posted November 24, 2009 Share Posted November 24, 2009 How to model a dodecahedron, anyone know a good and fast way? I ended up rotating and placing pentagons in a non very precise or effective way, so i´m curious on how to do it right. cheers Link to comment Share on other sites More sharing options...
easy3dsource Posted November 24, 2009 Share Posted November 24, 2009 depends on what software you're using. I have always found that 3dsmax is a pain in the neck for modeling anything with absolute precision, so usually if I don't have plans or other reference to work with, I model within rhino; you can get extremely precise results there. If you don't have a license for that, you can use AutoCad.... it is used by engineers, after all. Link to comment Share on other sites More sharing options...
Stephen Thomas Posted November 24, 2009 Share Posted November 24, 2009 Actually it's very easy with max. Create/Extended Primitives/Hedra, choose Dodec/Icos then drag the value of Q under Family Parameters up to 1. Link to comment Share on other sites More sharing options...
JonRashid Posted November 25, 2009 Share Posted November 25, 2009 Studio max can work to 23 decimal places. How accurate do you want to be? Link to comment Share on other sites More sharing options...
DanGrover Posted November 25, 2009 Share Posted November 25, 2009 Studio max can work to 23 decimal places. How accurate do you want to be? Not when you're any distance from the origin, it can't! Well, not in any useful manner. Link to comment Share on other sites More sharing options...
JonRashid Posted November 25, 2009 Share Posted November 25, 2009 that's why if your aware of the problem you don't do it Link to comment Share on other sites More sharing options...
DanGrover Posted November 25, 2009 Share Posted November 25, 2009 that's why if your aware of the problem you don't do it You often won't have a choice, for example if you're forced to work using real-world grid co-ordinates for the sake of a surveying project.

mattclinch Posted November 25, 2009 Share Posted November 25, 2009 You often won't have a choice, for example if you're forced to work using real-world grid co-ordinates for the sake of a surveying project. then offset by a set amount... Link to comment Share on other sites More sharing options...
DanGrover Posted November 25, 2009 Share Posted November 25, 2009 then offset by a set amount... Sometimes you can, but sometimes you can't, depending on contractual obligations. I know it makes no difference, you know it makes no difference, but the client rarely knows their way around a 3D programme, and it's not rare for it to be insisted that all the work occurs at the co-ords. Believe me, if there was a way around it, we'd do it! Link to comment Share on other sites More sharing options...
mattclinch Posted November 25, 2009 Share Posted November 25, 2009 wow.. so many questions Dan, i don't know where to start.. i'll start with the obvious - why should the client care if you use an offset to improve the accuracy? why are the insisting that you don't use an offset?

Nic H Posted November 25, 2009 Share Posted November 25, 2009 yeah who cares are long as it looks good sooner people learn arch vis is not about 'accuracy' (unless its a verified view) the better their work and easier time they will have. making pictures - not working drawings. first thing i do with a DWG is center it on 0.0.0 but have a snap datum and angle for when i bring in new ones.

Well that's the point, said clients aren't in it for the "prettiness", as it were, they are meant to be pin-point accurate for the sake of planning permission. It's typically used on sensitive projects where you need to explain your methodology so as to prove that the building will be where your renders say it will be. A part of this is, sometimes, that all the work has to occur on the specific OS co-ordinates, since this is where all the data will be (point data from surveyors, OS data, even the CAD data from the architect).

mattclinch Posted November 25, 2009 Share Posted November 25, 2009 ok, fair enough if thats what they are requesting. i'll only say that for the larger top end london studios handling high end planning work up to enquiry level, it is a necessary and acceptable practice to use OS offsets.

You are a beautiful person for this simple simple method of doing something I was dreading thanks for being clear, concise and to the point. Perfect.
