Airfoils: You Are Doing it Wrong
To be fair, I was at least doing it wrong-ish for many years, or at least, not as right as I could be. Allow me to explain – and yes, I’m dusting off this blog after many years of inactivity. I figured I would get things going again by going back to the very beginning, … Continue reading
Free yourself from the insanity of Zebra analysis with Autodesk Shape
So you’re working on your surface model, and you are trying to get everything to match up nicely, usually to either G1 (tangent) continuity, or G2 (curvature) continuity. You think things look pretty good, you join them all together, you run ShowEdges to see if your model has any naked edges……and then you use Zebra … Continue reading
Why we build our surface models from scratch
Well, it’s time to dust off this blog and get it going again! It’s been way too long. Let’s just say life happens sometimes, but I’m glad to be back at this again. So, to kick off the first post, I’m going to talk about something that we spend a lot of time talking to … Continue reading
It’s Raining Software!
Well after a long blog hiatus, I’m back and happy to report there are some exciting things happening in the land of CAD. In the past few weeks there has been some very exciting news on the software front. First, out of left field, Autodesk suddenly announced it was going to resume development of T-Splines … Continue reading
T-Splines Webinar: Transitioning from NURBS to T-Splines
Well let’s get some of the dust off this blog, it’s been far too long. I’ve been busy with a variety of projects and distractions, unfortunately very little of which can be shared here. I did however do a nice one hour webinar hosted by Autodesk on the very basics of T-Splines. Especially for those … Continue reading
48″ Convair 240 – Wing Lofting
Pecking away at the Convair 240 radio control model. This is being done for a contest on the Ezone forums, and so I really need to get moving on this thing to get it in the air by June 30th contest end date. The wings are getting there – mostly lofted, just have to … Continue reading
T-Splines Tip – Panel Line Breaks
I figured I would do a quick little step by step on making panel line breaks with T-Splines. The first thing is to make sure that you have an isocurve, or isocurve loop that follows the panel line break that you want. This sometimes can be tricky – in the case of this windshield, I … Continue reading
Virtual Plastic – Porsche 962C – Main Body Complete
Franky, even I’m surprised with how well this is going. The basic body is done, and now it’s time to sub-divide the whole thing and start adding details. I was able to use tsBevel to create panel line breaks for the side windows, and a slight joggle for the windshield. This really shows me that … Continue reading
Virtual Plastic – Porsche 962C – Start of Surface Modeling
Continuing my little Tamiya Porsche 962C “virtual plastic” build, I spent a little time at the end of Friday working on the surface modeling. I started (Basil this is for you!) by projecting a line onto the front fender. Project is one of those handful of Rhino commands that works on stl meshes. There’s not … Continue reading
Giles G-200 Progress – Intersection Fairings
Moving along nicely now with the Giles G-200. I realized that before I put any more time into the cowling, I needed to have all the rest of the intersection fairings finished up. Really, the most complicated part, topologically speaking, is the intersection fairings. Since the topology of the fairings must flow into the cowl, … Continue reading
