Draping images over surfaces in Civil 3D

Having recently overcome various difficulties to successfully drape an image over a surface in Civil 3D, it may be useful to pass on a few points I have learned. There are various posts and videos out there that helpfully go through this process, but some of them (including Autodesk sources) contain information that is irrelevant or just plain wrong, and none of them contained all  of the information I needed to complete the task.

I used Civil 3D 2015 for this, but the principles apply to all recent releases. Here is the basic sequence required:

  • In the drawing containing the … Full post
  • Let’s critique AutoCAD’s parametric constraints

    One of the big-ticket features of AutoCAD 2010 was parametric constraints. This was old hat for many applications, even some based on AutoCAD like Mechanical Desktop. Parametrics and constraints already existed in vanilla AutoCAD in the guise of dynamic blocks, but this was the first time ordinary AutoCAD allowed ordinary AutoCAD objects to be constrained and linked to parametric dimensions.

    Contraints mean that you can draw some objects and tell them that they are only allowed to behave in certain ways. For example, two lines have to remain parallel to each other. Parametrics mean that objects can be tied to special dimensions such … Full post

    3DConnexion device support in AutoCAD

    Do you have a 3DConnexion device (3D ‘mouse’) and use it in AutoCAD or AutoCAD-based products? What do you think of the way it works in the most recent releases of AutoCAD?

    From AutoCAD 2011 on, Autodesk provided built-in support for these devices. Has that made things better or worse than in earlier releases? If you’re having problems, exactly what are they and how does it affect your ability to work with AutoCAD in 3D? Is the 2012 support any better than 2011? How does AutoCAD’s support for these devices compare with that of other products?

    Siemens 0, Autodesk (April) 1

    Personally, I find most April fool jokes to be pretty lame. I considered doing one myself, and had what I thought was a pretty convincing idea, but finally decided against it. Maybe next year.

    This year, there was one definite exception to the lameness rule. It was well set up, clever and funny. Siemens killed it. Or, to be more accurate, they foolishly attempted to kill it. Fortunately, the Twitter CADville app is still alive and even now being tended by somebody with a fine sense of humour, as you can see from tweets like this:

    Sometimes you will … Full post

    Carl Bass on TV

    Autodesk big cheese Carl Bass gets a friendly interview on NBC’s Press:Here (amusing name, “press colon here”). It’s kind of funny seeing CAD described by non-CAD people (the presenters, not Carl). Among other things, he discusses being fired by Carol Bartz, Autodesk’s role in Avatar, the benefits of piracy, iPhones, 3D printing, open source and Autodesk being green. I’ve embedded the two Bassy bits here for convenience; these embeds will display ads that are not under my control.

    Edit: I’ve removed the embedded clips as they were slowing down this whole site for some users and even disabling … Full post

    Open Letter to James Cameron

    James, you don’t know me, but I see you have been getting involved in CAD events lately, which is my area of interest. Autodesk University 2009 attendees got a sneak preview of Avatar and you were a key speaker at Solidworks World 2010. I absolutely loved Avatar. It’s the only film I’ve ever seen where I immediately wanted to watch it again. Yes, it’s possible to poke holes in the plot, but that applies to 99% of films and anyway, this film isn’t about the plot, is it? It’s about the breathtaking visuals. I was dreaming about Pandora for days … Full post

    Guillermo Melantoni’s 3D blog

    What a Mesh is another new Autodesk blog, this time from Autodesk 3D guru Guillermo Melantoni. You may remember Guillermo mentioning his forthcoming blog in my A gaggle of geeks video, and now it has arrived. You can also see Guillermo in action in several videos about AutoCAD 2010’s new 3D mesh capabilities on AutoCAD Exchange.

    Guillermo is very, very smart, he expertly uses the products he develops (the building on the AutoCAD 2010 packaging was done by him), and it’s great to see him interacting with users in this way.
