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 surface, attach the image to your drawing using your preferred method (ImageAttach, Xref, ClassicImage). I’ll assume you’re familiar with what you need to do to get the image correctly scaled and aligned with the surface.
  • Invoke the DrapeImage command, which will show you this dialog:Full post
  • Repost – how to get your picture next to your comment

    This is a revisit of a post I made about three years ago, and repeated a year later. This has become more relevant recently because I changed the default avatars displayed next to comments to use random faces rather than random patterns. If you object to being portrayed as a grinning loon, read on.

    You may have noticed that some people’s comments have an avatar picture next to them (no, not the film with the Roger Dean visuals), while others have a randomly assigned pattern. On this blog, the avatar picture is a gravatar (globally recognised avatar), and you can have one too. Once you set it up, you will find that it works in all sorts of places, not just this blog. Some other blogs may use other avatar standards, though.

    Here’s how to do it:

  • Visit gravatar.com and pick a sign up link.

  • Gravatars – how to get a picture next to your comment

    After some recent site maintenance here, you may have noticed that the comments look a bit different, and that some people’s comments have a little picture next to them. This little picture is called a gravatar (globally recognised avatar), and you can have one too. Once you set it up, you will find that it works in all sorts of places, not just this blog.

    Here’s how to do it:

  • Visit gravatar.com and pick a sign up link.
  • Provide a valid email address; the same one you provide when adding comments to blogs. I have not received any spam as a result of doing this.
  • You’ll be sent a confirmation email; click on the link in that and follow the prompts to set your password and so on.
  • Choose your gravatar image from your hard drive, the internet, a webcam or a previously uploaded image. You can point … Full post
