I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.

    I'm curious!
    I've downloaded and installed the freehand curve addon but It shows up a little different than the example in the above video! I can setup my tablet but it doesn't have the option to draw on surface! Maybe I have an older version?............

    Campbell Barton. One of those names that when you see it, you pause whatever you're doing just to check it out.

    Funny enough, I had a similar idea, using Grease Pencil drawing to convert strokes into tubes, based on a (cumbersome) makeshift system I've been using in Blender.

    But this is much better. Well-integrated into Blender. Nice adjustable options. I'm relieved!

    Good job, Campbell! Looking forward to Blender 2.78.

  3. Hi, nice addon, but i downloaded the latest build from buildbot , and the draw curve button in tools curve menu and in and add curve, appears , but are are grayed and do no let use, ignore if can be an isolated error in this compilation, and better wait for next, or i have, or i am doing something wrong .

  4. Hi Campbell,

    Really valuable addon! Thank you! One idea: how about adding an option to take the actual radius of beveled curve into account for the "offset" from a surface. (like
    offset = constant_offset + bevel_depth * vert_radius
    or similar) This way you could ensure that everything lies smoothly on the surface with minimal intersections)

    Best, Michael

    Hello Campbell!
    I really want to make use of this, but it is not showing up in the latest build of blender! I see it in the user prefs as 'active' but it wont show up in my 'create' menu. What am I missing here?
    Thank you!

  6. Hello,
    I just started using this great add-on but I am having no luck getting the Taper Radius option to work. No matter what number I enter the Start & End taper settings the curve looks the same. I'm sure I must be missing something. Thanks.
