Newbie to blender here. I'm trying to take a curve or traced object and essentially make it wider all the way around. I'd also like to do the same, later but make the same object thinner all around. I'm trying to make a cookie cutter for my daughter and I want to make the object below porportionally wider, then drop a copy of it (only thinner) on top and join the objects together, this will be the "stamp" or cutting edge. Am I thinking about this correctly?

First "Layer" I want wider

enter image description here

I'd like to make the copy of this object much thinner and drop it on the top.

Thanks in advance!!!

which vertex are you referring to?

Not sure I understand you correctly, I am assuming you want a wider on top, narrower on the bottom section for the cookie cutter, one cutting side sharper edge, and one wider side to make pressure, is that correct?

If so, I'd say it would probably be easier to design the section you desire as a separate curve object, then use it as bevel object in your chicken curve.

Bevel Object

It would probably work best if your chicken was a "single stroke curve" instead of a double curve with a designed stroke width.

Otherwise if that is not possible (I see bifurcating strokes in there) you may achieve a similar effect using a "half section" instead. Just make sure the wider part of the section is always narrower than half the with of the chicken stroke to avoid self intersections and artifacts.

Half Curve Bevel


Here is an example file. Have in mind that if this is for 3D printing or other Computer aided manufacturing process, there may be geometric issues with production. Shape cleaned up and slightly altered to reduce some of the self intersections. Edit the "Chicken Cookie Cutter" object to control the shape of the section to your liking.

  • $\begingroup$ you are AWESOME! This is exactly what I'm looking to do. I created the image in illustrator and exported it as a vector image (just because I'm more familiar with Illustrator). Please excuse my lack of knowledge in Blender... I don't have the curve button (right above "3D" in your first animation) or setting you are using. Is this a plugin or something? I have the latest version of blender but it is not there. $\endgroup$

  • $\begingroup$ It is no addon, that is default blender if it is not there you might have converted your curve object to a mesh, making the curve options unavailable. If so import it again and leave it as a curve object. If the answer solved your problem consider marking it as accepted, or upvoting it if it helped you $\endgroup$ Commented Jan 12, 2017 at 1:42
  • $\begingroup$ You're right... I converted it. I'm lost at the part where it goes from double outline to 3d....Maybe I'm in over my head... I'll mark this as answered and upvote regardless! $\endgroup$

  • $\begingroup$ The difference may be that this is an image? $\endgroup$

  • $\begingroup$ That is no image, an image would not look like that when imported, I am guessing you imported this as an SVG file, if not that is what you should do. From double outline to 3D it is the exact same method as single outline above, it uses a second curve object purposefully designed to behave as section (or bevel object) on the chicken curve. Only difference is I removed half the section to suit the double stroke. Design your own to fit your purpose $\endgroup$ Commented Jan 12, 2017 at 2:06
