# How to model a turtle's shell starting from a circle/ using a circle?

I'm trying to model a turtle's shell. I wonder how I can start with a Circle and create the shell?

• You may start with a circle with 10 vertices, model a flat patern, then inset some faces and use a proportional editing to make a plane look like a shell. It's quite simple. Give me 5 mins and I'll show you how to do it fast :). Aug 20, 2015 at 13:05
• Thank you for your answer. Where can I see the vertices? I wait.

• I see "Vertices Data" in Edit mode, right side "n"

• Meri, your question isn't clear. Could you please change the question to something like: "How to model a turtle's shell starting from a circle/ using a circle?", so people who'll be searching for an answer in future may easily find it.. Aug 20, 2015 at 16:20

Add a Circle and set its vertices number to 10.

Scale and rotate it to fit the picture using snapping tool (click on a magnet icon and set its type to Increment). Hold down Shift while rotating to do it precisely. [In this case i rotated a circle 18 degress]. Being in Edit Mode select the whole circle (A), then pres W-->Subdivide.

Delete one half of a mesh and give it a Mirror Modifier. Extrude the vertices to fit the reference image.

Apply a Mirror Modifier and then add a Subsurf Modifier. Select the outer edges and press Alt+Shift+S (with a cursor snapped to an origin point) to make them spherical.

Now set the pivot point to Individual Origins. Select the faces as pictured below, then press I and I again to inset the individual faces. Repeat the process with other faces.

Select the edges as pictured below, press G then Z. Select all edges and sharpen them using Shift+E shortcut.

Give it a proper shape using Lattice Modifier and proportional editing. Give it some thickness using Solidify Modifier.

• This is your best answer yet. Well done. An extra plus for using the lattice modifier. Aug 26, 2015 at 3:06
• This is super cool! Is there are general rule for when you should use a lattice modifier versus when you should model with proportional editing? Oct 8, 2015 at 13:08
• @ajwood I think there are no rules :). It depends on a task. I prefer using lattice modifier with proportional editing enabled at the same time :). This explosive mix gives you an ultimate control over mesh transformation. Oct 11, 2015 at 17:11
