This tutorial will describe you how I modeled my hand model from a sketch. For my other works please visit my website http://www.3d2dizayn.com/ Should you have any questions or comments, please contact me at: email@example.com The method I used here is polygonal modeling. As you can see I have a hand sketch from an anatomy book and start the modeling process using the hand sketch as a blueprint, you should do the same.
Step 1: Lets start with a circle which shown in the following picture. It doesn’t matter what you are using for modeling (it may be a box or a cylinder)
Step 2: Convert it to editable poly and Extrude. And change the parameters as you can see. Just follow the screenshots.
Step 3: Select the upper and bottom polygons and delete them. Then select the border and hold down the ShiftKey and drag it
Step 4: And scale the edges so they can match the image.
Step 5: Select the edges and click the Ring button.
Step 6: Don’t forget to check the model from all viewports. You should look left and front hand picture for reference.
