Nowadays bringing up to live a wonderful 3D character or creating a real-life object is possible thanks to Blender and the Model sheets. However, you need to take into account some tips when shaping your figure. So let’s learn how to model an object based on a 2D reference.
The first thing you need is to align the Model Sheets just in the middle of an axis so that when modeling, it will be easier for you to transform an object to shape it as you like. To do that, go to the main Orthographic views (Top, side, and font) and put the images where you need
Tip: set the Top Model Sheet below your object, so you can see it better when you hit 7 to go to the Top Orthographic View.
After positioning your Model Sheets, set each one in a proper size according to the values you want to maintain in your Mesh Object. Then, add a cube by pressing Shift + A and picking it from the Add Menu. You can start with any figure you want, even spheres, nevertheless, using a cube may be more straightforward since it does not have many sides.
If your model is symmetrical, you can use a Mirror Modifier to be quicker, and also remember to use the Wireframe View to observe your Model Sheet while editing. Then, adjust the cube to the guide, add Loop Cuts to move, and fix all vertices and edges you need. At first, you don’t need to be too accurate, in fact, it’s more important to create a base shape without a lot of polygons and cuts.
Don’t be afraid of using the Extrude and Inset Tool if you need to, but when you think you’re done, use the Subdivide Modifier to smooth the base shape. Then, when you start adding other details, use the Mirror modifier for those objects and select the base shape with the eyedropper in the Mirror Object option at the Mirror Modifier.
If you have a cloven in the Model Sheet that you need to make, place the edges and the vertices according to the 2D slit drawing and then use the Bevel tool to create the shape you need and Extrude in.
Alright! be patient, and confident, and add as many details as you want. Good Luck!
