LOOK CLOSER
The image. The shape. Every detail.
Compare each reference image with its 3D model. Rotate to inspect the shape, hidden surfaces and mesh details.
CHARACTER CONCEPTS
A character beyond the front view
Explore the mechanical legs, joints and body against the original artwork.
STYLIZED SCENES
A little world with real volume
Turn the mushroom scene around to inspect its layered shapes and hidden surfaces.
START WITH WHAT YOU HAVE
Pencil, line art, or a painted idea.
Choose the kind of drawing you have. Each gives the model different clues about shape and appearance.
Make the volume easy to read.
A three-quarter drawing can show a front, a side and the top together. Use it to explore the silhouette of a product or prop.
- What to keep
- A complete outline, visible thickness and clear separation between parts.
- Before you upload
- Crop away dimensions, arrows and other objects. Keep small parts inside the frame.
Give every part its own space.
A readable pose helps distinguish arms, legs and accessories. Simple character sketches work well as a starting point for sculpting.
- What to keep
- A clear silhouette with gaps between limbs and the body.
- Before you upload
- Remove overlapping alternate poses. Draw important accessories at a readable size.
Show the surface as well as the shape.
Color blocks and shading offer more appearance cues. A painted concept can guide a textured model while keeping your visual direction.
- What to keep
- Distinct materials, consistent lighting and one focused composition.
- Before you upload
- Simplify busy backgrounds and avoid strong shadows that hide the outline.
A BETTER START
Keep the idea. Clear up the drawing.
A readable outline gives the model more to work with. A few small adjustments can make your input easier to understand.
- 01
One object in the frame
Crop away the desk, page borders and unrelated drawings. Keep the whole subject visible.
- 02
Lines you can read
Lift faint lines with contrast. Keep checking the original so small details do not disappear.
- 03
A little depth helps
A three-quarter view shows more shape than a flat outline. Hidden surfaces will still be inferred.
WHY FOMRIX
More control between the drawing and the download.
Prepare before you spend
Crop, rotate and adjust contrast in the browser. Look at the exact image you are about to send.
Open the drawing workspaceKeep your original
Switch between the source and prepared image. Your Studio draft keeps both, so you can revisit your starting point.

MADE FOR THE FIRST DRAFT
Explore the idea before you build it.
Product concepts
Review a product's overall volume from a drawing. Exact dimensions and fitted parts still belong in a CAD workflow.
Game prop prototypes
Create a starting shape for a scene. Inspect topology, materials and scale before production use.
Sculpture ideas
Explore a character or ornament in the round. Check thin parts and mesh issues before any printing workflow.
LOOK BEYOND THE FRONT
Four checks before you call it a model.
Use this reference model to practise inspecting a mesh. Tick off each view as you explore; this is your review, not an automatic repair test.

MAKE THE NEXT ATTEMPT COUNT
Change the clue, not just the settings.
If a result misses your idea, start with the part of the drawing that is ambiguous.
| What you notice | What to change in the drawing | Next move |
|---|---|---|
| The object looks too flat | Draw a visible side or top plane. Add clear thickness instead of relying on an outline alone. | Try a three-quarter view |
| Arms or parts merge together | Leave a visible gap between overlapping pieces. Remove nearby sketches that compete with the main subject. | Simplify the silhouette |
| Tiny details disappear | Let the subject fill more of the frame. Make the defining details larger and remove secondary clutter. | Crop closer to the subject |
| Shading becomes a dark surface | Reduce heavy hatching or photographed shadows. Keep the important contour lines readable. | Check shape in clay view |

Take your model to the next step.
The right format depends on what you want to do with it.
THE MODEL IS A STARTING POINT
Keep creating after the download.
Choose your next task and follow the steps. Keep the original GLB before making a converted copy.
01
Let people see the whole idea.
Use a textured model to discuss shape, proportion and appearance with a teammate or client.
- 1
- 2
Review the important angles
Check front, side and back against the drawing. Record what needs another pass.
Use the review checklist - 3
Keep the source together
Keep your drawing and model together in Studio so you can return to the concept.

02
Take the first shape further.
Use the generated mesh as a starting point in a 3D editor. Refine topology, proportions and details for your project.
- 1
- 2
Make a geometry copy
Convert to OBJ when you need a static mesh. This conversion does not preserve materials or textures.
Convert GLB to OBJ - 3
Check the exported file
Open the OBJ to confirm its shape before continuing in your editor.
Open OBJ viewer
03
From a mesh to a checked print file.
Set a physical size and check the geometry before slicing. Conversion alone does not repair a mesh or guarantee a successful print.
- 1
Convert the geometry
Make an STL copy of the GLB and check the intended dimensions.
Convert GLB to STL - 2
Check and repair
Inspect mesh issues, repair in suitable software, then recheck the file.
Check the STL - 3
Review before slicing
Inspect the exported shape, then check supports, thin walls and layers in your slicer.

A few things worth knowing.
Can I use a hand-drawn sketch?
Yes. Photograph or scan one object in even light and save it as JPG, PNG or WebP. Keep the outline clear and the whole object visible.
Will the model match every line?
No. AI estimates depth and surfaces the drawing does not show. Small details can change. Inspect the full result before continuing your work.
Can I add a prompt to my sketch?
This workflow uses the prepared image. To generate from a written description instead, use Text to 3D. It does not combine an image and a prompt.
Is it free?
Viewing examples and preparing an image are free. Generation uses Fomrix credits. Eligible new users receive welcome credits; Studio shows the cost before you generate.
Can I print the model?
You can export STL geometry. Check its size, thin parts, open edges and sliced layers before printing. An STL file is not a guarantee of printability.
Is this CAD or an animated character?
The output is a polygon mesh. It is not a dimensioned CAD design, and it does not include automatic rigging or animation.
Your next model starts with a sketch.
