Does my drawing need to be good?

No. The designer reads the intended shape, not the quality of the line. Clear views, labels and one written size matter far more than shading or perspective.

How many images can I upload?

Up to four. On Normal a concept costs 10 credits from one image and 20 from more than one; your first concept on a verified account is free. Two clear, different views usually help more than four similar photos.

Will it use the dimensions on my technical drawing?

It reads them as part of the drawing, but check every one: dimension text in a photo can be misread. Correct any size by asking, for example “make the base 12 cm wide”, or type the overall sizes in before you start.

Can it turn my sketch into a file a manufacturer can use?

Not a production file. You can export the concept as STL or OBJ (4 credits) or GLB (2 credits) and print the one-page presentation for free, but tolerances, wall thicknesses and fixings come from a CAD designer working with your manufacturer.

Turn a product sketch into a 3D concept

A sketch already holds most of the decisions about a product's shape: the silhouette, where the handle goes, how the lid sits. Upload a photo of it, up to four images, and Kubikly reads the shape you meant into an editable 3D concept with a short brief. It reads intent, not drawing skill, so a wobbly line on a napkin is fine.

Ideas you could start with

“This is a side view of a watering can for balconies; the spout should be long and thin”
“Front and side views of a small speaker; the dial on the front is the volume control”
“Whiteboard sketch of a stackable seed tray, roughly 30 by 20 cm”
“Ignore the crossed-out handle and use the one on the right”
“Technical drawing of a weekly pill organiser; the dimensions are in millimetres”

What makes a sketch easy to read

Draw what a designer needs, not what looks impressive. A front view and a side view tell more than one perspective drawing, because they separate height from width and depth. A rough perspective as a third image then shows how the parts join.

Write sizes next to the lines, with units. One real dimension, such as the overall height, anchors the rest.
Label the parts in words: lid, spout, foot, button. A circle could be a button or a hole.
Cross out what you rejected, or say in the text which version to use.
Photograph the page flat, in daylight, filling the frame, so faint lines are not lost in shadow.
Keep one product per page. A sheet of ten thumbnails will be read as one confused object.

Napkin, whiteboard or technical drawing

A napkin sketch is usually one perspective view with no sizes, so add a sentence with the dimensions you know and what the product is for. A whiteboard photo is often taken at an angle and catches reflections: stand square to the board, avoid the glare from the window, and add the same sentence.

A technical drawing with front, side and top views and dimension lines is the most precise input. Say what the units are, because a drawing in millimetres and one in inches look identical, and say which view is which if they are not labelled.

Step by step in Kubikly

Choose Upload a sketch and add up to four images, for example a front view, a side view, a top view and a detail of the lid.
Write one or two sentences about what it is and who it is for, plus anything the drawing cannot show: “the base is weighted”, “the lid twists to open”.
Optionally pick the kind of product and enter the sizes you know, in centimetres.
Compare the model with your drawing in the 3D view and the exploded view. If a part is wrong, say so: “the spout should start lower on the body”, “the handle is a closed loop, not a hook”.
When the form is right, render a Studio shot to see the sketch as a product.

Check the sizes against your drawing as you go. Anything labelled proposed is the designer's suggestion, and you can correct it by asking.

Where a sketch loses detail

The model is built from simple parts: turned silhouettes, extruded outlines, boxes, cylinders, rings and the like. That captures form, proportion and layout well, and it is why the concept can be edited. It does not reproduce fine surface detail, texture, logos or lettering from your drawing, and a sculpted, organic shape is approximated. Hidden features such as threads, clips and hinges are not modelled; they belong to the CAD stage, after the form is agreed.
