Interactive 3D solid Preview

One part, start to finish

The complete workflow, demonstrated. All featured drawings, including the one below, are direct application outputs.

  1. 1

    Describe it

    “A 120 × 80 × 10 mm aluminium mounting plate, four M6 clearance holes 12 mm in from each corner, and a 30 mm bore in the centre.”

    Plain English, with sizes. Voice works too. So does a photo of a part or a sketch on paper.

  2. 2

    Check the 3D model

    A real solid is built, not a mesh approximation, and shown in an interactive preview. Something wrong? Say so in plain English and it rebuilds. “Make the bore 35 mm” is a valid instruction.

  3. 3

    Download what you actually need

    STEP to open in SolidWorks, Fusion or Onshape. STL to print. DXF to cut. Or a dimensioned PDF drawing: four views, measured from the solid, with a title block a shop can quote from, and a Drawing tab to add, remove and move dimensions before you send it.

The Telosolid workspace: the mounting plate prompt in the chat panel on the left, and the finished 3D solid model in the preview on the right
That sentence, and the solid it produced. The four corner holes and the central bore are real geometry, not a render.
Manufacturing drawing generated by Telosolid: front, top, side and isometric views of a 120x80x10 mm mounting plate, dimensioned, with an ISO 7200 title block
The drawing itself. Front, top, side and isometric views at 1:1, with Ø30, 4x Ø6.6 and the hole spacing measured from the solid rather than typed in.

What Telosolid gives you

Real CAD, not a mesh

You get a true solid model with exact faces and edges: the same kind of geometry SolidWorks, Fusion and Onshape work with. Open the STEP file and keep editing it there. A mesh you can only print is not the same thing.

Seconds, not an afternoon

Describing a bracket takes one sentence. Modelling it by hand takes an hour and knowing which menu the fillet lives in. Change your mind and say so. It rebuilds rather than making you start over.

From a photo or a napkin sketch

Photograph a part you need to replace, or sketch one on paper. Telosolid traces the outline and builds a clean, editable 3D model from it. Useful when the original drawing is long gone.

Text & voice to 3D model

Say the dimensions and features you want. Holes, bores, fillets, pockets, patterns and wall thicknesses, described the way you'd describe them to a colleague rather than as a feature tree.

How to write the prompt

Photo & sketch to 3D model

Upload a photo of a real part or a hand drawing. Flat parts such as brackets, gaskets, plates and panels are built directly from the traced silhouette, which is the most accurate route there is.

How to shoot the photo

STEP, STL & DXF export

STEP for CAD and machining, STL for 3D printing, DXF for laser cutters, waterjets and routers. Every DXF is projected from the real solid, so it is dimensionally correct rather than a screenshot.

Which format for which job

Dimensioned manufacturing drawings

An A3 PDF with front, top, side and isometric views, dimensioned from the solid, and an ISO 7200 or ASME Y14.100 title block, in millimetres or inches. Then adjust it in the Drawing tab: add the dimensions your shop needs, delete the rest, move labels, add tolerances and notes. Your edits are saved.

See a sheet and the editor

Change it by asking

“Make it 10 mm thicker.” “Move the holes to a 90 mm pitch.” The design is rebuilt from its own history, so a change is a change rather than a fresh guess that loses everything else. Select one part first and the change applies to that part alone, leaving the rest of the assembly exactly as it was.

How to ask for changes

It checks its own work

Every build is looked at from four sides and compared with what you asked for, and a clear mismatch is corrected before you have to spot it. Something still off? Press the eye button to attach exactly what you are looking at, and describe the problem.

How the check works

Designs made of several parts

A housing and its lid are two parts, not one lump. Each is listed by name, selectable in the viewport, and can be hidden — and every export gives you exactly what is on screen, so hiding a part leaves it out of the STL, STEP, DXF and drawing too. Check fit tells you whether two of them clash, touch or clear, and by how much.

See parts in action

Import your own STEP file

Bring in a solid from any CAD system and work with it here: see it in the viewport, pick its parts apart, check how they fit, and export the ones you need as STL, STEP, DXF or a dimensioned drawing. Its units are read from the file and stated back to you.

Importing a STEP file

Every build kept, any design shareable

Every session is saved to your account, and every build in it: reopen a part weeks later and go back to an earlier build in a click. Share a design as a view-only link — the person you send it to turns it in 3D in their browser and downloads it with a free account.

Build history and sharing

What we're building next

Not built yet
Assemblies

Whole assemblies checked at once

Check fit already tells you whether two parts clash, touch or clear. Next is the whole design in one pass: every pair checked, and the faces that are meant to mate found and confirmed, so an assembly is known to go together rather than checked a pair at a time.

Analysis

Will it hold?

Stress and thermal checks in the browser, so you find out a wall is too thin before you pay for the part rather than after.

Manufacturing

Will it print, cut or machine?

A report card for the process you have in mind — 3D printing, laser cutting or CNC — with thin walls, overhangs and tool-unfriendly corners highlighted on the model before you send it out.

Common questions

Is this real CAD, or just a 3D print file?
Real CAD. Telosolid builds a solid model with exact geometry and exports STEP, which opens in SolidWorks, Fusion 360, Onshape and every other mainstream package as an editable solid. STL is offered too, but that is the mesh for printing, not the model.
Do I need to know CAD to use it?
No. You describe the part the way you would to a colleague: sizes, holes, thicknesses. The skill it removes is knowing which menu a feature lives in, not knowing what you want made.
Can I get a manufacturing drawing to send to a machine shop?
Yes. One A3 PDF with front, top, side and isometric views, dimensioned automatically from the solid, and a title block you fill in with company, drawing number, revision, material and finish. Choose ISO (first-angle) or ASME (third-angle), and millimetres or inches, to match your shop.
What does it cost?
There is a free tier with a monthly design allowance, so you can find out whether it works for your parts before paying anything.
Can it work from a photo of an existing part?
Yes. Photograph the part on a plain background and Telosolid traces its outline and builds a model from it. For flat parts such as brackets, gaskets and plates the silhouette is the shape, so that route is the most accurate one available.
Can I share a design with someone who doesn't use Telosolid?
Yes. Press Share and send the link. They see the model in 3D in their browser with nothing to install, and downloading the STL or STEP takes a free account. You choose whether they may copy it to edit, and you can turn the link off at any time.
Does it work in inches?
Yes. Describe the part in inches or millimetres, switch the 3D view's measurements between the two, and print the drawing in either: inches come out as decimal inches to three places, the way US shops read them.
Can it check that my parts fit together?
Yes. In a design with several parts, press Check fit, choose two, and it tells you whether they clash (the overlap is shown in red), touch, or clear, and by exactly how much.
