Free tool · No sign-up · Nothing to install
Specify a custom precision glass component in your browser. Build it in 3D, draft a fully dimensioned 2D engineering drawing with GD&T and a title block, then export a PDF or a DXF and send it to any glass fabricator. Free, with no account and no CAD license.
Save this code before you leave — it is the only way to recall this exact model. If you lose it, your configuration cannot be restored.
Eleven precision-glass builders: glass wafers, microfluidic chips, optical filters, ITO/FTO conductive glass, perforated and special-shaped plates, AR optical and infrared windows, CCD optical plates, beam splitters, LED/OLED cover glass, glass-bottom microplates, and a made-to-drawing custom glass builder. You set the geometry and specifications, preview the part in 3D, and submit an RFQ.
Yes. Size, thickness, shape, holes, coatings and machined features update the model live. Specification-only values such as tolerances, surface quality and quantity are recorded in the RFQ summary rather than drawn.
Yes. The RFQ form accepts PDF, DWG, DXF, STEP/STP, IGES/IGS, PNG and JPG drawings. Archives and unrelated files are rejected. Your 3D configuration and specification summary are attached automatically.
No. This tool produces an engineering specification and RFQ for review; pricing is quoted separately after the engineering team confirms manufacturability.
Precision glass is quoted from a drawing. Substrate, thickness, flatness, surface quality, coating band, edge treatment and hole positions all change the price and the lead time — and a fabricator cannot infer any of them from a sketch or an email. Most labs and startups that need one custom window or one drilled substrate do not have a CAD seat to produce that drawing.
This tool closes that gap. It runs entirely in the browser, so there is nothing to download, no license and no account. You get two builders that work together: a 3D model builder to settle the geometry and the substrate, and a 2D drawing builder that produces the drawing sheet a fabricator actually needs — dimensions, tolerances, surface quality notes and a title block — which you can export as a PDF or a DXF.
Nothing you draw is uploaded until you choose to submit it. The drawing lives in your own browser, so export it before you close the tab.
This is a real drafting environment, not a shape editor. It follows the drawing standards an optics or glass fabricator expects to read.
Linear, aligned, diameter, radius and angular dimensions, with prefixes, suffixes, value overrides and tolerances. Aligned dimensions follow slanted faces and chamfers at their true angle, and every placed dimension can be dragged and stretched without changing the measured value.
Feature control frames for all fourteen ASME Y14.5 characteristics, datum feature symbols and ISO 1302 surface texture symbols — the flatness, parallelism and perpendicularity callouts precision glass is actually specified with.
ISO A4 to A0 and ANSI A to D sheets, zone markers, first or third angle projection, a default tolerance stack, revision table, item table and numbered engineering notes.
Visible, hidden, center, dimension, annotation, section, hatch and construction layers, each with its own line type, line weight, color and plot setting.
Endpoint, midpoint, center, quadrant, intersection and perpendicular snaps, inference guides on the axes and 45 degree steps, and a command line that accepts absolute, relative and polar coordinates.
A scaled PDF sheet for reading and printing, an SVG for the web, and a DXF that opens in AutoCAD, SolidWorks, Zemax-adjacent tooling, FreeCAD or any other CAD package with layers and line types intact.
Each product has its own 3D builder with the parameters that matter to it — substrate, thickness, coating, hole patterns, channel layouts. Pick one in the toolbar above.
About ten minutes end to end. If you would rather be shown, press Guide in the toolbar for a walkthrough you can skip at any point.
Select the type of component you need — an optical window, a wafer, a microfluidic chip, a coated substrate. Each one loads its own 3D model and asks only for the parameters that matter to it.
Enter the dimensions, choose the glass type — fused silica, quartz, borosilicate, soda lime, sapphire — and add holes, chamfers, coatings or channels. The transparent preview updates as you type, so the picture is a sanity check on the numbers.
Press 2D DRAWING in the toolbar to open a full drafting sheet. The title block arrives pre-filled from the product and substrate you already picked.
Draw the outline with lines, arcs, circles, splines, chamfers and fillets, then dimension it. Aligned dimensions measure slanted faces at their true angle, and diameter and radius dimensions measure the full interval with a terminator at each end.
Add GD&T feature control frames, datum symbols, surface finish symbols and numbered engineering notes, then complete the title block with the drawing number, revision, scale and projection angle.
Download a correctly scaled PDF sheet or a DXF that opens in any CAD package, or submit the specification for a fabrication review and a quote.
Scroll back up and start with the product. Export the drawing when it is done, or submit it and our engineers will review it for manufacturability and come back with a quote.
