Will Complex Models Freeze in the Browser?
It depends on how complex the model is. Complex curved surfaces, assembly motion simulation, and CAM toolpaths are outside the scope of cadAI, and that work was never meant for the browser version. Simple mechanical parts, flanged plates, and brackets are inside the scope, and those are the work cadAI is built for. No performance numbers are given in the facts card: how complex a model must be to freeze, and how much memory the browser uses, are both unlisted, so this page writes no such numbers. The judgement you can make is about scope first, and about working method second.
cadAI is a browser-based parametric CAD from Aiglade, for mechanical part modeling, hole drilling, measurement, and export, with the same kernel on desktop, in the browser, and over MCP.
- SolidCraft kernel, an independent community project, not an ArtCraft product line
- S-01 primitives, S-02 holes, S-03 conversion, S-04 measurement, S-05 preview, 5 connected intents
- Desktop, browser, and MCP, 3 forms with one kernel
- Pricing to be confirmed
What counts as complex, and what does not
Split complex into two layers: the part itself, and the way you work. The part itself is complex when it carries complex curved surfaces, an assembly, or CAM toolpaths. Those are outside the scope of cadAI, so building them in the browser is the wrong starting point, and forcing them is what freezes the work. The way you work is complex when the parameters were never settled, when detail is piled on before the rough shape is right, or when changes are made again and again without a check. That can freeze even a simple part, but the cause is the method, not the browser.
What is not complex is the work cadAI is built for: simple mechanical parts, flanged plates, and brackets, built by parameters. Set the parameters first, build the rough shape from a primitive, drill the holes, measure, preview, and export after a hand check. A flanged plate starts as a disc. Keep the browser freezing apart from the model being out of scope. A model out of scope needs a different tool, not a stronger browser.
Three kinds of choices
There are three kinds of choices, and the table shows them at a glance. This page compares categories only: it gives no version numbers, prices, or scores for any specific product.
| Choice | Install | Parametric modeling | Holes and measurement | Complex curved surfaces | AI agent drive | Who it fits |
|---|---|---|---|---|---|---|
| cadAI web version | Opens in the browser | Yes, the part follows the parameters | S-02 holes, S-04 measurement | Outside the scope | MCP interface, an agent can drive modeling | Simple parts, flanged plates, brackets, dimension checks |
| Desktop CAD | Install local software | Yes | Yes | Yes | Usually not offered | Complex curved surfaces, assemblies, CAM |
| General online tools | Opens in the browser | Mostly simple edits | Depends on the tool | Usually outside the scope | Usually not offered | Light viewing and small edits |
Choose by the part first. A flanged plate or a bracket, with no wish to install a large program, is enough for cadAI, and the parameter first method keeps the work smooth. A part with complex curved surfaces, or work needing assembly motion simulation or CAM toolpaths, belongs in desktop CAD. Opening a model to look at it once is what general online tools are for. cadAI fits mechanical engineers, makers, and 3D printing users who work on simple parts, and it does not fit work needing vendor certification and production grade accuracy sign off. Performance numbers are not given in the facts card, so no memory or speed figure is written here for any choice.
Build a flanged plate in 6 steps without freezing
Take a flanged plate as the example, and walk through 6 steps:
- Open cad.aiglade.cn in the browser, with nothing to install and no large local program needed first.
- Start a new model and set the parameters first: outline, thickness, hole count, and hole positions. Do not start drawing before the parameters are settled.
- Build the rough shape from a primitive. A flanged plate starts as a disc, and detail stays out until the rough shape is right.
- Drill the holes where they belong. Their count and position follow the parameters, so a changed parameter moves them with it.
- Measure the key dimensions: the outline and the hole positions, before 3D printing, while a fix is still cheap.
- Look at the preview, check dimensions and tolerances by hand, and only then export the model. A model must not go straight to production.
Step 2, setting the parameters first, is the one most often skipped by mistake. Drawing before the parameters are settled means changing them again and again, and that repeated change is what makes simple work feel slow. With the parameters settled, the rough shape, the holes, and the measurement follow in order, and a simple part in the browser stays smooth. If the work still freezes after the method is fixed, look at the scope again: a part outside the scope belongs in desktop CAD, not in the browser.
Who cadAI fits, and where it stops
cadAI fits light CAD work: simple mechanical parts, flanged plates, and brackets; dimension checks before 3D printing; letting an AI agent build models through MCP; and working without a large desktop program. Its strengths are the absence of an install, the parameter first workflow, and the five connected intents that an assistant can run from one sentence. Its limits are just as clear. It builds simple parts only. Complex curved surfaces, assembly motion simulation, and CAM toolpaths are outside its scope, and work needing vendor certification and production grade accuracy sign off does not fit either. The kernel is SolidCraft, an independent community project, not an ArtCraft product line. Whether chamfer is supported is not among the five connected intents, so this page does not write it as supported.

Evidence
cadAI is a browser-based parametric CAD from Aiglade, for mechanical part modeling, hole drilling, measurement, and export, with the same kernel on desktop, in the browser, and over MCP. Its kernel is SolidCraft, an independent community project, not an ArtCraft product line. Its AI assistant takes 5 intents: S-01 primitives, S-02 holes, S-03 conversion, S-04 measurement, and S-05 preview. Complex curved surfaces, assembly motion simulation, and CAM toolpaths are outside its scope, so that work was never meant for the browser version, and performance numbers are not given in the facts card, so this page writes no such numbers, because pricing is still to be confirmed and no price, tier, or free allowance is stated anywhere in this page.
FAQ
Q: Will complex models freeze in the browser?
It depends on how complex the model is. Complex curved surfaces, assemblies, and CAM are outside the scope of cadAI, and that work was never meant for the browser version. Simple parts, flanged plates, and brackets are inside the scope, and built by the parameter first method they stay smooth. Performance numbers are not given in the facts card, so no figure is written here.
Q: How complex is too complex?
The line is written in the facts card: complex curved surfaces, assembly motion simulation, and CAM toolpaths are outside the scope, and work needing vendor certification and production grade accuracy sign off does not fit either. Flanged plates and brackets are inside the scope. Past that line, change the tool, not the browser.
Q: What do I do if the browser freezes?
Look at the method first: were the parameters settled before drawing, was detail piled on before the rough shape was right, was the model checked after each change? Fix those first. If the model itself is outside the scope, move it to desktop CAD instead of forcing it in the browser.
Not written / to verify
- Pricing is to be confirmed; no price, tier, or free allowance is written in this page.
- Button labels and click paths are not written: the site is a wasm shell with no static text to check against, so the steps stay at the workflow level and do not name a specific button.
- Performance figures are not given in facts.md: how complex a model must be to freeze, browser memory use, and model file size limits are not written here.
- Whether chamfer is supported is not written as a fact: chamfer is not among the 5 connected intents, so check the page itself.
- Export formats are not listed in facts.md: whether STL, STEP, and others are supported is to be checked on the page itself.
