Questions & answers

It is a set of tools (a Rhino and Grasshopper plug-in, a server and apps for viewers) that brings your models into the real space, at 1:1 or scale-model size, and keeps them in sync while you work. What you change in Rhino or Grasshopper appears in the viewer, and what you move in the viewer goes back to Rhino. More in How it works.

With the Meta Quest 3 (mixed reality, hands free or with controllers), with Android phones compatible with ARCore (augmented reality; tested on a Samsung Galaxy S24 Ultra) and with a web viewer on the computer, without mixed reality. There is currently no version for iPhone or iPad.

Rhino 8 for Windows (8.35 or newer) with the E-SPACE plug-in, a viewer (Quest 3 or an Android phone) and the computer and the viewer on the same Wi-Fi network. You also need your own Rhino 8 license: E-SPACE does not include it.

Not for now: the plug-in is for Rhino 8 on Windows.

This website is in Spanish and English. The Quest and phone apps are currently in Spanish only; English would be the first language we add (see what's next).

In three ways: with QR markers printed and stuck on the site (the most accurate), by hand, tapping with the controller or your finger the real corners of those same markers, or resting it on the floor or a table, without markers. See how each one is done.

It depends on how many markers you use and where you put them. As a guide, to ask for ±1 to 2 cm you need about one QR every 1.5 to 2 m on the wall itself, placed with a tape measure or laser. In a test with 5 widely spaced QR codes the error was 4 to 8 cm. The maps and indicators are an accuracy model, not a measurement. Details in How it works.

With one the position is fixed but the rotation is not corrected; with two or more the model is oriented and stays at 1:1; with three or more the local error goes down because the three closest to where you are are used.

The EsMarkerPrint command builds an A4 sheet with the QR codes of your model's markers. Print it at real size (150 mm per side) and stick them on the same points in the real place.

Yes. You can rest the model on the floor or a table and choose the scale (from 1:1 to 1:100), ideal for scale models. For a wall or a building site, markers give much more accuracy.

No. That is why the Wireframe and Edges views exist: they show only the outline and let you see the real thing behind.

Yes. Next to every slider, toggle, list or button there is a small E-SPACE square: when on, that parameter appears in the viewer's Param tab, with arrows, a slider and a numeric keypad. Grasshopper recalculates and the model changes instantly. Editing parameters is a Pro plan feature (included in the beta's trial month).

If your definition uses Breps, Grasshopper's recalculation can take about a second. It is best to convert to meshes before the Sync Geometry and simplify the definition.

With about 4000 pieces the phone's memory is tight. We have not yet measured the limit on the Quest; grouping fixed pieces into a single mesh is planned (see what's next).

Only the ones you allow: in the Sync Geometry component you check Move, Rotate and/or Scale. With nothing checked the piece stays fixed, which is normal for closed walls and installations. Selecting or tapping a piece does not depend on being able to move it.

No. They go from your computer to your viewers and are not kept on any server. It is explained in the privacy policy.

Only to read QR codes (the session one and the anchoring markers) and, on the phone, to show the space in augmented reality. It is processed on the device and is not stored or sent.

A connection is needed to verify your account when you open a session. Between Rhino and the viewers, data travels over your local network.

No advertising or analytics cookies. We only remember your language in your own browser and, if you fill in a form, we use what you enter to answer you. The detail is in the privacy policy.

Nothing is charged during the beta. Prices are not defined yet and appear as “on request”. The Basic plan is free. See the plans.

People who join by invitation use Pro for one month from their first sign-in. After that they move to the free Basic plan. Request access.

Nothing: your Rhino and Grasshopper models are yours and we never store them. The only thing that changes is which features you have in the viewer.

Yes, and we are building them. A faculty can have a classroom plan with many seats, and students can start on the free Basic plan. See the education page.

We do not give dates until they are tested. Today the Quest app is tested through a private Meta channel, and publishing it in the store is planned. See what's next.

First look at the troubleshooting. If it continues, write to us telling us which viewer and version you use, what you were doing and what happened; a screenshot or short video helps a lot.
