3D modeling for interior designers

Specifying a custom piece usually means describing it twice: once to the client, once to the fabricator, and hoping both pictured the same thing. Arce gives you a real model to point at, early enough for it to still be cheap to change.

Where Arce fits in a design workflow

Most of the cost of a custom piece is locked in during the concept stage, when nothing exists yet except a sketch and a conversation. Modeling every direction in traditional CAD is too slow to be worth it, so studios narrow to one option early and discover the problems later.

Arce compresses that stage. You describe a piece, get an editable model with real dimensions, and adjust it while the client is still in the room. Exploring four options costs about what exploring one used to.

What you can do with it

• Model built-ins, millwork, casegoods, and loose furniture from a written description or a reference photo.
• Set real dimensions so a piece is checked against the actual opening before anyone quotes it.
• Try alternate proportions, materials, and details without remodeling from scratch.
• Present a model a client can understand, instead of a mood board they have to interpret.
• Hand your fabricator a STEP or 3DM file rather than a dimensioned sketch and a phone call.

Why the output matters

A render persuades a client. It does not tell a shop what to build. Arce produces geometry with real dimensions and exports the parametric CAD formats fabricators accept, so the file you approve is the file that gets made.

Frequently asked questions

Can I use Arce to specify custom millwork and built-ins?

Yes. That is one of the most common uses. You model the piece against the real opening dimensions, iterate on proportions and materials, then export a STEP or 3DM file your millworker can build from.

Can I show an Arce model to a client?

Yes. You can present the model directly, and export USDZ for an AR preview or GLB for a web viewer. Clients respond to a piece they can turn around far better than to a flat elevation.

Does Arce replace SketchUp for interior design?

Not usually, and it is not trying to. SketchUp is where many designers lay out a whole space. Arce is for the individual custom pieces in it, where you need a manufacturable model faster than modeling it by hand allows. Export to a shared format and use both.

What file formats does Arce export?

Arce exports STEP, 3DM, OBJ, GLB, GLTF, USDZ, STL, and 3MF. STEP and 3DM are the parametric CAD formats most shops and manufacturers ask for. USDZ covers AR previewing, and OBJ, GLB, GLTF, and STL cover rendering, visualization, and 3D printing.

Do I need to know CAD to use Arce?

No. You can describe what you want in plain language. Knowing CAD helps you push a model further once it exists, but it is not what gets you started.

How do I get access to Arce?

Arce is onboarded through a demo rather than a self-serve signup, so the setup matches how your studio actually works. Book a demo on the homepage or email support@arce.design.
