No installation needed. Your model is processed locally and never uploaded to a server.
Dimensions and volume
Instantly see X, Y and Z dimensions, triangle count and estimated volume.
Orient for printing
Rotate and lay your model flat on a face so you can see how it sits on the build plate.
Check printability
Inspect overhangs and visualise wall thickness as a heatmap for better prints.
Measure inside the viewer
Click points, diameters or axes to measure distances accurately.
Hide parts
For multi-part models you control which parts are visible.
One viewer for all your 3D models
Instead of finding a different tool for each file format, Modelyser lets you open all common 3D printing and CAD formats. That saves time and hassle.
The viewer is designed to give you quick insight. You immediately see how large a model is, how many triangles it contains and where possible weak spots are.
Your file stays yours
Modelyser runs entirely in your browser. Your model is not sent to a server and you do not need an account. Perfect for confidential designs or a quick check without installing software.
