Your client opens a link and sees the part in their browser: they turn it, measure it, section it, with no CAD licence. Invite them, and they can annotate it too.
Measure, section, annotate, compare. Whatever you place on the part stays there, attached to the version you placed it on.
Distance, diameter, radius, angle, plane to plane, center distance, face area. Or let the dimension follow: point at a hole, a face, a vertex, and it knows what to measure. Save it, and it stays on the part for everyone who opens it after you.
Slice the assembly and move the section plane, or explode it to understand how it goes together.
A note, a dimension or a capture placed on the part, a highlight on a PDF. Every mark remembers the version you placed it on.
Overlay two versions, wipe from one to the other, or show them side by side. On 3D, on DXF drawings and on PDFs.
The viewer does more than show one part at a time: it composes the assembly and checks it on the exact geometry.
Pick several parts and compose them into an assembly, or bring a component into a part that is already there. Move it, rotate it, snap it to an axis or a plane: its position is saved, and the next person opens the assembly exactly as you left it. Adding a component is a permission like any other, so grant it and your client places the part themselves.
See how rights are setRun the check: it works on the original STEP and IGES, not on the display approximation. You follow its progress component by component, and the ones that collide come back in red in the scene.
The viewer adapts to what you open: it only shows the tools that make sense for that file.
Whatever the file: versions, notes, conversations, tasks, activity log and permissions, in the right-hand panel.
Produce a dimensioned sheet from the partSix standard views plus isometric, a compass, a scale bar, in perspective or parallel.
Solid, wireframe or x-ray, depending on what you are showing.
The cursor snaps to the nearest vertex, hole center, axis or face center.
Upload a file, share a link, and let your client explore the part.
