The alternative to SketchUp and AutoCAD, built for how a practice actually works.
Linea is a real 2D and 3D modeller, not a viewer bolted onto a drawing tool or a drawing tool bolted onto a viewer. Parametric walls, doors, windows, roofs and stairs behave like the objects they are, the plan and the model are the same building rather than two files kept in step by hand, and a drawing issues at a true plotted scale on paper from A4 to A0. It is not pretending to be Revit or ArchiCAD. For the everyday work a small practice does, it is a serious, far cheaper alternative to SketchUp and AutoCAD, with a rendering studio, a film studio and a website builder already sitting next to it.
Model in 3D, push and pull surfaces, navigate smoothly around a scheme. Linea does that, and every object knows what kind of object it is instead of being a shape you have to keep tidy yourself.
Plans, sections and elevations at a true plotted scale, DXF in and out, a title block with a real drawing number and revision. Issue a set the way a consultant expects to receive one.
Walk the finished model in first person and publish it to a link. No export, no separate app, no install, and it works on a phone as readily as a laptop.
Draw a wall in plan and it is there in 3D. Drag a wall's height in 3D and the plan is still correct. Most software makes you choose which view is the source of truth and treat the other as a rendering of it. Here there is one building, worked on from either side.
Open LineaA separate direct-modelling workspace for blocking out a scheme and its site context with real solids: push, pull, split a face, cut a shaped hole clean through, group blocks to hide the scaffolding without deleting it. Move to Build for the detailed walls and doors once the massing has actually earned it, in the same file.
A consultant's DXF comes in as editable linework, with a layer picker so a whole survey does not land in one go. A native IFC file from Revit or ArchiCAD grafts in as real walls, doors, windows and levels, parsed entirely in the browser. Bring your own GLB, FBX, OBJ, DAE or STL. None of it needs rebuilding to be used.
Step inside the scheme in first person, with collision against the walls you drew and doors and windows that open. Publish it to a no-login link that opens on a laptop or a phone, or in VR from a headset. Revoke it or republish over it as the design changes without breaking the link already sent.
Walls, doors, windows, stairs, roofs, columns, floor slabs and lifts, with the behaviour that goes with each one, not shapes you have to keep aligned by hand.
Push, pull, split and group solids before there are walls, then move to the detailed model in the same file.
A4 through A0, with a title block carrying project, client, drawing number, revision and scale, never squeezed to fit.
A consultant's DXF or IFC comes in as editable geometry with a layer picker. Your own DXF goes back out the same way.
GLB, FBX, OBJ, DAE or STL drop straight into the drawing alongside anything built here.
First-person walk with real collision, published with no login required, working on a laptop, a phone, or in VR.
Curated skies or your own HDRI, a draggable time of day, and materials with real reflection and roughness.
Sculpt the ground, place a scheme on a real location, and pull in the surrounding context automatically.
Calibrate a scanned plan or a hand sketch against one known dimension and let Corb turn it into real walls.
