Linea.
Draw, model, publish and render, all in the one tool.
Linea is a real modeller. Parametric walls, doors, roofs, stairs and terrain; one building held in both 2D and 3D rather than two files you have to keep in step; drawings issued at a true plotted scale, on paper, with a title block on it. It starts where the job starts, too: the surveyor's DWG goes straight in and the scheme sits on real eastings and northings from the first line. Send a view into the rendering studio when you want it rendered. It's a serious alternative to SketchUp and AutoCAD at a fraction of what either costs.
One building, two views.
Walls that know they're walls
Every element is parametric. Walls resolve their own junctions, doors carry a swing (hung the right way round), and the lot stays attached when you move the wall.
Draw in plan, work in 3D
The same building, worked on in 2D or in 3D, with typed dimensions in both. Change one; the other updates.
Let them see it for themselves
A model on a screen is still only a promise. Send a link they can walk through on their own phone, in their own time, and they turn up to the meeting having already been inside it. One click to send.
It knows what a wall is.
Walls, doors, windows, stairs, roofs, columns, floors, ceilings and lifts, each carrying the behaviour that goes with it. Levels stack into storeys. New geometry arrives in a plain painted colour, and furniture and materials come out of a library you paint on where you want them, so a scheme goes from bare blocks to something a client can read in the time it takes to pick a few finishes.
Open Linea
Start from the survey, or from a sketch.
Drop the topographical survey in as the DWG it arrived as. Linea reads the survey grid out of the file, so the scheme sits on real eastings and northings and the readout gives you E, N and metres AOD as you move over the site; the spot heights and contours become ground you can build on in one action, and anything imported afterwards lands on that same origin. Or start with nothing: trace a hand sketch and let Corb turn it into walls, drop in a real location for the surrounding buildings, or block the scheme out in Massing with real solids first.
Drawings you can actually issue.
Plans, sections and elevations at a true plotted scale, on paper from A4 to A0, with a frame and a title block. Measure a wall off the print and it's right. Save the views you keep coming back to, reissue them when the model moves, or send a perspective straight into the rendering studio. For a cover sheet diagram or a site plan that needs real vector precision rather than a plan cut, Vector sits right next to Linea in the dock, opens a plan's DXF export directly, and sends a drawing back the other way into a new Linea model.

Walk it, then hand them the link.
Step inside your own model in first person, with working doors and windows and real collision against the walls you drew. Publish that walk to a shareable link (no login, no download, laptop or phone) and hand it over. From a headset, the same walk opens in VR.
What Linea gives you.
Walls, doors, windows, furniture
Architectural objects with the behaviour that goes with them, rather than shapes you have to keep in line yourself.
Site, terrain and context
Model the ground, place the scheme on a real location, and mass the neighbours around it.
Massing you can push around
Block out a scheme with solids you can push, pull and group, then switch to the detailed walls and doors without leaving the file.
Plans, sections and sheets
Cut a section, save a view, and issue it at a true plotted scale on A4 through A0.
Walk your own model
Step inside in first person, with collision against the walls, and doors and windows that actually open.
Publish a link they just open
Share a walk with no login required. It opens on a laptop or a phone, and re-publishing over it leaves the link you already sent working. Revoking it stops the link dead.
VR when you want it
Enter the same walk from a Quest browser with no install, or a tethered desktop headset.
Skies, light and material
Real skies or your own HDRI, a time-of-day you can drag, and materials with real reflection and roughness.
Bring your own models
Import GLB, FBX, OBJ, DAE or STL straight into the drawing, or a native IFC file from Revit or ArchiCAD.
DXF both ways
A consultant's DXF comes in as editable linework, not a flat picture, and your own goes out the same way.
A calibrated underlay to draw over
Place a scanned plan or a hand sketch as an underlay and calibrate it against one known dimension, so it sits at true size to draw over by hand.
A safety net underneath it
Autosave throughout, undo behind every change, and GLB, OBJ or STL on the way out whenever the model needs to be somewhere else.
