Output

DXF, DWG, 3D and SketchUp from your old building drawing

The output is made to keep working on: a drawing with a fixed structure, not a picture made of lines. Below you can read what is in each kind.

DXF · DWG

A drawing on fixed layers

Every drawing comes out the same way. That saves tidying up when you open it in your own software. The layer names follow Dutch standards and are in Dutch.

Layers named the NLCS way

A layer name is built from status, discipline, NL/SfB code, object and element. The NL/SfB code says which part of the building it is: 21 external wall, 22 internal wall, 31 and 32 the openings in them.

  • B-BK-21-BUITENWAND_METSELWERK-G external wall, geometry
  • B-BK-21-BUITENWAND_METSELWERK-A the same wall, hatching
  • B-BK-31-BUITENWANDOPENING_RAAM-S window, symbol
  • B-BK-00-ALGEMEEN_MAATVOERING-M dimensions

The first letter is the status: B existing, N new, V to be removed.

Line weights to NEN-ISO 128

The line weight is set on the layer. A wall in section is heavier than hatching or a dimension line, as you would expect on a building drawing.

0.130.180.250.350.500.701.00

The series of line weights in mm.

Hatching to NEN 47

Materials get their own hatch pattern, for example brickwork, concrete, timber and insulation. Each material sits on its own layer, so you can switch a hatch off or on in one go.

DXF directly, DWG through ODA

Vecdraft writes DXF by itself. For DWG it needs the free ODA File Converter. If that is on your computer, you get the DWG as well.

3D

3D model

Vecdraft builds a 3D model of the building from the redrawn drawings, as a GLB and an OBJ file. Vecdraft does not produce IFC yet. You can see at a glance whether the storeys line up and whether an elevation matches the floor plan.

The model is as good as the drawings it comes from. What you correct during review shows up in the model.

SKP

SketchUp file

The SketchUp file is set up the way you would do it yourself:

  • tags, so you can switch parts on and off;
  • components for the window and door frames;
  • scenes per storey and per elevation.

Open the output in your own software

The trial includes all output. Convert one of your own drawings and see whether the layers fit the way you work.
