On an assembly drawing, Beamcore measures from axis A and 1 by default. If you work with a structural grid on site, you load it from a DWG floor plan. Beamcore extracts the grid lines, places them on the IFC model and dimensions the assembly drawings from the grid. You find the Stramien (Grid) card on the Montage (Assembly) tab of the project. This is part of the Montage (Assembly) add-on (€59 per month per licence). Everyone who sees the tab sees the grid. Anyone who may release steps may also change the grid.
Loading a DWG
- Open the Montage (Assembly) tab of the project and go to the Stramien (Grid) card.
- Choose DWG van mijn computer inladen (Load DWG from my computer) or Kies een DWG uit de projectbestanden (Choose a DWG from the project files) and click Inladen (Load). Reading can take a moment.
- Beamcore reports how many grid lines were loaded and how many fall on a wall.
The DWG is read in your browser. Only the lines, circles and short texts Beamcore needs are passed on. If a DWG cannot be read, for example because of an unsupported version or a damaged file, you place the lines yourself.
How Beamcore recognises the grid
- A grid line is a line with a bubble with text at its end. If Beamcore cannot find those, it looks at the layer name and then at long dashed lines. In that last case you get a message to check whether this is the grid.
- Only straight lines in the two main directions count. Diagonal lines are skipped. Broken lines become one line and dimensions are ignored.
- If the drawing contains several floor plans, Beamcore uses the largest.
- If a name is missing, the numbering continues, such as A, B and 1, 2.
Beamcore then looks for the position in which most lines fall on the centre or the edge of a wall. If that works well, it shows Automatisch op de wanden gezet (Placed on the walls automatically). If not, it shows Plek controleren (Check position). After your own changes it shows Handmatig gezet (Placed manually).
Setting the grid right
- Open Stramien goed zetten (Set grid right). You see the Staande lijnen (Vertical lines) and Liggende lijnen (Horizontal lines), with the Naam (Name, at most 8 characters) and the position in mm under Vanaf links (mm) (From left) or Vanaf onder (mm) (From bottom), measured from the bottom left corner of the model.
- Change a name or position, or use Lijn toevoegen (Add line) and Lijn verwijderen (Remove line). Click Opslaan (Save).
- If everything is off by some distance, fill in Alles naar rechts (mm) (Everything to the right) or Alles omhoog (mm) (Everything up) and click Verschuiven (Move). Kwartslag draaien (Rotate a quarter turn) rotates the whole grid.
Opnieuw automatisch plaatsen (Place automatically again) puts the lines back as they came from the drawing; your own changes are lost. Stramien verwijderen (Remove grid) takes the drawings back to axis A and 1. If you have no DWG, you can also place all lines yourself.
What changes on the assembly drawing
The grid replaces axis A and 1. The bubbles are at the bottom and on the left, and the zero point lies at the intersection of the first grid lines. The intermediate dimensions also run via the grid lines, and at the bottom and on the left a blue dimension line runs between the grid lines. This applies to the tab, the PDF, the Montage → Montagetekeningen (Assembly → Assembly drawings) menu and the app. Released steps always show the current grid: you do not have to release them again.
