Add gridlines

When working with 3D models, it is useful to have a set of gridlines to navigate around. To know where to draw the gridlines, we need some references. Click here (LÄGG TILL LÄNK ATT LADDA NER "System_Lines.dwg"). 

To create gridlines we must be on a plan drawing. Open level 1.

Go to Insert - Link - Link CAD to import the DWG reference.

Find the file 'System_Lines.dwg'. To make sure that the scale is ok, change the 'Import units' to 'millimeter'. Finish with 'Open'.

The external reference will appear in the plan drawing. The next step is to create the gridlines in Revit. 

Go to Structure - Datum - Grid.

Start drawing the horizontal gridlines from top to bottom. Then draw the first vertical gridline on the left side. Change the name from '6' to 'A' by clicking on the number and continue drawing the remaining gridlines.

Since we have gridlines now, it is not necessary to have the external reference visible. Go to View - Graphics - Visibility/Graphics and select the tab "Imported Categories". Uncheck the box in front of the 'System_Lines.dwg'.

To get the name of the gridline on both sides of the line, select each line and check to box.

Now the gridlines are placed in the model and visible from all plan drawings. The last thing to do is save them to the IMPACT database. Go to IMPACT - Project - Manage Gridlines. Select one line and click on 'Link'. Repeat for all lines and finish with 'Apply'.

All gridlines are now created and saved to the IMPACT database. Go to IMPACT Project Manager and reload the model viewer. The gridlines should appear there now as well.

The preparation of the model is now done, and the next step is to start drawing some elements. We will start with the walls in the next chapter.
