Join Jim Cowan for an in-depth discussion in this video Use grid plan views, part of Navisworks Advanced.
- [Instructor] I want to show you how to put an AutoCAD DWG file in Navisworks that's a representation just of the grid lines. The reason I want to do this is that although there's an option inside Navisworks that lets you decide that you're going to show the grid, it doesn't show in all the views; or it only shows when your eye is in a particular position relative to those grid lines. So sometimes in real projects, people put an AutoCAD DWG so that they have a grid that they can locate so it clashes to relative to that object.
So what I want to do is, first of all, just go to the Home tab, Append. This is for the School project, so if I look at the School, Navisworks, Authoring files, 2D Grids; these are the two-dimensional DWG files that were output from Revit, and they represent different areas of the building. If you use the, from Revit, automatic name, it would be named like this, where it says floor plan and the name of the view that they are output from.
You can also, as you output them, give them any name you want. If they've been used by appending into a project, it would already have the NWC file. So I'm going to use the NWC files that I've got here. Can open them up and going to go right past this where what you see is, let me just make sure my viewpoint is shaded; these are the individual DWG files, and I'm going to do this in white so that you can see, white background.
I've got at the moment a bad choice. The grid, if I pick it, the highlight color is red. So let me go show you where it's controlled. That would be under Options and under Interface where it says Selection. If I change that for the moment to a different color, say dark blue, you see that if I pick them here, that is the grid that covered the whole model. It came from a view of the whole project.
That is just the east wing of the model, and that is maybe just the plant room floor plan with the grids exported as a DWG file; and what I want to do is I want to turn off the grids that I'm not going to use in the clash test. So I can pick them and Home Tab, Height; so I'm just seeing that portion of the building. Referring back to the options here again, that was why it was important under the file reader for AutoCAD files, DWG files, to include the settings that said convert lines.
So I'm seeing lines and convert text, so I'm seeing the text in there as well. Most of what goes wrong in Navisworks is not in Navisworks; it's in the conversion of the authoring files to be used in Navisworks. We're now ready to start doing the clash test.
