![]() The 2D view can be independently controlled for each view. As you can see in the below image the 3D control point is automatically on the Scope box, this will control all the plan views. The Scope box will then control the setting out. Prior to creating the Scope box you should get the grids set the correct distances and basically make sure that everything is set out neatly. You then draw the Scope box around the grid and then name the Scope box and set the view properties as shown in the below image. It is recommended to use the Rotate command from the modify ribbon and not to use the in-built rotate command as this is difficult to control accurately. Unfortunately the Scope box is always a rectangular shape (Not very useful for our radial grid problem earlier), but you can rotate this once created. The Scope box command is located on the View Ribbon within the Create panel. Note that the grids and levels are quite messy the elevations. The Scope box will improve the ease of setting grids in elevation and plan and especially useful then part of the structure is rotated as shown below. Scope boxes can be useful to help control grids and levels both in plan, elevation and sections. It is worth noting that the grid cannot be controlled with a Scope Box (Covered Below). The grid is simply drawn with a series of lines and arcs and then when the sketch is finished the grid is created. I also create a detail line to help set the grids out as shown below.Ī new feature of Revit 2013 is the ability to create a continuous grid line with the same reference called a multi-segment grid. ![]() I create a new section type called grid control which helps when you need to hide these section marks. The only solution I have found is to create a sectional view that is perpendicular to each grid. This is because the grids need to be elevated to cut through the levels and a grid is not shown unless a view is perpendicular to the grid as shown in the image below. The first issue you will find is that the grids will not show on new levels. When working with Radial grids you will typically find a couple of problems. You then select the views to match to the original. Select all the grids on the correct level and then click the propagate Extents tool. To match the setting out of Level 1 to other levels you can use the propagate extents tool. You can control the grid head visibility and get the arrangement how you want it on this plan. The position of the grid heads is controlled by the DWG file. This is a very fast and effective method of creating a grid arrangement in Revit.īelow is the grid in Revit with the background drawing hidden. Once you have established the accuracy of the drawing you can then use the Pick Lines tool to pick the line work representing the grids. ![]() If there is a slight inaccuracy then Revit will report that the Grid is slightly off axis. It is obviously very important to check the accuracy of the imported drawing and also make sure that the rotation and angles of the grids are accurate. Sometimes you will want to import an Architects drawing that shows the setting out of structural grids. Working with a DWG Grid and Propagating Extents You can then set the start number and select Run, the toolkit will then renumber the existing grids. Once the tool is running you use the Pick Objects tool to select the grids you want to renumber in the selected order. The toolkit is found on the Add in tab and you will then see Renumber Elements on the Excitech Tools ribbon. This can be achieved with the Excitech Toolkit, see my previous post for download details: If the grid has not yet been established then it would make more sense to add the new grid and renumber the remaining grids. If you are simply adding a supplementary grid then this poses no problem as shown below, you would just need to edit the witness line on the string of dimensions to incorporate the new grid. Lets first start with the renumbering of grids you can of course do this manually but this can be quite time consuming, especially on large projects. Working with DWG’s and Propagate Extents.A fairly long post but hopefully worth it! To most, the creation and management of grids may seem fairly basic but Revit does have a surprising number of tools to assist with grids and levels. I have had so many questions regarding the visibility and control of grids over the last few weeks that I thought I had better create a blog post and video outlining some best practices when working with Revit grids.
