1、Revit QARevit Q&A: Q1. Can you save a file created in Revit Architecture 2010 to an earlier version and open it in that earlier version? A1. No! Revit has no means of saving its project file from any release back to early releases. So Revit Architecture 2010 cannot be saved back or opened by Revit A

2、rchitecture 2009, or earlier. There is simply no backward compatibility. This is because as Revit building elements and components are enhanced with new features and new commands that allow improvements in Revit elements and components linking and constraint relationships there is no way to support

3、it in a prior release that did not support the same parametric relationships. That is why it is critical for Revit users to be on subscription and maintain the latest release or make sure that any work they do and any consultants involved using Revit MEP or Revit Structure must be using the same rel

4、ease. Q2. How do you export a Revit drawing to AutoCAD? A2. In Revit, select from pull-down menu File, Export, CAD Formats, browse to folder you want to save it to. The default CAD type is an AutoCAD 2007 DWG file, although you can also save to 2004 or 2000 versions of AutoCAD, to a DXF file, to a D

5、GN (Bently Systems Microstation format), or ACIS SAT format (this is a 3D object-oriented software modeling kernal developed by Alan Grayer, Charles Lang and Ian Braid as part of Three-Space Ltd., and sold by them to current owner, Spatial Corporation); SAT is an acronym for Standard ACIS Text. You

6、can rename the file name as you save it. If you have one of the plans, sections or elevations selected at time of export, the plan (complete with all tags and callouts) will be converted to a 2D drawing in AutoCAD. If you have a 3D view selected, the AutoCAD drawing will also be 3D and Revit entitie

7、s wil be converted to polyline meshes in AutoCAD. These can be exploded several times down to lines, arcs and circles, but will lose their 3D appearance. The most useful way of bringing your Revit drawings into AutoCAD is to bring in the plans and elevations separately. Q3. How do you import an Auto

8、CAD plan or elevation drawing into Revit? A3. In Revit, select from pull-down menu File, Import/Link, CAD Formats, then browse to and select the drawing you want to import. Before you import the drawing, in AutoCAD do the following: 1. If you are using Architectural Desktop or AutoCAD Architecture 2

9、009, set the variable proxygraphics to 1 (it is 0 by default). To do this, simply type proxygraphics at the Command: line and then 1. This will allow walls, doors and windows in plan to be imported. 2. I recommend freezing notes and dimensions. These do not translate well into Revit and it is easier

10、 to redo them in Revit itself. 3. The drawing comes in as a 2D drawing even if it is 3D to begin with, so you will need to retrace walls and insert doors and windows into the Revit drawing after importing. The drawing comes in as a block in Revit, so if you want to move anything around in Revit you

11、have to explode it. To do this, select the plan and then select the Partial Explode button in the Options bar. The full explode option is not necessary unless you want all the AutoCAD blocks and Xrefs to be exploded as well. It is a mess. I recommend that you only use the imported drawing as a guide

12、 to trace over into Revit. Q4. How can you bring AutoCAD details into a Revit drawing? A4. From the View Design Bar, select Drafting View. The New Drafting View dialog box will appear. Set the scale for the view. This will create a blank page onto which you may import any AutoCad detail you have. To

13、 import an AutoCAD drawing, select File pull-down menu, Import/Link, and then CAD Formats. You can import any DWG, DXF, DGN (Microstation), ACIS SAT, or SKP (Sketchup) files. Navigate to where the file is stored and select it. You can put as many drawings on the Drafting View as you want, however, e

14、ach Drafting View will only get one label on the sheet you place it on. To get the detail onto a sheet, open a sheet and drag the drafting view onto it. Each Drafting View is given a detail number automatically by Revit. Click on this link to watch a video that shows how to do this: Q5. How do you c

15、reate a drawing index? A5. To create a drawing list: 1. Click View (pulldown) menu New Drawing List. 2. Select the Fields to appear in the drawing list. Some typical fields include Sheet Number, Sheet Name, Checked By, Drawn By, and Sheet Issue Date. 3. To create user-defined fields, click Add Param

16、eter. 4. Specify the Fields, Filter, Sorting/Grouping, Formatting, and Appearance options within each tab. 5. Click OK. 6. Drag the drawing List onto a sheet. Q6. How do you hide and unhide objects in Revit? A6. There are three methods:Method No. 1: To hide an object temporarily (until you print or

17、close the drawing) left click the object to select it and select the “Temporary Hide/Isolate” icon in the View Control Bar at the bottom of the screen (the one that looks like sun glasses), then select “Hide Element.” To unhide an object that has been temporarily hidden: Select the “Temporary Hide/I

18、solate” icon in the view control bar at the bottom of the screen, then select “Reset Temporary Hide/Isolate.” Note that this will work as long as the temporary Hide/Isolate has not been made permanent (that is, there is a blue line around the view and the “Temporary Hide/Isolate” icon is blue). If i

19、t is not, then you will have to use the method in step one above. Method No. 2: To hide an object permanently (until you unhide it) in one view only click on the object to be hidden - it will turn it red. If you want to hide all objects of the same type, such as all of the same design of walls or do

20、ors or windows), right click and select Select All Instances. Right click again and select Hide in View Elements. Or you may also select Category instead of Elements if you mean to hide all walls, doors, or windows, for example.To unhide an object that has been permanently hidden click on the “Revea

21、l Hidden Elements” light bulb in the View Control Bar at the bottom of the screen; change the “Model Graphics Style” in the view control bar at the bottom of the screen to “Wireframe” (because another element might be covering and hiding the hidden element); any and all hidden elements will appear a

22、s colored lines; right click the element to be “unhidden;” select “Unhide in view” and “”Elements;” turn the light bulb in the view control bar off by clicking on it. Method No. 3: To hide all objects of the same type (such as walls, doors or beams) permanently (until you unhide them) use the “Visib

23、ility/Graphics override” (type VV or VG) and uncheck the Walls or Doors or “Framing” box. Note that when you use this method to hide elements, you cannot use the “Reveal Hidden Elements” light bulb in the view control bar at the bottom of the screen to turn them back on. You will have to go back to

24、VV and check the box to turn the category of elements on. Note that all hiding and unhiding of all sorts are view-specific. Q7. How can you make beams and bar joists be visible in Reflected Ceiling Plan? A7. For some unknown reason, the programmers of Revit decided to hide beams and bar joists in Re

25、flected Ceiling Plans, even if there is no ceiling. To make steel beams and bar joists visible in a Reflected Ceiling Plan, go to the Reflected Ceiling Plan in which the beams and bar joists should appear. For very high ceilings you will need to change the view range to the level above. To do this,

26、in the Reflected Ceiling Plan, right-click in the drawing area, select View Properties (or type VP) select the Edit button to the right of View Range. Make sure that the Primary Range is set to the Level Above, and that the View Depth is set to the Level Above. Click OK, then OK. Now click on the “R

27、eveal Hidden Elements” light bulb in the view control bar at the bottom of the screen. The beams and bar joists will appear as magenta colored lines. Hover the mouse cursor above one of the joists, right click and select “Unhide in View” then “Category.” To show the actual width of the beam or bar j

28、oist, change the “Detail Level:” in the view control bar at the bottom of the screen to “Fine.” Note that all hiding and unhiding is view-specific. Q8. How can you make structural elements (beams and bar joists) visible in a floor or roof plan view? A9. Bring up the floor or roof plan view in which

29、you want to make the structural framing visible. Right-click in the drawing area, select View Properties (or type VP). Under the Graphics section, the Discipline normally listed is Architecture. Select the drop-down box to the right of the word Architectural and select Structural. All framing will b

30、e shown dashed in the structural discipline. Q9. How can you borrow a Titleblock sheet to use in a new drawing from another drawing you have? A9. Open the drawing with the Titleblock. In the browser, go to Families, Annotation Symbols, Triton_D_sized_titleblock, then click on the Triton_D_sized_tttl

31、eblock. Right click and select Copy to Clipboard. Open a new drawing. Type V (this means paste from clipboard and is the same as if you selected from the Edit pull-down menu, then Paste from Clipboard). Now you will have that titleblock available to use in the new drawing. Q10. How can you apply a g

32、ravel hatch pattern to areas of gravel (such as subfill material under a slab on grade), if Revit does not have it? A10. You can import AutoCAD hatch patterns. Select the Settings pull-down menu, then Fill Patterns then New. This will bring up the New Pattern dialogue box. Select the Custom radio button. Under Name, type in Gravel. Under the custom area, select the Import button. This will allow you to open the AutoCAD hatch pattern file. To fin
