Sawyer Posted March 17, 2006 Share Posted March 17, 2006 I am trying Revit again & I have forgotten everything I knew. Anyway I have a set of as builts & the dims I am working from are not to center of walls but to the edges. How do I draft walls from outside faces instead of centers. Does that make sense? Also I need a set of as builts, demo and new I see the demo icon but how do I draw new walls that only show on certain sheets not on the Demo or as builts?

Crazy Homeless Guy Posted March 17, 2006 Share Posted March 17, 2006 i am going through Revit training, but we havn't had a class since last week, and i right now i am going from memory. ...i think you select the wall tool, and then on the option bar, or whatever it is called, directly above the working window, where the option are for the tool. i think their is a pulldown or something there. i think it is called loc line, set that to outside of wall.

Sawyer Posted March 17, 2006 Author Share Posted March 17, 2006 Thanks Travis. I am going to have to uninstall autocad if I am going to learn Revit. I am so fast with plain old cad if I have problems with Revit I just do it in cad. Link to comment Share on other sites More sharing options...
Sawyer Posted March 22, 2006 Author Share Posted March 22, 2006 Ok I am getting back into it and I like the simplicity. Now everything looks great in Revit. In max it looks like pants. The upper image is the Revit view with 2 different sized arches in 2 different walls. The bottom view is the same walls isolated and you can see the tops of the walls are not cut right. They are not round or smooth. Ideas? Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted March 23, 2006 Share Posted March 23, 2006 i don't think i can help you on that one. at least not yet. we have only completed a 3 day beginners class. we go to the intermediate classes on April 1. that is where we learn how to make our own objects, and i presume that is where i might learn the answer to that question. you might want to see if richard mcarthy is around. i think he is a revit user. __________ edit, of course richard is a revit user, he is the mod of this forum.

Richard McCarthy Posted March 23, 2006 Share Posted March 23, 2006 Hmm sawyer, what version of Revit are you using? And also, that wall not cutting right, was that view in REVIT or in MAX? cos Revit has some problem with mesh exporting out to MAX, for example the wall joints, but I never seen problem with wall cut like that.... It is VERY peculiar... Are you sure you cut it from the correct view? Create wall -> edit profile -> Draw the desire line, TRIM the lines so it becomes a solid shape, click done. Export to DWG, you get 2 options, either save as ACIS solid or not. What I found is that, with ACIS solid, you get less mesh divisions (less polygons), while without, you get a smoother look on your arc. Import into MAX (uncheck "Weld", "Unify Normals" ) and this is what I get... Tested in Revit 8.0 (we havn't upgrade to 8.1 yet), 3DS MAX 7.5. Image 1 : With ACIS option turn OFF during export Image 2: With ACIS option turn ON during export. Link to comment Share on other sites More sharing options...

Richard McCarthy Posted March 23, 2006 Share Posted March 23, 2006 Just did a quick render with it, doesn't seem to have any problem with wall joints at all like your pics displayed... 3DS MAX 7.5, Daylight system, Advanced Light Tracer Turn ON -> (30 seconds job ) Link to comment Share on other sites More sharing options...
Sawyer Posted March 23, 2006 Author Share Posted March 23, 2006 Thanks a lot Richard. I am using Revit 8. I tried switching the ACIS solid option and no difference. I created the wall in level 1 view and from component I modified opeing eliptical arch and placed it into the wall. It looks great in Revit but in Max (8) I get a horribly cut opening. Now I just redid this as a .dxf and if I have it as a polyface mesh not ACIS the arch is fine. But this leaves me with disconected faces. Link to comment Share on other sites More sharing options...
Richard McCarthy Posted March 24, 2006 Share Posted March 24, 2006 I think maybe it's some curve that Revit doesn't understand. Why don't you just recreate that wall ? it's very easy using my steps: Create wall -> edit profile -> Draw the desire line, TRIM the lines so it becomes a solid shape, click done. Export to DWG, you get 2 options, either save as ACIS solid or not. What I found is that, with ACIS solid, you get less mesh divisions (less polygons), while without, you get a smoother look on your arc. Import into MAX (uncheck "Weld", "Unify Normals" ) and this is what I get... Tested in Revit 8.0 (we havn't upgrade to 8.1 yet), 3DS MAX 7.5. While you are editing profile of the wall, you can import a sketch of the component wall and trace the outline around it using the line tool ofcourse.

Sawyer Posted March 24, 2006 Author Share Posted March 24, 2006 Richard -thanks for the help I will look into that when I hop back to that project. I have anther question for you. I asked the Revit people this in a class last year and no one knew how to do it. Basically the level of detail I find for all BIM files is not good for rendering. One project I had which was supposed to be drafted in Revit (not by me) and I would just get the updated file and render had these really soft plaster corners. Basically no one could figure out how to do this and I did everything in max. I may have another project from these guys and I want to see if anyone knows how to do this in Revit. Not just a fillet on an ext corner but the smooth bullnoses around the windows/doors. Anyway thanks Link to comment Share on other sites More sharing options...
Richard McCarthy Posted March 24, 2006 Share Posted March 24, 2006 This looks more complicated, you have to create special family for it. Those corners, and bullnoses and round shapes, I think Revit wall tool simply can't create them. So, you have to go the family way and create special components for it. Even with family creation, I think u will find it hard to do those freeform shape accurately as there will need to have some "compromises". (eg. using multiple shapes and void shapes combined to form one of the shapes of the wall) It's one reason I advocated/suggested to Autodesk that Revit needs to have a more freeform/sub-divisional modeler built-in like ala' "SILO" style that let you "box model" then sub-div. No plans for Revit to get that kind of capability yet so you have to make do with compromises in Family editor I am afraid. Also, I MIGHT BE WRONG... czoog probably knows a way around it, so what do you think czoog ?..can u model that accurately without compromises?

Arnel Posted March 25, 2006 Share Posted March 25, 2006 I think that can be done using wall hosted void family component then just align with your window opening. Link to comment Share on other sites More sharing options...
