Hi to you all. I am very new to revit. Had only a couple of days of practice. I came across revit when doing a project for school( studying civil engineering). Seemed to me as an interesting task and much more rewarding to create that project in 3d and then cut it instead of making just drawings and never having a model. I am using revit architecture 2011 with student license. I have gone through tutorials and have learned a lot with the past couple of days but I have a problem/question when it comes to creating wooden framed walls. I am doing a 2 story house project which needs to have wooden frame(50x200mm beams). The cross section would look something like this from exterior to interior. wooden siding,28mm-air gap,35-(wind protection board,20mm)- beams(between which insulation) 200mm- added insulation board, 50mm- gypsum board 13mm. Searching for a solution ive come across that wooden wall extension but that really isnt an obtion since I dont have a subscription. So far I mastered the beam system tool and even created vertical beams via section plane. But creating the core and then just outlining it with thin walls from each side doesnt seem to be a reasonable option. I tried that just for fun and it doesnt let me move the beams after having them layed down with a certain offset and when creating a window it only goes through one wall. This seems like a stupid try, I know. So I am really hoping for some advice of how could I create that kind of a wall. Sorry if I some of the technical terms are very off. English is far from my mother language.

Revit's walls only include layered elements and horizontal sweeps.  I suggest you model the wall as a wall - whatever the thickness is - and ignore the structure in the wall definition (except for thickness).  Then if you need to model the structure, do this separately.

There are many 2D detail components, to help you in modeling the components at detail level. Most of us just show the wooden portion of the wall as a thickness, some will add the sweeps for sill, and double top plate, in western platform framing, California.

Hmm,  Okay. Another question is that if I take sections cuts and need to add some little details in 2d to that section cut., because I might not get it to such level of detail in 3d as I am hoping for, just based on the lack of skill. What is the best way to do that. I suppose one way is to export the section cut from revit to autocad but are there any more options?

Why would you ever want to export to CAD? (I understand...just not good)

You will learn to love detailing in Revit because it is so much easier than CAD,  Vut your section and learn to use several different tools:

1. Add detail components
2. Edit cut profile (This will be something new for you.  It allows you to edit the wal a model element looks when cut in view)
3. Linework tool (Allows you to change line types and even turn model lines invisible)
4. Filled and masking regions
5. and obviously linework.

Sorry. Didnt know if and how to just simply edit cuts in revit. Didnt find the tools/place to just add simple lines and such. Only reason why cad came into mind.

No, no, no. Revit is so far superior to ACAD. when draw a section it pops up immediately, then you can do a call out of a portion of the section. in the callout, you add detail components. these are found in the annotation tab, and work great. all the little components should be there that you need. and you can make more a put them in there. bolts, steel beams, and of course there are regions, to show textures etc. there are also lines as needed. and the wonderful part is that once you create your section, and callout, etc. and place them on sheets, revit tracks and maintains the callout and section bubble tags, so it always shows the correct sheet, and number. Good luck, once you have got the hang of detailing within revit, you won't want to go back.

Nice. Cant wait to get back on the project. One thing I have noticed though is that I am lacking in materials and hatch patterns. In some of the tutorials Ive watched they are using materials which I dont have. And a lot of the materials are missing hatches. So I duplicated a material. Renamed it( in estonian) according to my project and wanted to select the cross section hatch and surface pattern. but I feel as there arent enough. I have both autocad and autocad architecture installed and there are some patterns in there which my revit doesnt have. I know how to load a pattern and I think that it is possible to use autocad patterns in revit but I cant seem to find them. Or maybe those original patterns which come with autocad arent excisting with separate files? For example I didnt have a gravel pattern in revit. I found it by googeling but autocad has it by default. This topic is turning into a lot of questions but I feel like its easier to ask people who know a lot more than me to keep wasting time figuring out such small but vital details. Thanks for all the input guys..

I believe the hatch patterns for ACad work in Revit, and there is the hatch builder as well.

The hatches will work but I am not able to find them from the autodesk folder. I was exploring the schedule feature which blew my mind away with all the features and details it has. It is going to be very handy in energy calculations. However when calculating wall surface area. I want the inner surface area of the walls. Revit by default gives me the areas along the center of the walls. What do I change so it calculates from the inner side of the walls. Tried changing location line to finish side interior. But it didnt make a difference.

I believe the autocad hatches are all together in one file.  In the past, I have copied out different ones to seperate files and loaded those.  Simply search for *.PAT files.

For only the inner surface area, you might try assigning that inside wall layer a unique material, then doing a material takeoff.  << Should work but I have not tried it.  Let us know.
