hi,

i'm using revit 9.1 for a biotech campus (7 acre site) on a countoured site. we've got 5 buildings on one combined podium / basement and i'm having trouble with :

1. exporting to autocad : the cad drawing shows site / topography lines which are actually switched off in visiblity of the exported view.

2. the buildings are modelled as masses, and when i export the roof plan to autocad, they export as wireframe. they lose alot of formatting of linework and need to be almost redrawn in cad. at floor levels where the mass is cut, it behaves ok, but viewing the mass from above, revit suddenly doesnt read it as an opaque mass. i have checked all setting of the mass and view and even contacted my autodesk centre. they told me to create roofs for the geometry to read in the roof plan. but that'll be a hassle. the crazy thing is that when i try to print with vector processing it shows me all this extra stuff i dont wanna see, but when i print with raster processing, it prints correctly. but to get a good quality raster print takes forever. i saw an earlier thread about this [Fri, Aug 19, 2005/ Re : Mass plotting transparent] but it didnt work for me.

4. We have remodelled the contours and by controlling the phasing i am able to show the demolished contour line in section alongwith my new section. however the demolished topo is an opaque mass in section (hidden line view) and it hides all my new construction in areas of 'cut'. i cant make it wireframe to keep the dwg readable and i cannot create exact detail lines matching this contour line coz it doesnt read the topo geometry. ( last resort is to make an apporixmate imitation line.)

5. i wish revit would create sloping pads for basement ramps and treat topography / subregions as solid geometry.

6. I have a HP deskejt 1180 printer which prints a dashes line thru the top/ centre/ bottom of the plot when i print directly from revit... everytime !! no such prob with PDF or cad.

thanx...

1.  Is the topography category actually turned off in the View Properties Model Category Visibility [V V or VW]?  Just 'hiding' in view won't work [susnglasses icon].

2. Adding roofs to the massing is a single mouse click.  Use the 'Roof by Face' command on the Massing Tab.

4.  You need to read up on Phases and Phase Filters to control the visibility of 'demolished' objects.

5.  Sloped pads have been a wishlist item for a long time.  Maybe Revit 10 will help??

6.  More printer memory will probably help.  Check with HP.

hey, thanks for your response.

1. topography is actually off in the view properties.. not just hidden in the view. thats why a raster print is fine.

2.  i did finally add roofs using mass face, its easy to edit and recreate roofs too. but i wanted to figure out why the mass was reading as wireframe when everything else in the view is hidden line.

4. i have worked on the phases.. my problem is showing the demolished farme as wireframe (dotted lines), so that my new phase (which is in hidden line mode) shows through - in the same drawing. i managed to make the demolished phase dotted, but i cant control its opacity separately without affecting the rest of the dwg.

6. i've started printing on the older 1220 c Hp and its printing fine... so its definitely problem with the printer, not revit.

2.  Masses, by default, are a "transparent" material, so they will print wireframe like a piece of glass.  Change the material of the Mass to something solid, and they will print solid.

the masses do not have the default mass material.. i have changed it to a solid white material and made sure transparency is zero... problem persists !
