Parking on Topography

[Anonymous]

Hello.

I'm using Revit Light 2018 for PC, and I've got a topography site that I have created from a .dwg file, and i've split the surface to identify the roads. 

How can I 'paint' the parking bay components onto this existing surface (which isn't level)? Or do I have to create a building pad or floor to receive the bays? I don't want to do this as it won't reflect the site conditions, but that is all I can see from my scanning forums and knowledge files. Apologies if I have overlooked something previously posted. 

For reference, I have downloaded the parking bay components into the file, I've placed them on the topography and they either hide below the ground plane, or seem to float above it casting shadows - I've checked if I have offset them, and I'm re-hosting them to the required surface, but nothing appears to work.

Many thanks.

Use sub-regions for different areas and you can give them different materials.  For roads, between splitting the topo and sub-regions, I would choose to use sub-regions as well.

In case you want to turn the topo parking lot to actual structure:

What do you mean by "paint" the parking bay components?  What components?  Are they modeled components?  How are they hosted? If they host to a Level, then you need to either lower the Toposurface to the Level that you are placing the component on, or place a Level at the proper elevation and put the components on that Level.  For instance, say the the components are to be placed at the Toposurface's 100 ft. contour --  you would lower the Toposurface 100 ft in a an Elevation View, or you would raise a Level 100 ft., or place a new Level at 100 ft.

...I think I may have misunderstood you. I believe you are talking about Site components. These are the components that will host to Toposurfaces.   If they are indeed Site components and you cannot see them, I suspect they are not hosted properly.  You can use the Pick New Host tool on the contextual tab to host them to the Surface.  If they are not Site Components, then what I said before is accurate.

They only works with flat surface (level based families) and/or one direction sloped surfaces (face or work plane based families).  For complex surfaces from a topo, you may need to create them using Railing tool because Railing can follow the topo slopes.

Create a railing type with only Top rail component. Create a thin profile and assign it to the Top rail type and give it the striping material.  Duplicate the Top rail type if you need different striping sizes and/or colors.

Many thanks - I did try this, but they remain floating. I presume this is because the topo-surface is not level and therefore the car parking site component can't relate to that (apologies if my technical language isn't quite correct...)

Many thanks.

I have used sub-regions for the road itself, but I need the car parking spaces delineated as part of the same surface (or sitting on top of). The link looks very useful and will be bookmarked.

Marvellous, many thanks.

This is just what I need - particularly when I realise that the pick new host button is very useful. Now I just need to figure out how to remove my teeny balustrade posts from the railings. 🙂

Edit railing type and set all balusters and posts to None. You only need a top rail.

Thank you again. 

Sometimes it takes me a little bit of searching, but I get there in the end.

This is good for parking spaces, but what am i doing when i want to place other components like bushes, bench, table, car, garbage can, etc.

Yes; your right!  

P.S. What are we talking about?  I just got pinged on this year-old thread. Is this the one about the baby on a bus?

no, its for how to place components on topography and it should followe the
topography slope when the topography is not leveld

Okay then…🤔...so what are you asking about?

You want a tilted bench so seaters keep sliding to one side? Or a tilted trashcan that keeps falling off?

[Anonymous]

i want it should be laying on the floor, i don't want it should be one side
on the floor and on the other side it should be like flying or being
inside the floor

[ToanDN]

How would you do in real life? You either create a flat surface like a pad to place them, or make the legs longers and burry ine side deeper than the other. Do the same in Revit.

right but some times you just want to put your chair out side on the hill
and sit like this, or you want bushes on the hill and you want it shoud
follow the slope

[ToanDN]

Set those family to always vertical and place them away. They will be upright on the hill or not.
