Hosting Car Parking Spaces to Sloped Ground

[paul.cosgraveJZT74]

I have a carpark - modelled as a floor - which has cross falls on it.

See attached image.

The red lines are showing where the car parking space lines are, 2600mm apart.

The black lines are split lines of the floor, falling towards the green dots, which are gullies. The gullies are positioned to be centred on a car space to prevent somebody stepping out of a car in high heels etc and standing into a gully.

Has anybody any idea how to create parking space lines that will be hosted by the floor I have drawn, and adhere to the slopes? Anything face based I put in snaps to one face or the other and parts of the lines disappear under the road.

Check Work Plane-Based and uncheck Always Vertical in the Family.  Host to sloped Face or Work Plane  in Project

I don't think that works for Parking Stalls--they attach at the front end and then "cantilever" out over the slope.

I remember many years ago before the "Site Tools" came out, Eagle Point (who Adesk purchased from) came into the office to give us a demo.

I asked them to create a quick sloped parking lot. Major fail, in front of our whole group including leadership.😐

[paul.cosgraveJZT74]

This is exactly the issue... the lines cantilever as such, being hosted by one face.  

Attached is a crude sketch showing the issue. Red lines are the surface at falls. The blue line is the parking space lines hosted by a face. It doesn't 'bend' or 'wrap' to the surface of the car park.

I'm trying to think of 'clever' ways to get around this. I was going to model a new floor 10mm thick to the shape of hte lines, but this is enormous work and not an option.

I've 500ish spaces across a large car park at falls and different levels. 

Any suggestions?

So we're talking about a Parking Space that straddles two different hosts/work planes having two different slopes?  Is that right?   

[paul.cosgraveJZT74]

Correct. There is one drainage gully in the road per 4 parking spaces.

The spaces are constructed to a fall, with the central point being in the middle of the four spaces, per attachment to original post.

I've attached a snip from the model if it helps clarify. 

The car park surface is set to transparent at the moment, you can see a main drainage line underneath the road. 

Blue lines are parking spaces. Red arrows show direction of flow. The green square is where a gully will be, which will be piped to the main pipe under the road.

As you can see, some parking spaces have 3 or even 4 planes.

The OOTB Parking Stalls only "host" to a surface at one end.

As a tedious workaround, we have actually used Subregions to indicate parking striping on sloping toposurfaces. "Painted" by assigning subregion a paint material. Lots of copy/pasting, but it works. I think there is a limit on the number of lines that can be contained in a subregion ( something like 999?) so we had to create multiple toposurfaces with the subregion parking striping. We used the subregions for directional arrows, etc. as well. They render nicely and display well in colored site plans.

Thanks Chris, I can see that this would be a good, well, workable solution if I'd modelled it as topo.

I actually have my road modelled as a floor, which I have built up by the layers of construction, stone bases, wear layers etc.

Am I goosed??  I won't be remodelling with top and all the levels again at this stage. 

[cbcarch]

You could model the parking as "subdivided parts" of the Floor? However this adds a lot of complexity--so I'd not recommend it unless it adds a LOT of value to the project.

Are most of your site plans ( and floor plans which might show parking) normally 2D Views?

i.e. could you just use Model Lines or detail lines for the parking stalls and striping? 

We used the Topo/Subregions to show them in high-quality renderings where we really needed to see them. And as a plus, they worked for 2D documentation a well.

Can you model the parking surface as a monolithic construct and shape-edit it using Modify Sub-Elements Tools?  

If so, Railing will follow an undulating host surface.  

[paul.cosgraveJZT74]

Model lines might have to be the answer.
We do export navis files for co-ordination purposes, but usually this is within buildings, steel frames, etc. I might need to create 2D masking regions for the 100mm (4") white line paints. But it would be good to have them in the 3D model also..

[paul.cosgraveJZT74]

Develop a railing style to mimic painted lines?

[barthbradley · Accepted solution]

Sure. That's what I'm showing above. 

...here's a better one. 10'-0" wide yellow stripe done with Railing.  😉

...and following the undulating surface.  

[cbcarch]

Just for fun, here's an old post from 2011 that I started, requesting parking stalls that attached to sloped surfaces.

https://www.revitforum.org/showthread.php/1537-Revit-Architecture-Parking-Stalls-attach-to-slope

[cbcarch]

So, a "Railing Schedule" to quantify the parking stalls? Just the ones parallel to the cars.

Workarounds are just that. But I suppose it could work? I don't like it.😔

[paul.cosgraveJZT74]

This is why I'm here!

Thank you very much. It's a work around I'll happily accept. Created a 100mm wide, 10mm thick railing which is hosted by the undulating surface. 

Looks exactly like what I want. Ideal, thank you.

Does the railing have a thickness?
