carpark spaces on a varying level mesh?

[Anonymous]

a problem i often come up against is placing the white car parking space markings onto models with a car park, because every model i do has changing levels in the car park mesh.

i have tried the parking spaces object from the library but it is only any good for flat car parks. i did tweak the scripting on it a bit to allow me to put the spaces at an angle but it made things even more complex!

so i normally end up having to put each stripe of each space in as a wall and it takes for ever.

can anyone think of a quicker easier way using the gravity

It sounds like you are at least somewhat familiar with GDL. If you don't mind placing them individually the script for a single stripe is almost trivial. For a really basic one:

2D:

Poly2_ 5, 3,
    0, 0, 1,
    A, 0, 1,
    A, B, 1,
    0, B, 1,
    0, 0, -1

3D:

Prism_ 5, 0.001,
    0, 0, 15,
    A, 0, 15,
    A, B, 15,
    0, B, 15,
    0, 0, -1

This can then be dropped with gravity onto the site. Revisions to the grading will require replacing or moving them. If the stripes have to slope it's a little more complex, but I'll leave that up to you.

BTW: There's a new object in the AC11 Library -- Parking Stall 11 -- that has a "Terrain Slope" setting , either "Sidewise" or "Lengthwise".

in the UK A11 the parking stalls doesnt have that setting, any chance you could save it out as an object, zip and upload it for me?

How about "painting" the stalls onto the mesh using a custom material with an image file as the texture. Karl is a master at this, or you might so a search.

In the past, I've made a duplicate mesh and subrtacted everything that was not the lines and then elevate the new mesh a half an inch or so above the original. This way the parking lines fit the contour of the parking lot mesh exactly. Hint: click on the edge of the mesh you want to modify (while selected) and select the pet palette icon with the minus sign. Draw what will become the void to avoid modifying the mesh's elevations. I have also drawn the "void" between the lines by drawing the interior side of the parking space with the line tool and multiplying it. You can quickly create your parking lot void as a closed polygon (you don't have to unify all the elements as long as they close) Now you can magic wand a hole in the duplicate mesh. You must cut a hole in the mesh to avoid loosing/modifying elevation points!

If you you want spot on rendering and can forgo the auto numbering and such that some of the library parts do, I recommend the following:

1. Make the stripes (also works for curbs etc.) with walls.

2. Use SEO to intersect them with the parking lot mesh.

3. Use SEO again to subtract them from the mesh.

I did a quick example below..
