View Full Version : How would you model this?

I'm building an airport, and part of it is roads - on two levels - and then they fuse.

I have no problems making the buildings, but the roads make me crazy. Ideas?

I'm using LWCAD if it makes it any easier.

I don't get it, what's the problem ?

1. Do it with LWCAD line/arc tools and then convert to polys

2. or start form straight road part and use Extender to extend edges one by one until you construct desired shape :).

3. put TOP blueprint in view and draw it with Pen tool and then just extrude in height to make thickens.

4. Make spline in shape of road and use Rail extrude with single road part

5. Stencil spline into plane object and then delete rest of polys...

6.....

I'm sure there is at least dozen more ways to do it in LWM :).

Tanks, Lewis.

The shape isn't the problem - getting the smooth elevation however. Here's a link to Bing (http://www.bing.com/maps/?v=2&cp=mjnrrs1v5rvc&lvl=20.014449361522463&dir=88.18853333225317&sty=o&sp=Point.mjngvj1v5pvj_Honolulu%20International%20T erminal____~Point.mjns631v5rjh_Honolulu%20intl____&where1=Honolulu%2C%20HI&q=honolulu).

First take out a peice of paper and work out the relative heights of the various flat areas. But Lewis is right, it looks like you're lucky with this one, the inclined surfaces are straight, and the site looks flat.

Make a SIMPLE model first from several square planes, no curves, to solve the heights and work out that the angles make sense .. then think about your beautiful fillets and bevels :)

Thanks guys. Archijam, that's an interesting approach. I'll dig into it when I get back to it.

I sat a few hours at work today. I got somewhere, not perfect though. Will try again, and again and.. until I nail this sucker.

Funny thing, I've always wondered how you guys model that stuff. I've always been playing with "the simple stuff" like very simple buildings, but roads like this, and with elevation however, makes my head spin.

You can model Road FLAT on 0 Y axis and then "move" it with Linear falloff, just be sire to slice up in few segments so that you can use falloff smoothly.

Yep, exactly how I would do it! This is where Lightwave excels...

YOU BLOODY WHAT?!?!

Ha, never seen that tool before, or touched it... I should pay more attention, but that is remarkable... good times!!

Thanks very mucho!

Well, it's interesting, but what animation tasks does this help?

--Also, "Texture Point" allows you to apply textures to Morph Maps: I have a hard time imagining what activity that would be useful for. (BUT, I know I'm not good with that type of imagination.)

a rough idea would require a few layers and some time but build your road,take it to layout add clothfx to and drop it on some items that resemble you road.after you get your road at the pitch you want save the obeject from a frame.

in the free training videos on the webite look up making a mic. great walk thru.
allowed me to lay a comforter on a bed with excellent corners.
the break you see is because i didnt tie the polys together and it fell throu.
first i built the road i saw on top layer.
Next i built two polys under with a slope.
i then sent to layout and dropped it with clothfx
from there i would find the frame i want save it and load to modler and build the next section that took me 10 mins max to knock out i didnt do a bunch of detail as you would follow up with. hope this helps.(adding more polys will smooth out turns and such.
