Drape Tool for DTM Roads
-
can you post a picture of that enormous terrain when its finished? I am really curious to see what a 75 mb terrain looks like (must be half of Europe...)

Remus,
A man will do strange things when beaten down by Bugplats.......
Plot-Paris,
No,not half of Europe...but sure feels like it.
I'm certain the file ballooned to where it is now simply because the contours are at 2' intervals covering over 250' of elevation change.
Guess my thinking was similar to having a large image file, you can always reduce the amount later.Best

charlie,
my problems with draping roads onto terrains only ended when i discovered that the best way to do it is to pushpull the road through the terrain, select both and intersect-selected them. then you just erase all that is not needed and you have your road surface.

I apologize in advance for offering something that probably won't work with your sophisticated model.
However is there an option for draping using the Google Earth with a 2d map of your model, then importing that terrain into SU to work with?
Attached is a topo map(could be any 2d digital model) draped onto GE(plus). The roads, trails and markers were added separately into GE. This could be imported into SU for further modelling enhancements.
With a simple small rough scale model it works well.
Good Luck

Charlie,
I would like to know if you have figured out how to cut the save times down. I am working on a similiar topo, (site, house, driveway huge vertical drop, ), and it is running about 50 megs with a skin, I have cut the topo down to a component that is 1/5 the size by cardboarding the topo and instead of 1-ft contours I am working at the 5' internals. when I finsih I will replace the component with the one ft contour version.I would like to be able to capture the file and send it to another drive to perform a save, so I can keep working, this would also be nice for some SU to Cad exports, I have exports that take a-long-______time, somewhere close to 24 hrs. Has anyone done anything like this?
Saves on this topo run about 2 hours, all i can do is work on another machine while this is going as any other activity (cpu usage) delays the outcome drastically. The 5' contour model takes about 20 min to save. machine specs are similar to yours. needless to say, I think twice before I save, My autosave increments are 99 min.

Edson,
Thank you for this, I actually modified the hangar pad for phase one this way.
So intersecting is far more reliable than Drape.......hmmmBest

alpmeadowalpmeadow,
No apology necessary, in fact I may have to consider something just like this as I am still cooking the Drape....now 54hrs.......
Thanks for this,great group here

[quote="rhankc"]Charlie,
I would like to know if you have figured out how to cut the save times down.Hank,
To be completely accurate the model[dtm only] was around 82mb after the from contours finished.
I then deleted the imported contour lines, then pasted the roads/lots/trails and the resulting file was 75 mb or so. At that point Save time was around 5-6 mins.
I too have upped the auto save interval, but 2hrs to save?
Your Save time seems really excessive, have you purged unused?
Closed & Re-opened SU. [heard this seems to speed things up on large models]As mentioned above I am in Hour 54,and still hoping the Drape completes.
It's now kinda like pulling a life support plug......when is the right time to say enough.Best,
C
FYI...I will post how all turns out....no matter the news. -

I deleted mine too. One thing I havent figured out, the skin version was formed with a very small triangulaed mesh, I deleted that too, and when the skin, its' border and the drape lines were the only items in the file the drape took about 30 min. Did you delete the fine triangulation after the skin was formed? along with the contour lines. I think the biggest problem is: I didn't clean up the topo sufficiently, and there are ghosts messing with SU.
One thing i am realizing, the more entities are native to SU, the better these monster "real quick" studies perform. Lots of imported cad stuff+ Slow SU. You have to delete all the cad structure (layers, line types etc) and reorganize all of it the SU way.

Hank,
Nope, did not delete the fine triangulation...........awwwwwwww....sh%*As for the more homegrown SU the better things are....that may be the quote/understatement of the year!
Thanks again,

Hi guys,
Working with such large models consumes a lot of RAM because SU needs to keep all previous geometry in memory despite you delete them just to be able to perform the Undo command.
Have a look at Coen's tutorial here how to overcome this (and also it is a good technique for other issues as well).
-
Gai,
Great Tutorial. Timely too, I was just manipulating a lump of components to affect some layer manipulation. Good trick, thanks for showing it to us.
Best Regards -
Hank, after all "SketchUcation" is an "educational" site!
Just wait until those pages will boost with lots of tutorials! -
Update:
Let the Drape cook for around 96hrs.[was not home when it completed].I still have info to add to this model so I will definately try all the alternate/congruent suggestions provided thus far.
Thank you all,
Best

FYI Current Model is 90.8MB
-
wow, 96 hours is a long time
I cant help but wonder what the hell SU was doing all that time... -
Remus,
You and me both..........Glad I Did NOT pull the plug!

Anyway, impressive for sure. Now comes the modeling (and stamping) part!
