Random Terrain cotutors, no supporting elevation data

I imported a Import a surveyor DWG file. I followed the instruction in the tutorial (Import a Surveyor DWG file for a Site Plan or Terrain Perimeter (chiefarchitect.com) . And got some strange spikes hills. I have tired cleaning up the elevation data but no luck. There is simply no elevation data in the area that is that tall, not sure what is generate this. Pleas see the attached pic and surveyor map.

If this looks any better give these setting a try or go to medium if you have a faster computer than I do.

 

Linear was giving you the issues.  Also there is way more elevation data than chief likes to handle and I would guess your surveyor did not actually take over 5000 measurements unless he used a scanner which from the PDF it appears he did not.

 

I would try working with less of the data as it would appear that most of the data is computer generated and not measured.

 

Chief would likely come up with something close to what your surveyors program did with using the measured data.

 

Not enough time to actually look at the .dwg right now but check and see if the elevation points are there.

If this was the biggest anomaly you got from chief in terrain then that is amazing... its usually a crap shoot as Chief is pretty difficult to get terrains down to a t. I've had some work without a hitch then others look like a porcupine. I don't fully understand all of the adjustments but I've had fairly good luck with low terrain surface smoothing and higher  terrain surface triangle counts. I have yet to get retaining walls and such to work as desired

I run into the same problem as the others importing terrain data. It drives me CRAZY and I have not found a good solution.  When you live in the Ozarks like Lakeside-E and myself this simply doesn't work.

 

My local cities require the detail elevations / contours and many many of my projects are on acreage with hills and slopes everywhere.  PLEASE, give us some better options with contours and elevations.  The best solution would be to contour the imported data as is and use this as the contours.  If this isn't possible give us a better polyline simplification that merges the point further than the current options. Or ways to control linear after the first creation with editing the contours directly.

 

When in the hills of the Ozarks the land is never flat.  There are always lakes, rivers, ponds, hills and valleys on a single lot. And the lots are often over acres.  I had to provide 2 plans this year over 500 acres. (this is unusual)  Drainage has to be shown on surrounding lots.  It is such a pain.

So when you hire a surveyor to do a terrain plan for 500 acres, how many elevation points does he record ?

For what it is worth, I gave up even trying to import survey data to "automatically" create terrain planes for the exact same reason you are now complaining of, and commonly such resultant constructs are too complex for the common PC or Mac to easily handle in 3D.

 

What I now do is to import the graphical data and then MANUALLY  convert selected lines to "Elevation Objects" or tracing over such imported lines with custom terrain objects. This is, of course, slower but it keeps ME in control of the process (and not pre-programming) and I like that a lot better AND I then, with certainty always get a useful product.

      Hi all, Just wondering if anyone could help with some issues Im having with importing 3d symbols - I am trying to import some SKP files into chief (decor, people etc) and while some are coming in fine others are coming in with no texture/materials or the materials are not applied correctly (eg a symbol of a person the texture is placed wrong) - if someone could help me out with how to "lock" the material that would be super helpful. Thanks 
       
      first image is how it appears in sketchup and second how it imports into CA

      I ran into some weird problems a week ago, and with help from experts here, I figured out my problem: Importing DWG elevation data is hit or miss--if it wasn't set up for a logical terrain perimeter, or some elements of the terrain elevation layer are 0, it will totally mess up the Terrain Build in Chief.
       
      Import survey data to a neutral layer (that is, don't map to elevation data), or just import a PDF file for tracing. Experts warn against using elevation points, and the tutorial videos make elevation lines seem like the obvious choice for creating fairly simple slopes. In my case, I modeled an entire neighborhood by tracing ~40 contour lines. Chief warned that building terrain with 2000+ interpolation points in non-Linear mode might take too long, but it finished in a few minutes.
       
      Avoid these pitfalls:
       
      Make sure the elevation splines start and end outside the Terrain Perimeter Don't let contour lines cross (thanks, @glennw!) Make sure that each elevation spline is continuous--I kept missing by a few pixels when I zoomed in, meaning that most of the spline was at the elevation I set and part of it was at 0. Move the ends near each other and Chief makes it just one spline. Double-check each spline's elevation--if just one is 0, your terrain will be messed up. Good news, though--fix it, re-build, and you're good  
      My smaller tests were successful, so I went for the whole 11-acre neighborhood--27 lots. My Terrain Perimeter is 892' x 550'.
       
      Note: I didn't have to trace anywhere near the number of contour lines you see. I traced a plan with a 5' interval, and Chief interpolated to a 2' interval. Actually, I skipped some contours that added no value, but of course, Chief didn't.
       
      Thanks to @glennw, @Renerabbitt, @Kbird1, @Chopsaw and--from a 15-month-old post-- @DavidJPotter

      Clearly, I'm not thinking about this correctly.
      On a new plan, create a default terrain perimeter. I drew 8 elevation splines, careful to start and end them outside the terrain perimeter. I opened each spline in turn and set the elevation to 92', 94', 96'...up to 106' in the upper right. Zooming in, the splines are labeled, showing that the lines are around 100'. Each spline started at the default elevation 0', but I manually set other values. There are no other objects on the plan that could suggest anything but 92' to 106'. I checked--Terrain Perimeters don't have an elevation.   
       
      So, imagine my surprise when I built the terrain and got this:
          
      This can only be caused by my utter misunderstanding of how elevation splines are meant to translate to contour lines. Help!

      Good afternoon Chief users,
       
      All of our projects to date have been pretty straightforward terrain-wise, and despite spending way more time on this than I can to admit, and watching all of the tutorials I am still scratching my head. 
       
      A little background:
      The site for this home has a lot terrain character, swales, hills, etc. Due to this, we brought our survey crew out to GPS map the site. I followed the Chief tutorial to bring in the terrain data generated (very slick process). During the design of this home a goal was to minimize grading and to preserve the unique characteristics of the site. I decided to stick the uphill side of the home into the hillside with a taller retaining stem wall to "split" the grade over the width of the home. 
       
      Struggles:
      To get the site grading to mimic what we envisioned, I used elevation areas, some with "interior is flat" checked, a lot of trial and error during this process. One terrain modification I did was creating a flat area around the front of the home for the entry, and parking. Coming off this elevation area is where I am struggling. I have tried using multiple elevation regions and elevations lines to force the terrain to build at a gentle slope off of this pad. From my calcs we could easily adjust the driveway grade to have an appropriate slope. The problem area (directly off the flat parking area) is about 12 feet of rise over 80 feet of run (15% slope). I just want this area to be filled to allow for an even 15% slope. I have bumped up line weights, colored them red, and removed unnecessary information from the screenshot attached below for clarity. 
       
      Do any of you terrain wizards have any advice for me? I am happy to attach the plan file if desired. 
       
      Thank you all,
      Austin

      I'm trying to replicate a window sill I have on a model in SketchUp. I can import a .SKP file and convert it to a 3D symbol just fine, but then in elevation views, CA wants to show these CAD lines every couple inches for some reason. The 3D view looks just fine, but I do need to be able to create elevation views as well. Is there some checkbox I could toggle and solve this issue?
