Terrain/Contour and Driveway issues on sloping site.


Recommended Posts

Hi There,

I am a current chief architect user and have a question in regards to the contour tool and driveway tool.

I have a plan that has a sloping site that I am trying to accurately portray in 3d for both client and the Local Council.
From the road front the site slopes left to right and from the back to front.
(I have attached Images shown what I currently have)

My question is there something that I am missing I have also tried in elevation converting/extracting a polyline solid but it doesn't quite work.

I have attached a link to the 3d viewer but can add a plan if need be.

Most of the issues you are seeing are typically caused by terrain data that is overlapping or too close causing a conflict for chief's method of terrain generation.  Usually it can handle real world data that is properly recorded and inputted.  Also the flatten pad setting can cause issues with data that is too close to the building.

 

That being said you likely need to post the plan file for someone to be able to help unless you think you have patience to carefully make small adjustments and observe the results if you are making an improvement or making things worse.

Might want to upload the plan while CA is closed and any pics of the Property you have , as we can't tell anything from the 3D though the terrain looks high judging by Doors and or not sloped correctly.  ( not that I am a Terrain Expert :) )

Chopsaw answered your question plus make sure "Flatten Pad" is left unchecked in the Terrain Specification Dialog.

Why do you recommend that David?  flatten pad is very commonly the exactly right thing to do.  The biggest things to understand with terrains are these...

 

1.  Use the proper tools.  Define your terrain with the elevation data tools (points, lines, splines, regions, and terrain breaks).  Only use the modifier tools after the underlying terrain has been properly defined. 

2.  Give Chief enough information to work with (it needs at least 2 pieces of elevation data and perhaps much more depending on the desired contours).

3.  Avoid giving Chief too much information.  It just starts to get confusing, difficult to keep track of, and slows down the terrain generation.

4.  And most importantly (and as was already stated above), don't give Chief conflicting data.  Do not overlap elevation lines, don't leave any lines or points inside an elevation region, and don't place conflicting data right next to each other--give it a little space.

      This is my first time trying to bring in data collected from GPS into chief arch. I have converted the CSV file into a txt doc but when i bring it into chief arch the land/terrain looks very off; there are tons of spikes/triangles on the area and I'm unsure how to make it "smooth". Also unlike other programs I've used when I click a point I don't get a description of the point, meaning i cant tell if I'm looking at a shot of the sidewalk or a portion of the driveway, im wondering if there is a more effective way to input this data or a way that will allow me to keep my codes/point descriptions that I set when i was in the field.
       
      Any info/solutions on this topic would be appreciated.

      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.

      Fellow More-experienced CA users,
       
      I have drawn as-built plans of a house for a renovation/addition project in CA v.12.  I recently received the final survey from the surveyor with property lines, major and minor contours, the building footprint, and other typical survey information.  I imported it from .dwg as a .plan file  with layers for terrain perimeter and terrain, and converted the terrain using the convert tool to make it 3D.  It shows up with terrain. Yay!  Now I'm not sure of the next steps:
      1. How do I bring the terrain into the building.plan?
      2. How do I set it in place - using a Place Point or Point Marker at a corner of the house?
      3. The survey elevations are in the 650' range so how what do I do to place the terrain relative to my house (1st floor 0.0)?  This house has a walk out basement, if that matters.
      4. I copied in a 2D version of the survey to use in plan view (on layer CAD, AS-BUILT SURVEY).  When I send it to layout, the house floor plans are obscured and the secondary contours didn't come in - admittedly, this is a previous version of my survey attempt and I've since remapped the survey layers.
       
      I have also attached the house plan, if that helps.
       
      Thanks for recommendations from this group, as I've watched numerous videos and couldn't find any that addressed this process.

      I spent several days creating a very ornate driveway gate for my personal residence.  It's 20'x5' tall with a rise to 7' in the center.  I've added it in the Symbols Library for anyone interested!

      I know this has been talked about before but I can not find it and I can't figure out how to do it again.
      I have a house drawing and I have the terrain drawn and I would like to orient the house differently on the terrain. I want to keep my house drawing square with my plan so it would need to be the terrain itself that has to rotate. I can rotate the terrain perimeter but that doesn't rotate the elevation lines etc. When I select the perimeter and all the elevation lines, i am not able to rotate the whole thing.
