Topography Of A Site

[Debra Necochea]

Iam trying to make a site model of an area of a city that is roughly 6000ft by 6000ft or 2km by 2km (probably slightly less). I would like the site model to include the topography of the site (elevational changes) as well as the buildings and roads of the site area.

BTW: As I said I bake my beans solely via C# code (and I never use any plug-in [other than K2]) so I have no idea what Elk and the other one do. Meaning that I may be the worst person imaginable to outline a working (and fast) strategy on that matter.

The main difference between Elk and Gismo, perhaps, is that, for Elk, you need to download the information yourself and point Elk to that information. Gismo needs a point of interest and will then download the information by itself.

A couple of years ago, my first few days on a new web performance project werealways slow going. So many false starts, tedious workflows, and a complete lackof efficiency really made it difficult for me to find momentum. All through nofault of the client or the project, but through huge flaws in my own approach.In a bid to address this, I introduced a new tool into my arsenal so thatI could hit the ground running much faster, and get answers to my clients muchsooner.

By capturing and comparing the behaviour of these pages alone, we canimmediately begin to build up a representative picture of the state of the wholesite. And while we may not capture outliers this way, we can still audit thosein isolation as a separate body of work if required.

The whole point of the exercise that follows is to allow me to move quickly,spotting patterns from afar, and not having to do any slow or meticulous workyet. I want to be able to form hypotheses and draw conclusions without viewinga single URL or a line of source code. That work is what comes next.

Firstly, I want to compare whole pages at a time. Immediately, I can seethat the PLP is by far the worst offender. Almost all of its bars are higherthan other pages. This means that I will likely end up giving it a little moreattention than the others. Next, the other three pages are pretty similar withthe homepage being marginally worse.

The next thing I want to focus on is deltas between First Paint and FirstContentful Paint. FP is defined as the first pixel, no matter what it is,being put on the screen. FCP, on the other hand, is the first image- ortext-pixel rendered to the screen. Note that most pages share near-identical FPand FCP? This is a strong suggestion that a page is either:

Being able to gather this many clues so quickly sets me up incredibly well aheadof digging into the project fully; it tells me exactly where to look first. Thisentire exercise is a great way of knowing where to start, which was always oneof the most tricky parts of the process for me.

We have topography in our new construction phase, and there are several site pads to manipulate a variety of 'platform level' in a play ground. We have placed the site pads and used pick edge to create pads that are adjoining.

Do not use Pick Lines when you create the Pad boundary of the second Pad. You must copy paste the boundary of the 1st Pad and edit/trim to create the second Pad, at least do it for the overlapping edges.

This is probably one of the top twenty most posted questions. I think @ToanDN would agree. If you Google using the keyword "slivers", instead of "slithers", I think you'll get an bunch of hits that help you.

I have a solution, we found the new topography had some rather extreme points, and Revit couldn't resolve the topography, when some of the topo points where deleted from the locations where the site pads had been created the problem was solved.

I have a site survey that show elevation points, rather than contours. Is there a way to create a ground surface with these points? The end result desired is just a smooth surface that changes grade with these points, such as the gentle slope from a lane to the house. I've input a PDF of the survey into my VW drawing and now can't figure out how to input the elevation points into something that VW can convert into a ground surface. Any tips would be appreciated.

Thank you. I think that worked. What should be done about the landscape where the house sits? Would I need to somehow create a void or excavate where the basement sits in the landscape? Is there a way to easily carve these voids out of the topography? Thanks in advance.

Hi, Have your surveyor provide you with a .csv file. this data is the rl and eastings and northings from their survey data. They may need to change the file extension to .xyz or zip it up as the computer doesn't like to send program files.

I created my contours but I can't see my original survey under the contours. I would like the contours to show over the Survey with the elevation stakes showing as well. I have tried different visability settings but can't seem to get it to show the way I want. Does anybody have and suggestions?

You can make the Site Model transparent in Top/Plan in order to see objects underneath. Setting the fill to none in the Attributes Palette is one way to do this but will render the Site Model transparent in section viewports so a better way is to disable 'Draw Site Border' in the 2D Display settings.

A topographic map represents a three-dimensional landscape in two dimensions. It typically shows various landforms, including peaks, valleys, ridges, rivers, and lakes. These maps can also show you whether you will be traveling uphill or downhill on a particular road or trail, showing the steepness, slope, and elevation of the area through topography lines.

Elevations on a topographic map are marked with contour lines (also called topography lines), which connect points of equal elevation. Imagine walking around a mountain in a circle, never going uphill and never going downhill but staying at the same altitude. If you traced the path you walked, you would have a contour line on a map.

The shape of the topography lines can tell you the shape of the landforms in a particular area. For example, concentric circles show a peak, with the smallest circle marking the summit. Contour lines that are close together indicate that the land is very steep, while contour lines that are spread apart show that the land is relatively flat.

Mobile mapping systems: Again, this is more of a professional technique. It involves mountain mobile mapping systems onto a vehicle or drone to capture data while moving through the site. An accurate 3D models of the terrain can then be developed.

Did you know that the U.S. Geological Survey began surveying land in 1879 to create commercially accessible topographic maps? There are more than 54,000 in existence. We at MySitePlan use the information from these maps to add contour lines in two to five-foot intervals on your custom site plan.

So, the next time you step onto the road less traveled, you may start to see those rolling hills, valleys, and streams a bit differently and understand how every elevation and even the soil might affect your next building project.

Then, with the wall selected, run Landmark > Architectural > Fit Walls to Objects. Choose the option to fit the bottom of the wall to objects on the layer that contains the site model. Also check the box to include site model objects.

If you want to model the wall more how it would be built, you can use the Landmark > Architectural > Create Stepped Wall command. Your wall needs to start at the correct height, and have the bottom elevation at the required depth below the surface of the site. Then, you can choose the step length to create regular steps, or have them follow the terrain.

You need both Lock Profile Plane and Fix Profile selected to get proper results. Unfortunately, when I just tried it I got an error message. I am using VW 2017 and I notice that post was from 2016, so all I can think of is VW changed something in the Extrude Along Path code that introduced a bug. Hopefully the bug is fixed in newer versions of VW. If not, I figured out a work around that works consistently, at least with my set up anyway. The fix is to manually position your profile/rectangle at one of the endpoints of your nurbs path, positioned how you want it (I use the bottom midpoint). And the profile/rectangle has to be set to layer or 3D plane. And it has to be manually rotated to be perpendicular to the path. This all sounds complicated but it is actually quite easy and fast once you get the hang of it. After you drop to surface, enter the group it creates, switch to a right ortho view, and draw your profile in place at the endpoint of the nurbs path. Then switch to top view and move it again over to the same endpoint. Then use the rotate tool to rotate in place so it is aligned parallel, and on top of, the path, then just hit command L (control L on Windows) to make it perpendicular to the path. It sounds confusing but really isn't once you wrap your head around it. If it doesn't make sense to you I will whip up a little step by step with pictures to help. Here are a few showing how I rotate the profile/rectangle into place. And the finished product. Here are the steps:

Glad you were able to get it to work. I agree this is a very useful capability to have, especially for schematic/conceptual designs with hedges, rock walls, some fences, even regular walls, maybe even berms. I'm pretty sure I remember using Extrude Along Path with 3D paths in the past, so it must be a bug that got introduced since v 2016 and somehow broke it. Tamsin, maybe you could report it and get it on the short list to fix? It doesn't seem like that hard of a fix. Thanks.

is there any way to add Terrain to fit to existing elevations. I have a Barn home built into many layers and I cannot seam to get the site terrain around it, not in it and correct:-( The yard comes up around our sunroom then down, and off the lower gym, off pool, dropped down dramatically from barn-stone wall.
