Create a 3D Site Plan Using CADMapper and AutoCAD

Need to quickly create a 3D site program in AutoCAD?

Hither's how to do it.

This tutorial covers the following information:

1. Setting up a 3D site in CADMapper

2. Converting Units: Metric to Imperial

3. External References: Separating Layers into Drawings

Disclosure:

CADMapper is a website that can save architects, designers, and planners tons of time by automatically generating 3-Dimensional information for over 200 cities around the globe. CADMapper generates 3D models that can exist used with AutoCAD, Sketchup, Rhino, and Illustrator. To generate information for topography, buildings, and streets, CADMapper pulls data from OpenStreetMap.

I should start past maxim that my blueprint piece of work primarily involves the schematic blueprint phase of architectural design. I understand that site information should be field-verified past professionals in surveying, ceremonious engineering, etc. to ensure accurateness. The intention of this tutorial is to use CADMapper to create a basis for architectural schematic designs.

Setting up a 3D site in CADMapper

Step one: Find your site - Get-go with Google Maps.

I similar to start by finding my site in Google Maps. Oft, at that place is piddling data given that specifies coordinates or a concrete accost of a site. Searching for the site in Google Maps gives me a better understanding of what my site looks like from an aerial perspective.

In one case you discover your site in Google Maps, head over to CADMapper.com and blazon in the gauge address - or two intersecting streets.

CADMapper only provides vector line information, so it might be cumbersome to try to search for your site starting in CADMapper. Wait between Google Maps and CADMapper to hone in on your site, and create a box in CADMapper that captures the information you demand from your site. CADMapper is complimentary, but up to 1km of information.

E'er endeavor to capture more data than you remember you demand. Yous never know when yous might need the data in the time to come. Information technology'due south better to have information technology and not need it, than to need it and not have information technology - I've had to stitch multiple CADMapper files together earlier considering I left out some important data when I created my initial file, and it'south a real pain to get through that process.

Footstep 2: Turn on 3D Buildings

If you lot desire building height information, check the box for 3D Buildings. If edifice information is bachelor (which information technology oftentimes is in big cities), CADMapper will create mesh geometry of buildings in the CAD file. You can specify "False Height Data", in which CADMapper will generate buildings without top data to a value that you specify. Not a necessary step, but information technology can yous save drawing time.

Footstep three: Select 3D Topography, topography contours spaced at iv meters.

It's good practise to just collect as much information as we can get, early in a project. The lowest spacing that CADMapper volition generate for contour lines is 4 meters, which should be plenty of information to get you started in your design.

Pace iv: Route Geometry, Select "Outlines"

CADMapper provides options for generating road graphics. Roads can exist depicted as single middle-lines, outlines, or mesh surfaces. If you intend on using this site file for fabrication, such as 3D press or laser-cutting, I would advise choosing an choice that best suits your needs. For this tutorial, selecting "Outlines" will provide graphic separation betwixt types of roads, and permit like shooting fish in a barrel scaling of the drawing in AutoCAD. Additionally, "Outlines" is a adept option to choose for laser-cutting site models.

Change the road dimensions to specific dimensions: I recommend the post-obit:

• Highways: ten meters

• Major Roads: 8 meters

• Minor Roads: half-dozen meters

• Paths: 4 meters

Step five: Generate the CADMapper File

If everything is set to your liking, click on "Create File". It will take a moment to generate the file.

Once the file is generated, you tin examine the map in 3 views:

• 3D Axonometric View

• 2d View

• Topography

At this indicate, select download. The file will download equally a unmarried .nothing, containing ane .dxf file that yous tin open up with AutoCAD.

Converting Units - Metric to Imperial

Past default, CADMapper exports units in meters. For our purposes, nosotros demand to convert meters to feet.'

Step one: In the "Units" Menu, Change 'Decimal' to 'Architectural'

Blazon in command, "UN" to open the Units menu. Change 'Decimal' to 'Architectural', and 'Millimeters' to 'Inches', respectively. Notation that just changing the units will not modify the calibration the drawing. For example, 2 meters volition be converted to 2 feet, which is incorrect.

Then, we'll need to scale the cartoon after changing the units from metric to royal.

Step 2: Verify the Distance of a Route

Use the control "DIST" to measure the distance of i of the roads generated by the CADMapper file. It should read as one of the measurements that was specified on the CADMapper website. For this case, the road is vi meters.

Stride iii: Calibration the Drawing

If the road distance is 6 meters, it will need to be scaled to 19.685 feet (because 1 meter = iii.28084 feet) after changing the Units from metric to imperial.

Depict a polyline (command "PL") off to the side of your drawing in model space somewhere. Below that 6 meter line, draw a line of distance, 19.685.

Use control "AL" for 'Align', and select EVERYTHING in model infinite. Deselect the (19.685) line. We want to calibration everything in the drawing except that line.

Select the first point of the (half-dozen units) line, and the showtime indicate of the (xix.685 units) line. And then, select the second point of the (vi units) line, and the second point of the (19.685 units) line.

When prompted to 'Scale', select Aye.

If washed correctly, all of the elements in the drawing volition have scaled with the (6 units) line, which now matches the distance of xix.685. So now, when the Units are set to "Architectural" and "Inches", all of the roads should read as the equivalent imperial measurement.

External References: Separating Layers into Drawings

CADMapper conveniently sorts drawings elements into separate layers. This is useful in terms of system, nevertheless, we should gear up our drawings in a style that allows multiple people to piece of work on them. This may not be necessary for your particular project, simply it'south skillful practice to learn the conventions of creating external references to keep file systems organized, and to allow the potential for multiple people to work on a single projection.

Streamlined file systems = saved fourth dimension on drafting work. And saving drafting fourth dimension will open upwardly time for more important stuff, like designing!

Here'south how to quickly create external references from layers:

Step 1: Open the Layer Menu

Blazon "LA" to open the Layer Menu. Freeze all layers, then unfreeze the first layer that you lot desire to convert into an external reference. In this example, we'll commencement the the layer called "buildings".

Next, type "Select" and "All" to select everything on that layer.

"Copy Base" with, CRTL+SHIFT+C, so specify the origin signal as 0,0,0 (x,y,z, respectively).

This is of import, because copying the data with the origin signal will permit you lot to bring all of the drawings into the new "Master Cartoon" at the same point. This will ensure that the drawings are lined upwards correctly, maintaining accurateness in the information.

Step 2: Create the "Master Drawing"

Open a new drawing. This will get the "Principal Drawing", which will hold all of the xrefs that we will be creating for each layer. The "Master Drawing" volition expect exactly like the original file containing all of the individual layer information. The benefit of setting up a master drawing this manner, is that multiple people can work on individual files within 1 project.

For case, one person can work on the "Buildings" layer. Another person can piece of work on the "Roads" layer, and so on.

This is non only convenient for grouping drafting projects, but it will assist y'all build a consistent file system that can be applied to a number of different programs outside of AutoCAD. It'south just a system of file linkage, and these types of systems offer the about flexibility for organization, and drafting workflows.

One final note: the "Principal Drawing" should serve as a file for reference, and should not be drawn on or referenced to other drawings. Changes made on all of the other external references will reflect on the Primary Drawing, all the same, changes made on the Master Drawing will not reflect on the linked external references. It'southward a one-way street, and maintaining this system volition ensure that your project is make clean and organized.

Practiced luck!
