3. Acquiring a Map To start off, you must get a map of the area you’re trying to conduct the analysis in. It can be either from Google Maps, NYC Oasis, NYCityMap, or etc. Project Tour • Take a Tour Project Outline • Acquiring a Map • Placing The Map • Resizing The Image • Shadow & Location • Casting The Shadow & Time • Region Fill • Hiding The Shadow • Unhiding The Shadows • Transparency of The Shadows • Annotating The Shadows • Placing It Into a Sheet Wrap up Use Print Screen on the keyboard or a program, such as SnagIt to save the map. NYCityMap and Oasis are the most clear of the bunch.

4. Placing The Map Once you’ve gotten your map, you can now place it into the project. You should do this on the Site Plan View. Project Tour • Take a Tour Project Outline • Acquiring a Map • Placing The Map • Resizing The Image • Shadow & Location • Casting The Shadow & Time • Region Fill • Hiding The Shadow • Unhiding The Shadows • Transparency of The Shadows • Annotating The Shadows • Placing It Into a Sheet Wrap up Go to the Insert tab and click on the image button. Once, the image is in, your screen should look similar to this.

5. Resizing The Image Project Tour • Take a Tour Project Outline • Acquiring a Map • Placing The Map • Resizing The Image • Shadow & Location • Casting The Shadow & Time • Region Fill • Hiding The Shadow • Unhiding The Shadows • Transparency of The Shadows • Annotating The Shadows • Placing It Into a Sheet Wrap up There seems to be something wrong now. The image seems to big/small for the model that you’ve created. You’ll have to resize it to fit properly or else the analysis won’t work. To properly resize the image, use the move tool to place it on a corner and resize it like that. When you click the image, a X should appear, which will let you size it properly.

6. Now time for some Sun. [1] Go to the bar at the bottom of the screen that has an image of a Sun with an X on it and click it. Then sun settings. This window will pop up. [2] Tick the “Still” and then [3] “Winter Solstice” in the presets.

[4] Click the “…” in the Settings section and this window should appear. [5] Input your address and search for it. Then OK.

7. Casting The Shadow & Time Now that you’ve set up the location and the date, you’ll now be able to cast the model’s shadow. At first nothing will appear. You’ll have to click a button next to the Sun Button on the bottom for it to show. Project Tour • Take a Tour Project Outline • Acquiring a Map • Placing The Map • Resizing The Image • Shadow & Location • Casting The Shadow & Time • Region Fill • Hiding The Shadow • Unhiding The Shadows • Transparency of The Shadows • Annotating The Shadows • Placing It Into a Sheet Wrap up You can also alter the shadow by changing it to the desired time. I’ve changed it from 12:00 PM to 1:00PM in the Sun Settings.

8. Region Fill Let’s put the time back to 12:00 PM for the analysis to be effective. The next step is to Region Fill the casted shadow. You can find the button in the Annotation Tab. Project Tour • Take a Tour Project Outline • Acquiring a Map • Placing The Map • Resizing The Image • Shadow & Location • Casting The Shadow & Time • Region Fill • Hiding The Shadow • Unhiding The Shadows • Transparency of The Shadows • Annotating The Shadows • Placing It Into a Sheet Wrap up Once clicked, the ribbon should turn into this. Use the Line tool to start tracing the shadow. Zoom in to accurately trace it. Your trace should look similar to this, also in the properties bar, select the Solid Black Region Fill. It might be on something else by default. Then click the Green Check Mark to finish.

9. Hiding The Shadow The shadow should now look like this. Hiding the Shadow is crucial to the process of tracing a new one, so it won’t be in the way. Right click the Shadow that you’ve traced and go to Hide in View, then Elements. The shortcut to this is (EH) by default. Project Tour • Take a Tour Project Outline • Acquiring a Map • Placing The Map • Resizing The Image • Shadow & Location • Casting The Shadow & Time • Region Fill • Hiding The Shadow • Unhiding The Shadows • Transparency of The Shadows • Annotating The Shadows • Placing It Into a Sheet Wrap up Once hidden, it’s now time to start a new shadow. Go back to the Sun Settings and change the Time. I’ve changed it to 1:00 PM. Trace the Shadow with the Region Fill command again, then hide to start another.

10. Unhiding The Shadows Project Tour • Take a Tour Project Outline • Acquiring a Map • Placing The Map • Resizing The Image • Shadow & Location • Casting The Shadow & Time • Region Fill • Hiding The Shadow • Unhiding The Shadows • Transparency of The Shadows • Annotating The Shadows • Placing It Into a Sheet Wrap up Now that you’ve hidden them all, you’ll need to unhide them now. Click the Reveal Hidden button near the bottom and your screen should look like this. Right click on one of the shadows and go to the Select All Instances, then Visible in View. This will select every Shadow that you’ve created. Then right click again, Unhide in View, then Elements. Now your Shadows should all be visible in the regular view.

11. Transparency of The Shadows The final step in all this is to change the Shadow’s Transparency. Select all the Shadows again, Then right click, Override Graphics in View, then By Element… This window should pop up. Go to the Surface Transparency section and slide it to the desired value. The higher the value, the more transparent the shadow will become.

Go back to the Annotation Tab and hit Text. The results should look like this.

13. Placing It Into a Sheet Rename the Site to Winter Solstice and drag it into the Sheet. This is the conclusion to this tutorial.
