How to Get Rid of Duplicate Shadows in Sketchup

Featured image_How to Get Rid of Duplicate Shadows in Sketchup

We recently received a question on how to get rid of duplicate shadows in Sketchup. If you look at the picture below, you will notice this model is showing a light gray shadow with a darker gray one underneath. If you have ever experienced this issue or something similar, keep reading to see how you can fix it!

View > Shadows. In order to see if you are experiencing this problem, you must first make sure that “shadows” are enabled. To turn them on, navigate to “view” and select “shadows.” If they are already enabled, there will be a checkmark next to it.

Window > Default Tray > Shadows. You also want to make sure you have it selected in the default tray. To do this, simply navigate to “window” > “default tray” and click on “shadows.” Now there should be a tab in the default tray where you can edit them.

Understanding Duplicate Shadows in Sketchup

The reason Sketchup displays two separate shadows is that the model essentially has two. For example, if you were to model a building with no terrain or ground plane you may only want to show one shadow option. You can edit these and other options in the default tray.

Edit Shadows. Open the “shadows” tab in the “default tray.” You will see a variety of sliders and options you can edit. The “light” slider changes the opacity. The “date” and “time” sliders will change the angle of them. If you want longer shadows, choose a winter month. If you want shorter ones, choose a summer month.

For now, we will focus on the “display” options. These change where the duplicate shadows in Sketchup are being cast. For example, “on faces” means they are cast on geometry and “on ground” means they are being cast on the ground plane. In this model, if we uncheck “on ground,” the light gray one goes away.

You will notice that the edge of the shadow gets cut off because there is no geometry drawn beyond the ground plane. If you want to still show the entire thing, just simply extend the ground plane until the entire outline can be seen.

Alternatively, you can uncheck “on faces” and bring everything up to the ground plane of Sketchup. This way, you don’t have to extend anything you’ve already modeled and the shadows will be cast evenly on the ground plane. Just make sure the base of your model is aligned with the ground plane(which starts at the world origin) to ensure they line up correctly.

    In the NCARB ARE 5.0 handbook they reference Fundamentals of Building Construction: Materials and Methods in both of their example questions for cost estimating. Unfortunately there isn’t a specific chapter on cost estimating, it’s woven throughout the content.

    What is the best reference for cost estimating for PDD.

    Deciduous trees should only be used for shade (especially in temperate climates). Deciduous trees lose their leaves in the fall and will have little protection against wind in the winter when it is most needed. Likewise, the leafless trees allow solar heat gain in the winter when it is desired, and shade in the summer.

    Coniferous trees are only to be used to block wind and views. Since they don’t lose their needles, they work great for these two items year-round.

    Hello. My name is Shahid. This comment is for anyone who would like to reply. On the Siteplanning test. To block the wind, can you use a Deciduous tree or must you use a Coniferous tree?

    Hi Tony,

    I need to take 5.0 PPD & PDD. Do you plan on posting notes such as “Caroline’s Notes” that you had posted for the various 4.0 exams for either of those sections? I found those notes to be some of the best resources in studying for the 4.0 sections. If so any idea when? Thanks

    Hi Tony,
    Any updates on the SS exam ? If there’s an expected release date ? Thanks

    Paige,

    We are releasing practice exams for the SS exam later this fall.

    Best,
    Tony

  26. Paige October 4, 2016 at 11:34 am #

    Will you have SS questions on here at some point?

    Great post, very helpful with the lists of suggested materials, I just passed CDs in July and am taking PPP in November so I definitely needed the list.
