How to Soften Edges and Round Corners in Sketchup

Featured Image_How to Round Corners in Sketchup

When modeling and rendering objects in Sketchup, it’s important to add details that will create a realistic final product. In this tutorial, we’ll take a look at how to soften edges and round corners in Sketchup! This can be useful when trying to make three-dimensional objects look more realistic and less computer-generated. Simply curving an edge or corner will give an object more depth and make it look more convincing than a perfectly square edge. With a few easy steps, we’ll show you how you can turn a flat looking surface into a more realistic looking object!

For this example, we used a basic cube (disguised as dice). You can see in the rendering before we round the corners the shapes look flat and hard. Adding a rounded corner and edge will give the dice a more realistic look that we are familiar with.

Adding Round Corners in Sketchup

Round Corner. We did this by using a Freedo6 plugin called “round corner.” This plugin is useful for quickly rounding corners in Sketchup and adding unique beveled edges. If you don’t have the plugin installed, follow these steps:

  • Window > Extension Warehouse. Navigate to the “window” tab and select “extension warehouse” from the dropdown menu. The extension warehouse window will appear. From here, use the search bar to search for “Freedo6” plugins or “round corner.” When you find the right plugin, click on it to install.
  • Install. When you select a plugin, you will notice a red “install” button in the upper right corner. Click on that to install the plugin. Once you have the plugin installed, you can access it from the top left corner of your toolbar in Sketchup.

The plugin comes with three different options, a beveled corner, a sharp corner, or a round corner. In order to add round corners in Sketchup, we are going to use the round corner option. You may use the other options for more complex shapes like a counter top, wood trim, or picture frame edge.

parameters of adding round corners in Sketchup

Rounding Parameters > Offset. Double click on the object you want to round the corners of. Then select the “round corner” button from the Freedo6 plugin. Under the “rounding parameters” options select the “offset” button to set the offset amount. Type the desired amount you want to offset the corners by and hit enter. You may have to experiment with higher or lower values until you get the look you want. Left-click to exit the “round corner” tool.

Render. If you are using Vray to render your objects, you can use the Vray window to see how the objects in Sketchup will look when rendered. You may have to re-render the image after rounding the corners to get a more accurate preview.

    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.

  19. Spencer August 30, 2017 at 1:15 am #

    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

  25. DesignerHacks October 4, 2016 at 12:11 pm #


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


  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.
