How to Scale in Sketchup to a Specific Size

how to scale in Sketchup

If you’ve ever been working hard in Sketchup only to realize something isn’t quite the right size, chances are you’ve probably messed around with re-scaling objects. It can seem daunting and you may think it requires a lot of calculations, but in this tutorial, we’ll show you a simple way to scale in Sketchup without using any math! We’ll also show you how to scale just a portion of your model without it affecting everything else.

Make a Box. First, use the rectangle tool to draw a square in your model. Then, use the push/pull tool to pull the square up and create a cube shape.

From here, some people may measure the edge they want to resize and figure out what proportion they need to scale the shape by in order to get the desired length. This will certainly work and you can read on how to use proportions here, but why not save yourself the headache? There is a much easier way to scale in Sketchup!

Scale in Sketchup the Easy Way

Measure. Triple click on one of the faces of your cube to select the entire shape. Select the tape measure tool and measure the edge you want to change the dimensions of by clicking once at the starting point and once at the end. Then, type the desired dimension in the “length” box in the bottom right corner.

Resize. Hit “enter” on your keyboard. A message will appear asking if you want to resize the model. If you only have one object in the model, you won’t have to worry about accidentally re-scaling other objects. Go ahead and click “yes.” If there are other objects, it will resize everything in your model. Here’s how you can avoid resizing everything in your model:

Make a Group. To better understand how scaling works with multiple objects in a model, go ahead and make a few more shapes. Right click on your cube and select “make group.” Duplicate the cube so you have two or three cubes that are different sizes. If you simply select an object outside of the group and resize from there, everything in the model will be scaled accordingly. To avoid this, double click on the object you want to resize so you are within the group. Then use the tape measure tool to type in your desired length and hit “enter.”

Click Yes. Once you hit “enter,” a slightly different message will appear asking if you want to resize the active group or component. Click “yes” and now only the group you selected will be scaled.

    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.

    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?
