How to Make an Angled Cut in Sketchup | Sketchup Q &A

Featured Image_How to Make an Angled Cut in Sketchup

In this Sketchup Q & A session, we’ll go over some ways of making an angled cut in Sketchup to answer Mats’ question, “how can I cut a tube in a 45-degree segment?” There are three different ways you can achieve this and we’ll show you all the steps and pros and cons of each one! This hack can be useful for piping, meeting corners, or creating details like trim and door frames. Go ahead and open Sketchup, draw a tube and let’s get started!

Method 1: Make an Angled Cut in Sketchup with an Object

Make Group. Once you have a simple tube drawn, the first step you want to do is to make it a “group.” Right-click on the tube and select “make group.”

Draw Cube. Next, use the rectangle tool to draw a rectangle or square and extrude it up using the “push/pull” tool. This will be the object used to cut the tube.

Rotate. Press “Q” to open the rotate tool. Click on the bottom corner of the face closest to the tube. Then click on the top corner to drag the face towards the tube 45 degrees.

Make Group. After you have rotated the face of the cube, right click on it and select “make group.” Then, move the cube so that it intersects and fully covers the tube.

In the toolbar, right click and make sure that “solid tools” is selected.

Subtract. In the “solid tools” section of the toolbar click on the button that says “subtract.” This will subtract the first solid from the second one you have selected. Select the cube object first and then select the tube.

This is a simple method, but it involves creating a few groups and it deletes the object you cut with. Another way to cut an angle into an object is by creating a plane.

Method 2: Make an Angled Cut in Sketchup with a Plane

Draw Rectangle. Use the rectangle tool to draw a plane that is perpendicular to the tube.

Rotate. Press “Q” to open the rotate tool and rotate the plane 45 degrees towards the tube. Place the rectangle so that it intersects with the tube.

Select All. If these are the only objects in your model, you can use the shortcut “Ctrl” + “A” to select all. If not, just select both objects.

Intersect Faces > With Selection. Right click on the selection and click on “intersect faces” > “with selection.”

Erase. Press “E” to open the eraser tool an erase the extra objects.

If you want the end of the tube to be capped off, you will have to draw one line on the outside and one on the inside. Then delete the inner circle.

This method is pretty simple and efficient, but it may get annoying to close off the ends every time.

Method 3: Make an Angled Cut in Sketchup with a Plugin

The last way to make angled cuts is by using a plugin called Eneroth Align Faces. It is probably the fastest method, but it currently costs $15.

Draw Rectangle. Use the rectangle tool to draw a plane perpendicular to the tube.

Rotate. Use the rotate tool to rotate the plane 45 degrees. Copy the rectangle and flip it along the red axis, or use the rotate tool to rotate the copy 180 degrees.

Move the plane copy so that it meets up with the original one, creating a “V” shape.

Select the tube and then mouse over to the “V” as a reference angle. Hold “shift” and click on the tube to make the cut. You can also use the other side of the “V” to make a cut in the opposite direction.

The cool thing about this plugin is that you don’t even have to have your reference angle in the same plane as the object you are cutting. You can also quickly switch the direction of the angle if you cut it the wrong way.

    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

  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.
