![]() You'll see a notification at the cursor that the inference is locked. The up arrow locks the blue axis, the left arrow locks the green axis, and the right arrow locks the red axis. Tap a directional button while measuring to lock an axis.In the figure, you see measuring tape aligned to the red axis. The measuring tape line changes color to match an axis colors when it is parallel to any axis.Tip: Here are a few tips to help you move the Tape Measure cursor through 3D space: Measuring Angles and Distances to Model Precisely SketchUp Hardware and Software Requirements.Using SketchUp Data with Other Modeling Programs or Tools.Modeling Terrain and Other Rounded Shapes.Using SketchUp’s Generate Report Service.Placing Movie Cameras in a Model of a Production Set.Developing Components and Dynamic Components.Adding Premade Components and Dynamic Components.Applying Colors, Photos, Materials, and Textures.Modeling Specific Shapes, Objects, and Building Features in 3D.Adding Text, Labels, and Dimensions to a Model.Modeling Complex 3D Shapes with the Solid Tools.Measuring Angles and Distances to Model Precisely.Offsetting a Line from Existing Geometry.Softening, Smoothing, and Hiding Geometry.Scaling Your Model or Parts of Your Model.Flipping, Mirroring, Rotating and Arrays. ![]() Dividing, Splitting, and Exploding Lines and Faces.Introducing Drawing Basics and Concepts.SketchUp 2021 - Frequently Asked Questions. ![]() Short reviews of the various science resources and curricula I have used with my own children.

Measure all the angles of your quadrilateral. Draw four dots, and connect them so that you get a ![]() Protractor. If you need to, make the sides of the anglesĦ. What is the correct angle measure for the angle she measured?Ĥ. Measure the following angles using your own That she had read the wrong set of numbers on the protractor. Tasha measured an acute angle, and got 146°. We need to read the lower set of numbers.ģ. Lined up the one side of the angle with the zero of the lower set of numbers, so So that one side of the angle lines up with one of the zeros, and read that set Numbers: one set goes from 0 to 180, the other set from 180 to 0. Which one you read depends on how you place the protractor: place it Take care to read from the right set of numbers. A protractor has two sets of
