The Scale Feature
 |  Igor Idzik

Welcome to the Scale feature, an article dedicated to showing all of the ins and outs of the tool, as well as its applications that may not be immediately obvious. The Scale tool - as its name suggests - allows you to change the size of objects or their regions.


As mentioned above, to scale any shape or any of its regions, you need to select them first. To do it you have to click on the object in the grid itself or select it in the Object Management section in the right-side panel if you want to move the entire model. If you'd like to scale its regions, you need to select them on the Interactive Rectangle. You can choose from Face, Polygon and Edge Selection. You need to remember though that scaling a region of the figure will change the object's geometry.

Once you select an object or its region, you can proceed to start scaling it. As usual, in SelfCAD, there are two ways to do that - you can either type in the values into the text-boxes, or by dragging gizmos in their respective directions.

Below are the Advances Settings of the Scale tool. After expanding the drop-down list, you’ll notice all of the available options.


The first option is called Symmetry, which - as you can imagine - helps you with keeping scaled object symmetrical. When you select this option, the software will equally increase or decrease the size of the model in both directions on the given axis.

Following is the option called Keep Proportion, which is - as most tools in SelfCAD are - rather self-explanatory. While Symmetry changed the size equally on only one axis, the Keep Proportion setting changes the size equally on each of the axes.

At the bottom is the option called Manual gizmo position, which you can use to change its position.

When you choose the Region Selection, you’ll notice that the Individual Transformation option appears in the Advanced Settings. This option allows you to scale each selected region independently of each other.

Another option available while scaling regions is the Local Transformation option. It will move and rotate the position of the gizmo, which, in turn, will grant you the possibility to scale selected regions in different directions.

And that's all there is to the Scale feature. After reading this article, you should know the basics of the Scale tool and how to use it, know about its different applications and how to use and customize its advanced settings. Of course, the graphics shown here were just examples, and using this tool on other shapes will give you slightly different results, but its underlying principles will always stay the same. That's all I had for you. I wish you success in your future projects. See you, and stay tuned for more content to come!
