I would really like to learn more about Blender and I’ve been doing some basic projects off of websites, but a lot of times you need a “middle mouse button”. I only have a scroll button in between my right click and left click buttons, does this mean I have to go buy a new mouse?
Step 9: Select all vertices (press [A] twice), and scale everything in the x-dimension. To do this, enter scaling mode (type s), then constrain scaling to the x axis (type x) This will lock the scaling to only one dimension.
You can also constrain scaling to two axes by pressing Shift+the axis you don’t want to scale.
No MMB required.
Generally there’s a way around using the middle mouse button if you don’t have one.
That’s the normal function of the MMB, which means yours works as it should. But once you are in Scale mode (after pressing the “S” key), then it should restrict the scale axis.
Otherwise, just use the method mentioned by Orinoco.
