Types of Borders (1)

Before I continue with the drawing tools, let me first talk about the different borders around or in the objects we have drawn.
You will undoubtedly have noticed when you’re drawing, that you sometimes see a thin edge and sometimes a bold edge.
From now on, I will call the bold border as the main border, and the thin edge as the shared border. Just so you know what I’m talking about.
When an object is provided with bold edges, it  means that the object or the plane, call it what you want, is a separate object.
As you see in the image below on the left there are two separate objects that actually lie one above another, and if you see on the right an object that is divided into two planes, that is actually three objects.

When a surface is provided with thin edges, it means that this surface is part of a different plane.

 

If you remove a leading edge, then you automatically remove the padding from that plane (1).

If you delete a shared edge, this will combine the two adjacent surfaces together to form one surface (2).
To remove an edge, select the “Eraser” tool in the tool bar, move the mouse pointer (which is changed to an eraser) on to the edge you want to delete and click with the left mouse button.

 

To first select a main edge or shared edge, select the “Line” tool.
Move your mouse pointer over the intersection of both lines, and when SketchUp indicats the “intersection” point, click with the left mouse button (1).
Move the mouse pointer over the “end point” and click again (2).
The two main edges are changed to shared borders.
If you do not immediately find these points, it is advisable to zoom in on your drawing.

Sometimes it may be difficult if you choose to do this in two superimposed circles.
But the only thing you need to do is to click the “intersection” point, and then click the “End point” of the first line segment of the edge that you want to transform into a shared border.
To find the intersection you may have to zoom in very far. The easiest thing that you can do is to set  the scroll wheel of your mouse.

For those who still do not know what a line segment is, I have magnified it in the image.
As you know, a circle is divided into 24 standard line segments. If you did not know, read the previous lesson.

 

What we must remember

If you have two separate planes and want to combine them into one plane, you must first click the intersection and then click the “End point” of the line segment.
For both clicks, use the “line” tool.
