Greetings to all. In today's class,
we will draw the handrail for our stair.
As we know the stair is divided into three sections.
So, for this class,
we will draw the handrail for the first section.
Here we will use a line tool,
circle and rectangle in the shape tool and a follow me function. Let's get started.
After drawing the stairs,
we draw the handrail.
We first add a new layer,
give it a name of handrail.
Then we can choose this as an eighth layer.
We know from the fore plan that the distance between
the handrail and edge of the stair is seven centimeters.
So we draw the guide line there.
We input seven.
After placing the guide line,
we use the line tool to trace the line on the stair surface.
Then, from the line midpoint we draw another line up wall for 80 centimeters.
We repeat the process for the upper step.
Once we have both verge goal lines done,
we can make them with a line.
Here we can see the shape of the handrail now.
Next, we extend the line in the lower part.
We do this because the handrail does not start from the first step.
Then we draw the vertical line from the lower step
H. The closed polygon will generate a path,
so we erase it.
From the intersection of these lines,
we draw a ten centimeters line along the green axis.
Now we can erase the actual lines.
We repeat this process on the top of the stairs.
Here, we extend the handrail line and draw a vertical line from
the last step H. Then we delete the plan.
From the intersect point we draw a 10 centimeters line along the green axis.
Now we can erase the actual lines.
Now that we have the handrail shape,
we use these as a base to add the other details.
First, we draw a rectangle on the vertical plane of the lower step.
This is a way to draw something we cannot draw directly.
We input 6, 12 to get our rectangle.
Then we use the move tool and select the upper midpoint of the rectangle.
And then we move it to the start point of the handrail.
This will be the handrail shape.
Next, select the path of the handrail and click the Follow me tool.
Then we click the rectangle.
The rectangle will follow the handrail lining.
After this, we can erase the actual lines.
This is a powerful function in SketchUp that make complicated drawings simple to do.
So we've kept some experience with SketchUp,
we can get professional results with a few simple moves.
Next, we hide a stair layer and a fore plan layer.
Now we focus on handrail.
We select the whole handrail but we need to be careful of not to choose the lines below.
Then we make a group, after grouping,
we open the stair layer and erase unnecessary lines.
Then we draw a handrail baluster,
we use a Circle tool to draw a circle from this point.
Then we input 1.25.
Moreover, we push it until it intersects the handrail.
We should not make the baluster shorter than the handrail
because it will expose and unclose the part.
Once the baluster lense is established,
we are done with it.
Now, we clear the baluster three ties and group it.
With this group, we can start copying and creating each step baluster.
We use the Move tool to copy the group.
Use the tape, take stair corner as a reference points.
The work will be easier.
Once we are done copying,
we input file X,
to draw five baluster at one time.
To make the operation clear in future lessons,
we group these five baluster.
Now we have drawn the first part of the handrail.
Today we learn how to draw a handrail.
It look more complicated than what it is.
During the next classes,
we will use the same procedure.
And we will learn more detail about the handrail.
Let's stop drawing for now.
