Welcome to the third video in a series on drawing the garden bench.
We have up until now we’ve drawn the back and front legs drawn.
I’m going to draw the upper back support next. I don’t know exactly where it goes that will be determined by this arm
But I think I will draw it first.
Let’s get started
The upper back support is 29” x 3 ½” with a ½” bevel on the top.
I’ll draw it and place it with the rectangle tool. Now for the bevel.
I’m going to draw a line and move it down ½”.
Then I’m going to draw another line and connect them up.
Now move the rectangle down a ½” and draw the outline with the polygon tool.
Select both objects and go to modify and Add Surface
There we go
What I’m going to do is bring it up, set it on the leg, make sure it is on the leg
Then I will use the rotate tool and rotate it back.
And as a last touch, because of the fill we can tell it’s not a 3D object yet so I will extrude it to 1 ½”.
Now I am going to go to plan view.
I’m going to bring my back over here and draw a line that I can mirror off of.
Select the back support the mirror duplicate tool, click on the midpoint of the line draw a vertical line and wa-la the right leg appears.
Now it’s time to draw the arm support. Let’s go to the parts list. The total length is 25 ½” x 5 ½” so I think it makes sense to draw it in plan view.
Let’s go to plan view and draw the arm with the rectangle tool.
Now I have to do some chamfering, so let’s go back to the parts and look at what we need.
I have a 1” chamfer on each end here and an 8 x 2 ½” and a 1 ½” x 4”
So let’s chamfer the arm with the chamfer tool, set the first line and second line at I” and 1”.
Now let’s do the little triangle. It’s 2 ½” x 8”. Now I’ll move it over and attach it to the corner.
Select both objects and go to Modify>clip surface, and delete.
Now finally 1 ½” x 4” and I will change the insertion point to the right corner and repeat the process.
Looks good but there is one more thing we have to do and we can’t do it in 2D.
Let’s take a look at the arm.
Now if you notice it is 4” here but if you look at it in a side view it goes over ½” and the other one does the same.
We have to do this in 3D Let’s go back to our model in plan view and extrude the arm to 1 ½”.
Now I’m going to move it so nothing is behind it and I’m going to go to right view, and there is our arm on the ground plane.
Now I will make that little ½” triangular cut out.
Remember, we are in 3D so I’m going to draw the 4:12 triangle again
Now I’m going to extrude the triangle to 2”. Let’s look at it in plan view and we can see that the triangle looks like a rectangle in plan view.
I’m going to line up the top right corner right there.
I didn’t quite get it .
Now it’s right on the corner.
Notice how my triangle, my wedge is sticking out beyond the arm so that when we select both objects and
rather than going to modify and clip surface we will go to the subtract solid tool.
Here is the way it works – the item that has the red highlight will be the object you will keep.
So we want the arm highlighted because we want to keep it. The one un-highlighted will go away.
Now let’s look at it in side view, and you can now see the angular cut out.
Now let’s go to the right side view, it is lying on the ground, I will select the arm, command M and set 22” in the y axis .
Now I’m going to pull this over with the shift key held down. Now take a closer look and get it lined up right on the edge there.
If we look at our print the front of the arm rest lines up with the front of the seat. And the seat front is sitting out 2” in front of the front leg.
So with the leg selected I select control M and move the arm -2” in the x axis.
Now we need to get it lined up side to side.
Let’s move it by grabbing it right here, hold the shift key down and place right there.
Now I’m going to draw a mirror line, select the arm and mirror duplicate it. Now our arms are in place.
Now we have to move the back supports into place.
This edge of the back support has to line up right here and the bottom of the back support should line up with the bottom of the back leg.
So I’m going to draw a line from here to there.
Then I’m going to extend the line with the shift key held down until it touches.
Now I will place a locus point at the bottom intersection and delete the line, because you may forget that it’s there.
Locus points don’t print so we can bring the back support down to the locus point and just leave it there.
It lines up perfectly. Bring the other back support down.
Let’s look in right isometric with some rendering. Now all we have to do is put in our seat and back boards and the little triangular arm support.
Let’s go to plan view. The seat front is 43” x 5 ½” with two 2” chamfers.
We know how to do that. Rectangle tool, 43” x 5 ½”, Chamfer tool 2” and 2” and finally extrude to 1 ½”.
Now I’m going to grab it right here and line it up right there.
Now I’m going to go to the right view again and move the seat front up so that it sits on top of the front leg.
Next I’m going to draw the seat boards with the rectangle tool 3 ½” x 1 ½” and we will make the insertion point in the bottom corner there.
And we will insert it right there.
I am now going to rotate it. Also my seat front needs to be adjusted down.
Now let’s duplicate the 2 x 4 and move it down duplicate another one move it down.
Now we need to extrude the three seat boards to 48”.
Let’s move them in place by grouping them and move them to a mid point on the seat front.
Let look at it in side view, somehow they moved down, let’s move them up right there.
Now let’s do the back boards and what we can do is ungroup the seat boards and take this guy and duplicate it and hit command L.
Now we can place it against the back support. We need three duplicates, which I will put in place.
That looks good, and because these are duplicates of the seat boards they are lined up properly, side to side.
Now to isometric view with some rendering. The seat boards are hollow so let’s give them a fill. And there is the finished model.
In our next tutorial we will be taking the bench apart and making our parts sheet.
See you next time!
