Hello everyone
today I'll be demonstrating to you the first steps to a good landscape plan
Number one is minimalist workspace try to keep your workspace as clear as possible
with only your layers tab and your properties tab docked to the
Right hand side of your screen when you attach a file make sure that you've reduced the size to as minimal as possible
So that it doesn't slow down the hole drawing.
After that click okay, and make sure the unit sign in millimeters, you're attaching to the origin point
And then click OK ignore the scale and just click enter
I will show you how I scale the drawing using coordinates
Sometimes it's possible that you're given a very very old survey plan
And it doesn't have any CAD files just a printed copy of A4 Size with coordinates and
Measurements, we've probably don't even have a North sign and with the coordinates method you can find out the North
signs the measurements and the orientation of the drawing.
Before that we will fade out the drawing select a drawing and then right-click and properties
customize properties and then click on fade and
increase the fade-out
percentage
Make sure the drawing selected
You will have problem fading out if you don't select it
So then increase the up to 50%
Then we will plot out all the coordinates on the plan using PO, point command
just click on any way you want to put this point or you can key in your
Coordinates you want this point to be click on set size in absolute units
It's easier to adjust that way and for the point size set it to 0.1 and above.
You can adjust the size to your preference
Just click on the preferred point and click OK. You will see that the point has changed. Remove it
and then we will use coordinates to
Input the position of the point. Change the active layer to boundary line layer so PO, Enter
you need to have a dynamic input to be turned on for this exercise and key in the coordinates x and y
We key in the coordinates X as a positive number and Y as negative
seven eight zero eight zero one three four
Without a decimal point because the coordinates are all in meters and our draw is in millimeters.
so once you get in press ENTER and
The point will be positioned at the exact coordinates that we have keyed in just now
Now we'll go back to the drawing and continue to plot all the different
coordinates on the boundary line
whenever you start a new project remember to start on the boundary line the position of the boundary line.
The Northing signs, The important information of the drawing before you
Put in the design
If you're wrong on a position of the boundary line it will affect the distance of the perimeter
boundary planting because in
Some countries they require you to have a minimum
distance of greenery along the boundary line before any
structure can be
erected
so boundary line first
Another point I want to
Highlight is when you draw the boundary line using coordinates or any boundary line
use a thin line of
0.1 or
0.05
So that the thickness of the
Boundary line is not included within the area of the site
What happened one time was after we finished planting the greenery buffer along the perimeter we?
Were told by the authority that some of the trees are not within the green buffer, and we had to
Remove the trees and replant them again. I think this problem originates from
Boundary line is not accurate. This is also important when you need to submit the
green area ratio to the authorities and
If you're off by a little it can add up to quite a large area if it happens all
along the boundary line so
remember to be as accurate as possible when it comes to boundary line and
if you made a mistake
Check with your seniors
But honestly I think that
fresh graduates shouldn't be given the task to plot in boundary line and
Also be blamed for this heavy responsibility
because ultimately
This is a job that a senior Landscape Architect has to
Be responsible for or the architect has to be responsible for so at least now
You know what to look out for and how to be as accurate as possible and avoid any
Mistakes that can happen in the future
so going back to the coordinates, so this one this coordinate will be the last coordinate and
Just like the previous one a positive x and a negative Y
Removing the decimal point and let's check out our positions in order to check out a position
I will teach you a method to open up two viewports the command is written above and
Click on horizontal and ok and you will see two horizontal windows on your screen on
the top window zoom in so that you can see
the
important image and
Then the bottom window
Zoom in to the points you derive from the coordinate you keyed in. Now
we're ready for the align command type ALIGN enter and then select your drawing and
click on the first point and
Then click on a second point that the coordinates are referring to
And then choose an opposite diagonal point click on it
and then click on the second destination point
the coordinates are referring to
after clicking the second point type Y and Y for yes
This is to scale the drawing based on the two alignment points and once you're done
You will realize all the points are in place
Now that the points are in place we can easily draw out the boundary line using the points. In order to
Maximize our workspace. Let's change our viewports to
single viewport VPORT and then click single and ok
Now we will start drawing reference lines to check if they are all straight lines and to create nodes
From the first reference line we can see that the first part of the boundary line is an arc
It's not parallel to the reference line
Try to click as
Accurate as you can and
Then when you do your polyline you will be... you will snap to the intersections that you have created
You can help another line here, but I didn't do it when I was
Doing the tutorial
I click it at the end of the straight line and I start another line at end of the arc
New line, a new reference line
And then another new reference line. Oh, but it's so short so we can
do without
And there's another point there for us to snap so it's ok
And then we start another reference line and looks like this line is also an arc
It's not parallel to the reference line
We skip the short one and continue to the
next line
Looks like there are a few lines here, so
There's an arc here
We'll click here
And then there's another
Arc or line
Following this Arc
It's an Arc
So using a reference line we can change it we can check whether it's arc or straight line
Okay, now. We're ready to draw the boundary line. Change the color to blue
PL spacbar and
select the intersection
Use intersection when there's too many lines crisscrossing
so after PL spacebar, A spacebar for Arc and then D spacebar for the direction of the
Arc and then click on the midpoint of the Arc and then click on an endpoint of the Arc.
As before snap to the intersection of the two lines
Use ctrl(Win) or shift(Mac) right click to pick the intersection node
And in order to change from Arc to Line
Just type L Spacebar. L means line and
then
spacebar A for Arc and then sometimes you don't need to
click the midpoints, so you just click the endpoint and AutoCAD calculates the
Arc
From your first and last point and then continue to the next node
And then click on the end of the arc and
L spacebar for line
Basically you can repeat all the steps as shown previously of Line and Arcs
Over here, I'm looking for the midpoint of the Arc
Basically the most curved area of the arc and then click on the point
Snap it to the point
L spacebar
Snap to the intersection of the reference lines
and then final arc
This Ark seems like it has been adjusted so I will manually adjust it to
match the
existing
Boundary line on the image
So you will see later that this section of the boundary line is
Not smooth, and it juts out. Okay now, we're ready to delete the reference lines
We don't need them anymore. E spacebar Select and spacebar
Now we can change the color of the boundary line back to the color of the layer
And
Then bring to front so that it stays permanently in front of the drawing
And if you want to change the thickness of the line you can change it now
I remember to draw your boundary line with a thin with thin line. One point, I want to highlight is
Remember to keep the radius of the Ark
Generated by the AutoCAD when you draw it with the polyline
Because it will be the smoothest arc
And now you can come to check the North Point direction with Google Maps
