Hello people! Welcome to this video! I am going to explain you how to render 2D
graphic designs. If you find mistakes in voice pronunciation, correct us in comments.
First of all, we will work always with the

Very important in 2D drawings is the

selection acts just on one line and not on the whole polygon. Different is the

polygon, because

on each side, that you can use to edit your polyline properly.
more than one single point to keep constant the sides that are between such points
while editing.
To make one of the straight lines curved, just stare for some time on the small rectangles
until a list shows up. Go to
Actually when you draw a rectangle or a polygon, you are drawing a polyline.
The only difference is that the software helps you drawing them with
equal sides and angles.
You may not be able to move a polyline simply, since it doesn't have central point.
Just select the whole polyline and click on
one point and move where you like.
If you want to decompose your polyline or polygon into its single pieces of objects,
use the
one by one.
When you work with 2D projects or maps, it is very common to put parallel lines at
a defined distance from a point or an object. This is called
button. First of all, set such distance. You can enter directly the value or you can get
such by selecting two different points on your workspace. After pressing
you will have to select which object to put an offset. Once made it, you will add a parallel
line at the distance set. This does work with polylines as well. A new object will be
added at such distance kept constant, and such will be the same kind of object selected.
If you selected an arc, you will create a parallel arc, and so if you work with a polygon.
Let's now see how to fill objects inside. Below the Ellipse command, you will find
the

can add such just to a single object, or you can add it to an enclosed area made by
different objects, even belonging to different layers. You have two ways to add hatch
patterns. If you choose

by a single object, different objects on the same layer or different objects
on different layers.

be not created until an enclosed space is revealed with the points selected
If you are adding an hatch pattern, keep in mind that the filling stops at the first boundary
met. If you want to expand the filling, you have to click over these boundaries.
In case you mistake in putting any pattern, just use the command line to undo the
latest filling.
repeat the last step.
Notice that, if you fill more objects with one single command, you will create a single
hatch only. If you want to create hatch patterns separately, you have to fill each
object with a single command. So, for each one of them, you have to fill in, then press
the
repeat the process.
Hatch patterns just created are recognised through a rounded point on the centre.
Through that point you will move the pattern out of the objects of origin.
Be careful, because you can't put the pattern again on objects easily, unless you repeat
the Hatch command. When you move the pattern put, this becomes an objects aside
that you can edit like a polygon or a polyline.
As long as the hatch stays centered in the object, any editing applied to the object
boundaries will be applied to the hatch as well.
Whenever you need the

patterns too. Go to
It's needed just one side missing in the area to remove the whole hatch. If you select the
boundaries of a pattern aside, this will be directly removed.
Patterns can be modified in many ways. Select the pattern from the

size of patterns and color. Go to the first option on top and left to choose to put

This opens the window where you can fully edit your hatch or gradient.
Very important expecially in more complex projects are the
For each object you can select a color to recognize it better. In
you can further change objects such as thickness of lines, and kind of line.
Properties marked with
properties of the layer it belongs to. Each layer has its own name and color and each
object does belong to one and just one of the list of layers you have, that you can
check by selecting an object and staring at it for some time.
Layers are very important to work better with your project. When it is complex, you may
be in distress because of too many lines and objects communicating each other or too
much close. You may need to hide all objects you don't need temporary while making
an action or drawing and then show again the previous objects hidden when finishing.
Let's suppose to hide these objects in red color. Click on
Copy Objects to New Layer
then Enter key, following your command line, to create a new layer. In the new window
digit the name of your new layer and click on
If you check, you will have two copies of the same object, one belonging to the
older layer, and the one to the newer one.
If you don't need the first object, just delete it to keep the object
into the new layer only.
You can see this effect also in the third space in the section layers, next to the coloured
small square. By clicking on it, you can further check the full list of layers you
actually have, and the
In case you want to add new objects to your newest layer, just select them and click on
the slot before. Then choose in the list the layer with the name of the newest one.
In this case you won't have any extra copy, since you are just moving an object
between two layers.
You can see in such list four different icons. The last one simply says the main color
of the layer, which is called
The first icon is used to hide or show all the objects related to the layer considered.
Hiding all objects of a layer will make them invisible, so you can't edit, move, or
see them either. Last important one is the
belonging to such layer, so that you can see them, but you can't actually edit or move
them in any way. Use Lock or the first icon depending on what you actually need
to see and to do.
Well, that's all you need to make your 2D design projects!
