Every workpiece created in AutoCAD has its own properties (Properties) in many topics, such as Layers. We can use the Layers Properties command to check the details as shown in Figure 1
Or if wanting to know other Properties, it’s not difficult to do by Select workpiece and command LIST (LI), program will display report as shown in Figure 2
In drawing it is possible for us to create new pieces. But would like to use the properties of existing work such as sample work, I have drawn a section (section) showing the details of the stairs and inserting a Hatch to show the material. But I have already created 1 piece that has the Hatch pattern that I want. For convenience, I choose to use the Matchprop command to copy this property from the prototype as shown in Figure 3.
Figure 4 shows the location of the Matchprop command.
Then the command will have the following steps:
1. Select a prototype (Select source object), click to select the desired Hatch pattern and then Enter as shown in Figure 5.
2.Then select the destination workpiece (that you want to change properties), notice the cursor has changed to a paint brush as shown in Figure 6.
3.After Enter, found that the Hatch destination workpiece will be changed to the same as the source workpiece as shown in Figure 7.
The Matchprop command can be used to change the properties of every object, called copy or clone. Come on, that’s all. It’s a very useful command for work.
The Slice command is used to slice 3D Solids into sections along a specified plane. It is a command that allows us to perform complex tasks and show job details.
Let’s see how this Slice command works. Start by creating Solids as shown in Figure 1, then select the Slice tool in the Solids Editing tool group as shown.
When an order is selected the program will allow us to select the desired piece of work (must be 3D Solids only to continue working), select the work as in Figure 2 (Select objects to slice).
After that, there will be a choice that Specify start point of slicing plane or [Planar object/Surface/Zaxis/View/XY/YZ/ZX/3points] <3points>: as shown in Figure 3
The choice I suggest in this chapter is 3points (or 3 coordinates). I put points 1, 2 and 3 in position. As in the picture, the simple way to think is Let’s say we have a knife. Let’s cut this piece apart into two pieces. I can divide it in many directions. depending on the plane of the blade in this case, I will cut along a plane parallel to the workpiece length. And cut from top to bottom, so points 1 and 2 are vertical cutting planes, while points 2 and 3 are longitudinal cutting planes.
After Enter, the program will ask whether specify a point on desired side or [keep Both sides]: Means we click to select the part of the work to be kept (delete the other part) or to keep both. If we select Both (both) will get the work as shown in Figure 4
You can see that the work piece is divided into pieces 1 and 2, but still in the same position. can be separated by using the move command as shown in Figure 5
With work that is Solids can be used further In addition, slices can be done in multiple planes. I try to make slice plane or Slice plane to increase understanding, create Solids and try to use slice command.
(Multiple)Point or Point is a command in the Draw group.
I think that there are quite a few people who are curious about this command. What is it used for? If you use point to create workpieces, it may not be suitable. because the work would come out as a line drawn by a point And no one does that. So what is the benefit of this command? Point here refers to the reference point itself. Creating a reference point is what we do when we want to divide the workpiece into parts, for example, with one straight line. Want to divide into 3 equal parts.
The dividing point is to use the point as a reference point. Therefore, Point can be used as a reference. Must have a face that is more noticeable than normal spots We have to change the point style or Point Style to change from the normal way. The command used to change Point Style is DDPTYPE. Found that there are many styles to choose from.
It found that there are many styles to choose from. Click on the Point Style box that you want to use.
Now let’s draw a horizontal straight line. any length Then select the Divide command as shown.
Object to divide selects a straight line. Then enter the value Number of segments as 4 (meaning divided into 4 parts).
The result is as shown in the figure: the line is divided into 4 sections, referenced by points in the selected style as shown.
Therefore, the Point command is the command to create a reference point. Using in conjunction with other commands, Point Style can be set by using the DDPTYPE command.
UCS stands for User Co-ordinate System, meaning user coordinate system (defined by the user).
This term has both meaning and command. UCS is related to WCS (World Co-ordinate System) normal coordinates (AutoCAD uses the word world as normal). If you observe the screen in every work, there will be a sign showing WCS at the bottom left corner of the screen called the WCS Icon as shown.
In the normal state, this icon indicates the 3 axes (axis) in working, namely X, Y and Z, which are arranged at right angles to each other according to Right Hand Rule 1 In the 3D view, the Z axis (blue) is perpendicular to the X, Y axes, meaning that the working plane is the plane that is parallel to XY only as shown.
Or the area shown in red If we want to work in the green or blue plane, we can’t. Because it is a plane that is not parallel to the XY plane (XY plane) because the program requires us to create work in a plane parallel to the XY plane only, so from the figure to create tasks on the green plane The XY plane must be rotated parallel to this green plane before any work can be created on this plane.
To rotate the working plane, use the command UCS to rotate the coordinates in the direction that we (User) want to adjust from the normal position when starting to work. Adjust coordinates from normal (world) to user (user) coordinates for 3D creation.
UCS commands are commands with several options and descriptions. Today I would like to use a convenient and comprehensive method. That is using the alternative UCS / 3-point tool as shown.
Once the order has been selected, set the 3 coordinates as shown in the figure.
By starting at point 1, the origin point, then going to point 2, the end of the X axis, and point 3, the end of the y axis. Then the working plane will change as shown.
Notice that the UCS Icon has an XY plane parallel to the desired (green) area. If a work piece is created, it will be on this plane. Try modeling and rotating the 3-point UCS to change the working plane in different ways to gain insight.
If you have a problem, ask any time in the comments.
AutoCAD is a vector program that has both dimensions and directions.
So, it’s important to know the direction. To drag or write individual shapes The Axis system therefore plays a role in helping users to know which direction they are currently working in. AutoCAD starts with 2D (2D) work. The term 2D means seeing distances only on two sides: width and length.
The symbol (WCS: World Co-Ordinating System) is displayed in the lower left corner of the program as the two axes are X and Y as shown in Fig 1.
But in reality, we live in a 3D world (3D), which requires another axis. Representing the height, that is the Z axis. But when we look at it in 2D, the Z axis will be directed towards us.
Theoretically, the Z axis is invisible. If we want to see the Z axis, we have to change the angle of view from 2D to 3D, so the Z axis will be revealed.
