AutoCAD: Array-Polar

Arranging workpieces into categories is done with the Array command (Modify command group) as shown in Figure 1.

Figure 1

The Array command has two options:

1. Rectangular > Row and line arrangement

2. Polar > circular arrangement

For now, we’ll talk about the Polar Array, experimenting with circular arrangements. Start by creating Circle (Circle) up 2 pieces as shown in Figure 3.

Figure 3

When selecting the Array command, there will be options as shown in Figure 4.

Figure 4

Follow these steps:

1. Select the Polar Array first.

2. Click on the Select Objects heading, then return to select the object you want to arrange.

3. Set the center point in the arrangement (Center point), select the Center of the large circle.

4. Come to the topic Total number of items to enter the desired amount.

5. Set the angle to fill in the arrangement (Angle to fill), in this case put 360 means that the arrangement is within 360 degrees or equal to 1 around the circle.

When enter, you will get output as shown in Figure 5.

Figure 5

It is a command that is used very often. There is also an Array / Rectangular option. and will be presented later.

AutoCAD: Match Properties -Adjust work piece properties according to the prototype.

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

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

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 3

Figure 4 shows the location of the Matchprop command.

Figure 4

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.

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.

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.

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.
