In my earlier articles, we have learned the Rectangular Array and Path Array Commands. In this article I will introduce you how to use Polar Array in AutoCAD 2013 using the Polar Array command. As depicted by the name this type of array is used to create multiple objects along some axis of rotation.
How to Use Polar Array Command:
Now in this article, we will see the final Array command and that how to use Polar Array command in AutoCAD 2013. This command as stated by the name will create arrays of the desired object by giving angles. See the following scenario.
We will select this command either by clicking on it or by writing AR on the command line. And select the object. After that we will write PO for Polar.
Select objects: Specify opposite corner: 3 found
Now select the Polar Array by writing PO on the command line.
Enter array type [Re----------------/POlar] <Rectangular>: po
Type = Polar Associative = Yes
Specify the axis of rotation.
Specify the center point of the array or [Base point/Axis of rotation]:
Specify number of items to create.
Select grip to edit array or [AS-------------/Items/------------------]<eXit>: i
Enter number of items in array or [Expression] <6>: 15
Select grip to edit array or [AS-----------------------------------------]<eXit>:
After completion of command our final image will be as shown below.
Now after covering the Array command I will try to elaborate remaining commands from the Modify toolbar. And the command that we have not covered so far are Scale, Stretch, Rotate, Trim, Extend, Break at Point, Break, Join, & Explode commands.
Using Scale Command:
The Scale command is used to enlarge or reduce the desired object. We can scale an object according to our requirements. Below is an object and in this practice we will enlarge this object by giving scale value 2. And after that we will reduce it by giving scale factor 0.5.
Note: In either case (that is enlarged or reduce) proportion of the object will remain unchanged. And scale factor will always be positive a nonzero number.
We will select the command either by clicking the icon from the Modify toolbar or by writing SC into the command line.
Select objects: —————————: 17 found
Specify base point:
Specify scale factor ——————–nce]: 2
After this command is complete our object will enlarges. And to reduce the object we will provide a scale factor equal to 0.5. The below image shows our object and two of its scaled versions.
In assembly drawing Scale command helps us to show a small object to a larger size, to better reveal its details and user readability.
Using Stretch Command:
As we can guess from the name, the Stretch command is used to elongate an object in a desired direction. Consider the object shown below. In this object circle to circle distance is 35 units. And we want this distance to be 45 units.
We will further proceed to the remaining part of this command into our next article.
