objects: select the object to be arrayed. (The small rectangle.)
6. Select objects: select more objects or <Enter> to stop.
7. Specify Path Curve: select the Path. (The angled line.)
|
|
The Path can be a line, polyline, spline helix, arc circle or ellipse. |
The Array Creation Tab appears and the array defaults to 9 items.
8. Make any alterations and press <Enter> to display.
9. If correct select Close Array.
Note: If you want to change the number of items on the path, you will need to select the Measure drop-down arrow on the Properties Panel, then select Divide. You can then change the number of items in the Items Panel.
The Break command allows you to break an object at a single point (Break at Point) or between two points (Break). I think of it as breaking a single line segment into two segments or taking a bite out of an object.
Method 1: Break at a Single Point
How to break one line into two separate objects with no visible space in between.
1. Select the Break at Point command by using:
Ribbon = Home Tab / Modify Panel /
2. _BREAK Select objects: select the object to break (P1).
3. Specify first break point: select break location (P2) accurately.
Note: The single line is now 2 lines but there is no gap in between the 2 lines. For example, a 2 inch long line would become two 1 inch lines butted together.
Method 2: Break between 2 points (Take a bite out of an object) Use this method if the location of the Break is not important.
1. Select the Break command by using one of the following:
Ribbon = Home Tab / Modify Panel / or Keyboard = BR <Enter>
2. _BREAK Select object: pick the first break location (P1).
3. Specify second break point or [First point]: select break location (P2) accurately.
Note:
A. Circles break counterclockwise. (CCW)
B. Circles can’t be broken with “1 point”. You must use 2 points.
The following method is the same as method 2 above; however, use this method if the location of the break is very specific.
1. Select the Break command.
2. _BREAK Select objects: select the object to break (P1) anywhere on the object.
3. Specify second break point or [First point]: type F <Enter>.
4. Specify first break point: select the first break location (P2) accurately.
5. Specify second break point: select the second break location (P3) accurately.
The Chamfer command allows you to create a chamfered corner on two lines. There are 2 methods: Distance (below) and Angle (next page).
Distance method
Distance method requires input of a distance for each side of the corner.
1. Select the Chamfer command using one of the following:
Ribbon = Home Tab / Modify Panel / or Keyboard = CHA <Enter>
Command: _CHAMFER
(TRIM mode) Current chamfer Dist1 = 0.000, Dist2 = 0.000
Select first line or [Undo/Polyline/Distance/Angle/Trim/mEthod/Multiple]: select “D” <Enter>.
Specify first chamfer distance <0.000>: type the distance for first side <Enter>.
Specify second chamfer distance <0.000>: type the distance for second side <Enter>.
2. Now chamfer the object.
Select first line or [Undo/Polyline/Distance/Angle/Trim/mEthod/Multiple]: select the (First side) to be chamfered (distance 1).
Select second line or shift-select to apply corner or [Distance/Angle/Method]: select the (Second side) to be chamfered (distance 2).
Note: When you place the cursor on the second side, AutoCAD displays the chamfer and allows you to change the Distances before it is actually drawn. If you choose to change the Distance, select the Distance option, enter new distance values then select the 2nd side.
Angle method
Angle method requires input for the length of the line and an angle.
1. Select the Chamfer command
Command: _CHAMFER
(TRIM mode) Current chamfer Dist1 = 1.000, Dist2 = 1.000
Select first line or [Undo/Polyline/Distance/Angle/Trim/method/Multiple]: type A <Enter>.
Specify chamfer length on the first line <0.000>: type the chamfer length <Enter>.
Specify chamfer angle from the first line <0>: type the angle <Enter>.
2. Now chamfer the object
Select first line or [Undo/Polyline/Distance/Angle/Trim/mEthod/Multiple]: select the (First Line) to be chamfered. (The length side.)
Select second line or shift-select to apply corner: select the (second line) to be chamfered. (the Angle side.)
Options
Polyline: This option allows you to chamfer all intersections of a polyline in one operation. Such as all 4 corners of a rectangle.
Trim: This option controls whether the original
