In the Drafting Settings dialog box, Polar Tracking tab:

clip_image006

Select 15 from the Increment Angle list.

Under Polar Angle Measurement, click Absolute.

 

On the Snap and Grid tab:

clip_image008

Click PolarSnap.

Enter 1 in the Polar Distance field.

 

On the Object Snap tab:

Make sure Endpoint and Node are selected.

Click OK.

 

To draw the line using polar tracking:

clip_image012

Activate the Line tool.

1. Specify the line's start point from the point object, using the Node object snap override.

2. Drag the cursor to the right until the polar tracking tooltip reads 25.00 < 0 degrees. Click the point.

 

Position the cursor so that the polar angle tooltip reads 15.00 < 45. Click the point.

Position the cursor so that the polar angle tooltip reads 25.00 <0. Click the point.

clip_image016

 

Position the cursor so that the polar angle tooltip reads 15.00 <315. Click the point.

clip_image018

 

Position the cursor so that the polar angle tooltip reads 25.00 <0. Click the point.

clip_image020

 

Move the cursor upwards until the polar tracking cursor reads 70.00 < 90. Click the point.

clip_image022

 

Repeat these steps to draw the top half of the object which mirrors the bottom half, changing the Polar angle accordingly. Your final endpoint should be at the original start point.

Ten Commandments of a GOOD AutoCAD Operator

Image
Ten Ways to Do No Harm Taken from AutoCAD 2008 for Dummies by David Byrnes Be Precise I remind you that using precision techniques such as snap, object snaps, and typed coordinates is a fundamental part of good CAD practice. Don’t try to use AutoCAD like an illustration program, in which you eyeball locations and distances. Use one of the many AutoCAD precision techniques every time you specify a point or distance. Control Properties by Layer AutoCAD gives you two different ways of controlling object properties such as color, linetype, and lineweight: by layer and by object. Unless you have a really good reason to assign properties by object — such as instructions from your company’s CAD manager or the client for whom you’re creating the drawing — use the by-layer method: Assign colors, linetypes, and lineweights to layers, and let objects inherit their properties from the layer on which they reside. Don’t assign explicit color, linetype, or lineweight to objects. Know Your Dra...

How to Create a Custom Paper Size Using DWF6 e Plot.pc3 in AutoCAD

Image
After you have completed a drawing, you can store it on the computer storage device such as hard drive or flash drive. However, to get its hard copy, you should plot or print the drawing on a sheet of paper using a plotter or printer. This tutorial we will learn how to configure the layout or creating a custom paper size without having trouble in a multiple printer installed in your system. Step 1 1. On AutoCAD, click the Layout1 Tab to switch from Model Space to Paper Space. Step 2 1. Right Click on the Layout1 Tab. 2. Select Page Setup Manager... Step 3 On the Page Setup Manager Dialog Click the Modify... button. Step 4 1. On the Plot dialog box, click on the drop-down list of Printer/Plotter Name to select a type of printer/plotter you need. 2. Choose DWF6 ePlot.pc3 as your printer. Step 5 Still on Plot dialog box do the following: 1. On Plot Scale, change inches to mm as unit. 2. Then choose 1:1 as scale. 3. Then click Properties button to display the Plotter Conf...

Entering Points in AutoCAD: DIRECT DISTANCE ENTRY

Image
You can draw a line by specifying the length of the line and its direction using D irect Distance Entry . The Direction is determined by the position of the cursor, and the length of the line is entered from the keyboard. If the ortho mode is on, you can draw lines along the X or Y axis by specifying the length of the line and positioning the cursor along the ortho. You can also use it with the other draw commands like the rectangle command. You can use Direct Distance Entry with polar tracking and SNAPANG (snap angle). For example if SNAPANG is 45-degree and ortho mode is off, you can draw a line at 45 or 135-degree direction by positioning the cursor and entering the distance from the keyboard. Similarly, if the polar tracking is on, you can position the cursor at the predefined angles and then enter the length of the line from the keyboard.
