27-5. Example5 Tutorial Finished 2Nd Drawings

For this fifth AutoCAD example, I volition endeavour to exhibit how to depict a 2D drawing using the next commands LINE, CIRCLE, FILLET, OFFSET, TRIM, MIRROR, Tan-Tan-Radius.

The rootage way to depict 2D drawings inwards AutoCAD

To empathise it immediately, I exhibit an illustration of how I depict a drawing. Each private has his ain organization as well as the way of drawing, as well as this drawing tin rank notice hold upwardly drawn inwards several ways. So, exercise non stick to these steps strictly. Draw the drawing every bit you lot recall it is easiest to do. (Of course, utilization all the possible commands you lot know as well as the sequence of steps you lot want.)

The finished drawing looks similar this below. Notice the circle numbers as well as lines on the drawing, which I fix to tending you lot follow the tutorial as well as steps.

I exhibit an illustration of how I depict a drawing 27-5. Example5 Tutorial Finished 2D Drawings

So let's become started amongst the next settings. I defined color lines for all my Layers. Of course, also this, you lot should also exercise your ain Dimensioning style for Plot on newspaper as well as visibility of the elements of Dienomenon style). I bring laid the color lines for dimensioning at value 210.

First, what you lot involve to exercise earlier you lot start reading this tutorial, written report the dimensions on the drawing. I unremarkably start drawing, thence I brand auxiliary lines that volition serve me for drawing, which tin rank notice hold upwardly afterwards deleted or hidden. I bring a specific color for them.

Step 1.

First, nosotros volition depict an auxiliary horizontal business (I've drawn a crimson line) that volition serve every bit the starting indicate for drawing a circle. Its length volition hold upwardly 75 units. At the ends of the auxiliary line, I volition exercise all iv circles amongst radius.

Radius for the circle 1 = 6
Radius for the circle 2 = 13
Radius for the circle three = xviii (diameter is 36)
Radius for the circle 4 = 25 (diameter is 50)

Command: _circle
Specify pump indicate for circle or [3P/2P/Ttr (tan tan radius)]:
Specify radius of circle or [Diameter] <8.0000>:
>>Enter novel value for ORTHOMODE <0>:
Resuming CIRCLE command.
Specify radius of circle or [Diameter] <8.0000>: 6

Command:
Command: _circle
Specify pump indicate for circle or [3P/2P/Ttr (tan tan radius)]:
Specify radius of circle or [Diameter] <6.0000>: 13

Command:
Command: _circle
Specify pump indicate for circle or [3P/2P/Ttr (tan tan radius)]:
Specify radius of circle or [Diameter] <13.0000>: 18

Command:
Command: _circle
Specify pump indicate for circle or [3P/2P/Ttr (tan tan radius)]:
Specify radius of circle or [Diameter] <18.0000>: 25

Step 2.

Now, nosotros volition connect the outer circles amongst the line. First permit us turon 'On' a niche for the TANGENT circle. Right-click on the OSNAP push inwards the Status Toolbar as well as thence on the Settings tab. The "Drafting Settings" window opens, where you lot tin rank notice plough on the Tangent => click on the OK button.

Now let's depict the line. The OSNAP mode push is turned on. Default Layer is a thick business (yellow color). Click on the LINE button. Now seat the mouse pointer to the circle position out 2 as well as click when nosotros appear to Tangent magnetic point, thence seat the mouse pointer to the circle position out 4 as well as when a magnetic indicate for the tangent click the mouse, as well as thence press Escape to complete drawing the line. Let's repeat the same for the instant business (bottom).

Step 3.

We volition at nowadays duplicate the previously drawn outline amongst a spacing of vii units. For that nosotros volition utilization the OFFSET command.
Click on the overstep business to choose it as well as thence click on the OFFSET ascendency push (now the mouse pointer is transformed into a minor square). In the Command Prompt line, move into the value of 7, thence deed the mouse pointer to ane of the sides of the selected business (in this instance below the line) as well as thence click the left mouse button. We nonetheless bring the mouse pointer a piffling square, which agency nosotros tin rank notice snuff it on to choose it further. Select the second, bottom business as well as thence seat the mouse pointer over it as well as click LTM (left mouse button). Now press ESCAPE to complete the Offset command.

Command: _offset
Current settings: Erase source=No Layer=Source OFFSETGAPTYPE=0
Specify offset distance or [Through/Erase/Layer] <Through>: 7

Specify indicate on side to offset or [Exit/Multiple/Undo] <Exit>:[ click on ane of the sides of the line]
Select object to offset or [Exit/Undo] <Exit>:[ continued selection of the side yesteryear side line]

Notice inwards the moving-picture exhibit inwards a higher house that nosotros could depict the same novel lines every bit the exterior lines but I wanted to exhibit how the OFFSET command is used.

Step 4.

Now nosotros bring all the necessary lines as well as to continue, nosotros bring internal lines circular off the outer circles. We volition exercise this amongst the ascendency DRAW => CIRCLE => Tan-Tan-Radius from the File menu.

Now nosotros indicate the mouse pointer to the upper inner business until the magnetic indicate for the Tangent is shown, the left mouse click.

Then seat the mouse pointer on circle position out 4, as well as when the magnetic indicate for Tangent appears, click LTM (left mouse).

Now nosotros involve the Command Prompt Line to move into the value for the radius. Write value 8.

Command: _circle
Specify pump indicate for circle or [3P/2P/Ttr (tan tan radius)]: _ttr [choice of option]
Specify indicate on object for rootage tangent of circle: [click on the line]
Specify indicate on object for instant tangent of circle: [click on the circle]
Specify radius of circle <25.0000>: 8 [value of radius]

Now nosotros bring this province of affairs every bit inwards the moving-picture exhibit below.

Step 5.

Now nosotros involve to cutting off the business to become the await of our drawing. For that nosotros volition utilization the TRIM command. Click on the TRIM ascendency as well as thence choose the circle, thence press ENTER to consummate the selection as well as thence click on the purpose of the business that nosotros desire to cutting (delete).

Now let's cutting off a purpose of the circle that's the surplus. Again click on the TRIM command, choose the upper inner business as well as thence choose the circle, press Enter as well as thence click on the bottom of the circle.

Also, brand a circle on the left as well as thence TRIM. Now nosotros bring this province of affairs every bit below. This is why nosotros bring drawn the upper purpose of the inner business as well as the arches. In the same way nosotros tin rank notice depict the lower purpose of the drawing (internal lines as well as 2 arcs).

The instant way to depict 2D drawings from this tutorial example

Here I volition explicate around other way of drawing lines as well as circles every bit good every bit trimming inwards pace 5. Imagine that nosotros did non run offset on the lower outer business thence they could utilization the MIRROR command to mirror the upper inner business as well as the arches.

How to exercise it?
Select the upper inner business as well as arches at its ends. It looks similar this inwards the moving-picture exhibit below.

Now click on the MIRROR ascendency as well as thence click on the left endpoint of the crimson line, thence click on the correct Endpoint crimson line, as well as thence press ENTER.
That is the halt of drawing AutoCAD drawings.
