Design Control Arm With AutoCAD

Hi design engineer, welcome back with me Tutorial of CAD that will show you about design with AutoCAD, Autodesk Inventor, Catia, SolidWorks. But this time I will give you autoCAD tutorial, and the title is how to design control arm with autocad. This part is one of part of machine that you may know it. I think this part is so simple to design with autocad or other CAD software, especially if you use special design software for 3D (3 Dimension). If you are accustomed to drawing with Autocad, I think it will also be easy to make this design.

Design Control Arm With AutoCAD – AutoCAD Tutorial

First, Open AutoCad Software. And then click FILE menu – click New to make new window.

Click Line menu or you can type L in command column and then click enter. Click in drawing area or you can type 0,0 in command and enter to get central coordinate. After that type @100,0 to make line 100 mm in X coordinate. AutoCAD Tutorial

 Next step is making circle at beginning of the line and end of the line. Make circle in the beginning with radius 30 mm and 15 mm. Click Circle menu or you can type C and then enter, click beginning of line and type R enter and type again 30 then enter. Click circle again or type C and enter, click the beginning of line for center of circle, type R enter and type 15 enter. If you are correct to follow my instruction, your draw will be like below :AutoCAD Tutorial

 Next, make circle again with radius 50 mm and 40 mm. Type C and enter, click the end of line to make it center of the circle, and type 50 enter. Make circle again, type C enter or click Circle menu and click the end of line to be center of circle, type 40 enter. check below :

– Continue to next step, make Line again with length 125 mm and 51 degrees, click Line menu or type L enter. Click the end of first line and then type @125<51 Enter. Check below :

Make circle again in the end of angle line with radius 25mm and radius 10mm. Click Circle menu in the bar or type C enter, type R enter and 25 enter. And then make circle with 10mm also.

 And now please make arc line to join first big circle with radius 40 mm. To make it easier, you can make a circle first with a radius 40 mm. check below:

 Move the circle that you just made until you join between 2 big circle. If you are confused, check picture below. Click Move menu or type M enter, select object or select the circle that you want to move.

AutoCAD Tutorial After that cut or trim the circle until like below. Click Trim menu or type TR enter type ALL enter 2 times and choose the line that you want to trim, after you trim the line click enter.

 After you mirror the arc line. Click Mirror menu or type MI enter, select object or select line that you want to mirror then enter. Then click first point and second point that will be a mirror (select beginning of axis line and the end of axis line). After that you will see choices, it is N / Y. N = NO, it means no erase the line / part of mirror. Y = Yes, it means you will erase the line or part of mirror. And you choose and then enter.Tutorial of CAD

 Next, we will make arc line again, it’s same like above. Make circle again with radius 60 mm, and move until you can join the Big circle. Click C enter and then click the center of circle and type 60 enter. Check below :

 Then click Move or type M enter, select the circle enter, click area drawing around big circle and move the circle until the circle touch the big circle.

 Click Trim menu or type TR enter, type ALL enter 2 times then select the line that you want to trim or cut. Check below to know the result:

– Click 2D wireframe and then top view. Make line again to help us make circle radius 22 mm and 25 mm. Click Line menu or type L enter, click center of big circle, type @20,0 enter.

Design Control Arm With AutoCAD

 Then make circle with radius 22 mm and 25 mm. Click Circle menu or type C enter click end point of the line that we have just made, type 22 enter. Then make circle 25 mm. Then erase center line that connect center of circle (100 mm, 125 mm).

Design Control Arm With AutoCAD

 Make Line again that connect quadrant circle radius 22 mm with quadrant circle 40 mm. (if your quadrant not active, you can active first. Right click in OSNAP below drawing area, then click setting and then check quadrant).

 Make circle radius 5 mm to make arc in angle. Click circle menu or type C enter, click the end of center line or beginning center line (so that it’s same axis with the arc line), and type 5 enter.

Design Control Arm With AutoCAD

 Move the small circle radius 5 mm until like picture below. Click Move menu or type M enter, click area drawing and move the circle like below: ( if you are difficult to move the circle, non active the OSNAP and POLAR first)

Design Control Arm With AutoCAD

 Click trim menu or type TR enter type all enter 2 times, and trim the angle line and the circle, so that it becomes as shown below:

  1. […] Mastering one of design software is a must for current design engineers. It’s even better to master more than one of software design. Because in general the company will find employees as engineers who master software design such as Autocad, Mechanical desktop, Autodesk Inventor, Solidworks, Catia, Pro-e and others. Therefore, if we have aspirations to become an engineer, we must master one of these software. Here I will try to show how to design control arm with Solidworks, which I have previously tried to design control arm with Autocad. […]
