Help drawing in AutoCAD

Anonymous — Mon, 11 Feb 2019 08:33:29 GMT

Can anyone explain to me how I would make this drawing in AutoCAD and where to start. What I start at 0 0 and then moved from coordinate to coordinate using the Cartesian coordinate system based on student one so on and so forth. Does anybody know exactly what the drawing is asking

Hi,

are you asking because you don't understand the job to do or you don't know how to draw this?

What about asking your teacher who gave you that instructions?

Were you assigned to be Student 1 or another number?

Let's assume Student 1. The starting point is 0,0. moving up and to the right Point 1 is X=0.50 (C dim), Y=2.00 (B dim) or Point 1 coordinates are 0.5,2.00, Point 2 is X=1.00 (D dim), Y=1.50 (A dim) or Point 2 coordinates are 1.0,1.50, and so on for Student 1 dimensions.

So start the line command, type 0,0 <enter> .5,2 <enter> 1,1.5 <enter> ... Finally use the coordinates given at the bottom of the image and enter those one at a time and hit enter (you would still be in the line command).

Probably easiest to first write the dims from the table at each letter on the drawing, then taking the X dim first and then Y write the X,Y coordinates at each point.

This is pretty simple. Literally if you initiate the line command you are halfway there. It prompts you for the information you have. All you have to do from there is enter your coordinate data.

type in: LINE [the command line asks for the first point, if you dont have the command line up press ctrl+9]

type in: 0,0 [your first point]

type in: X,Y [substituting for X,Y your numbers assigned to you]

type in: X,Y [repeat the process]

type in: X,Y

etc etc.....

if your line on your drawing is going down your Y value should be negative and if your line is going from right to left your x value will be negative.

If you are struggling with this i would definitely talk to your instructor as @Alfred.NESWADBA mentioned. This is rudimentary stuff.

Torchmate is a CAD/CAM

Why not just draw it with Torchmate and you don't have to know how to setup a drawing with Atocad?

The problem with this response is, the student was not asking for help with Torchmate , and Torchmate is not what his professor is teaching.

Well the drawing can be made in CAD and then brought into torchmate and then converted into G-Code. I'm just wondering where to start because when I tried drawing and CAD I used the coordinates it gave at the bottom and the drawing came out looking totally different although it would be different no matter what because the sizes are different. My specific student would be students at 3 I know how to pull the measurements from the top just not the bottom if you could help me with that would greatly appreciate it I would be up as a picture. You also the angles I do not know how to calculate them if you noticed the black marks in the drawing how do I calculate those angles for student 3l

Hi,

@Anonymous

>> I'm just wondering where to start

Look to the sketch, you'll see the point 0,0,0 and that is your base point too

>> because when I tried drawing and CAD I used the coordinates it

>> gave at the bottom and the drawing came out looking totally different

Please upload your dwg-file so we can see what is different.

>> My specific student would be students at 3

You should not expect to get a finished file here, because that would avoid that you learn your job. Even if it's hard at the beginning, getting a finished dwg-file makes your troubles even worse in the future with more complex drawings.

@Bob_Zurunkle

>> and Torchmate is not what his professor is teaching

Please look to the second image that was uploaded from OP, it contains: "... load the program into Torchmate and ...."

Hi,

Please excuse me if I missed anyone's instruction regarding absolute vs relative coordinates.

AutoCAD typically fires up with relative coordinates active via the Dynamic Input drawing tool. Relative input will yeild a far diferent result in constructing your profile than absolute.

The assignment appears to be requiring absolute coordinates as I judge it.

All suggestions I have read will work great for absolute coordinates you just need to turn off Dynamic Input to enter the coordinates successfully. Type DYNMODE and enter 0 or off for its setting.

There are other wasy to get absolute coordinates active for use but this is the quickest in my opinion. If you plan on using AutoCAD and learning it more be sure to turn DYNMODE back on and learn a bit about CAD coordinate usage >here<.

Much luck

because my instructor wants us to be able to import vector or dxf files into torchmate.

i'm asking how to draw this for student 3 . Every time I try to enter the coordinates 0,0) (2.5,0) ect the coordinates at the bottom my lines look nothing like the drawing.. if i can get the bottom drawin i can pull the lengths of the a b c ... ect ling and draw them by intercecting lines .. also i do not know the angle of the peaks

Hi,

>> Every time I try to enter the coordinates 0,0) (2.5,0) ect the coordinates

>> at the bottom my lines look nothing like the drawing

Please make sure dynamic input is turned off, so you can be sure the coordinates you enter are absolute coordinates,

Then start command

_LINE<ENTER>

0,0<ENTER>

2.5,0<ENTER>

....better?

Again, if that does not work then please upload the dwg-file you created, uploading the same JPG-file every time does not make too much sense.

Here try this:

use command PLINE and when it ask you for for starting point, copy and paste the coordinates in from the .txt file attached

Re: Help drawing in AutoCAD

GrantsPirate — Mon, 11 Feb 2019 23:05:47 GMT

You don't need any angles and you don't need to draw lines to find intersections. The coordinates of every point is given to you, some explicitly along the bottom, the others from the table. Dims A and B are the Y coordinates depending on the point in question. Dims C, D, E, F are the X coordinates depending on the point in question.

Point 1 = 1,2.5

Point 2 = 1.5,2

so on.
