AutoCad :: Connect Points To Draw Involute For Gear Tooth
Nov 25, 2012
I am drawing a gear and now i need to connect points to draw involute for a gear tooth: [URL] ...
Points are numbered. I'm trying to draw with a spline, but i don't know where to put last point of a spline to draw an exact involute - like for example - if i would draw like this and press enter - i would get this spline: [URL] ...
But if i would move cursor in a different direction and then press enter - i would still get almost identical spline, but still, not the same: [URL] ...
So how do i draw an accurate involute? Maybe i should draw one more point and then stop drawing spline?

The attached file shows a gear tooth profile that I need to sweep along the lines shown. The problem is those lines are not all parallel to the UCS The tooth profile is a region.
Is there a workaround to make this happen? I used to do this all the time in 2008.
I couldn't attach the file 'cause it wss too big so I saved it as a PDF but now I can't attach that because it is not a DWG
How do I attach a PDF?

I have generated a gear set using inventor. Now I would like to 3d print the gears. I have uesd the export tooth shape to get the true tooth profile. now I am attempting to use the coil feature to generate the helical tooth. The problem im running into is in the coil tool I can only give it a Revolution and height dimension. The hight is the width of the gear, but I am having a problem converting the helix angle to the "Revolution" perameter. I have read other posts and they say that it is Helix angle / 360. I have tried that and then compared it to the original gear generated by inventor and it is not even close. I need to do this on in internal gear and match it to an external gear.

We have some details of Internal Involute Spline profile,.Now it has to be made by EDM Wire cutting,.I need the nomenclature of Internal Involute,.
I browsed in Internet and I found some details, but all of them explaining Major Dia, Minor Dia, Spline pitch, Circular Pitch, tooth Thickness, etc,.But I need how to draw the involute,Please see the attachment "How to draw this" Automated Programs are secondary, reasons,.
1. I am a Mechanical Engineer, I should know how to Draw it, also I am addict in Mechanical Engineering, so I like to know it,.
2. Installing Software's are prohibited in our organization, it can not be done without Higher officials permission, also it will take time to finish this process,.

I'm not able to get the right gear rotation in a planetary gear drive that I'm working on.
If I make the ring gear stationary and rotate the sun gear, the planetary gear engages and rotates around the ring gear
but in the opposite direction of what it should be turning. The planet to sun gear engagement rotates backwards regardless of what I do to the rotation constraint that I've applied.
If I make the ring gear free to rotate, and the planet gear stationary, the gear train rotates properly.
I've attached a mock up of the plant gear system to share and show what I'm dealing with.

Using autocad 2008. I cant draw a rectangle using 2 points. I don't need a specific size just want to put a box around text. I used to pick a point and then pick point 2 to draw rectangle. On this computer when I use rectangle it ask for length and then width. Is there a system variable that won't let me put in p1 and drag to p2 to make a rectangle?

I have to put some trusts between two beam. It sounds easy but i'm unable to handle the divide and round off commands in the lisp. See attachement also.
To draw my trust between the 2 beams, what I normally do, is that I manually take the distance between the two points say it's 10 000 and wrote it down. Then I divide it by my max gap, say 1200, it is the max space between trust.
10 000/1200 = 8.333333 that's the result of how much trust and space between them that i'll need, 8 trusts, 9 spaces between the 2 beams. (That is what I'm unable to do in the lisp, tell it to round off 8.333 to 9 and use 9 for divide command)
What I manually do at this point to draw these trust is that I must create a temporarly line between the 2 beams, perpendicularly to these and divide it by 9.
It gives me 8 cross (or point) to draw my trusts. All this is long to do manually because I have many bay in building and I have to redo this operation for every the bay.
So, what I would like the lisp to ask is:
Specify distance between two beams (Between where and where) :
Specify the lenght of the trust :
Specify max gap: I would like to answer a number here, say like 1200 max
(The lisp should draw the lines on the current layer, color and linetype of the current layer and not draw a line at the beginning and at the end because that's where my Beams are. I hoped you understand, see attachement.
Should also have something that handle a ESCAPE hit or cancel, something like this:
(defun trap1 (errmsg) (command "_.undo" "_end") ; undo end (setvar "osmode" oldsnap) ; restore variables (setvar "cmdecho" 1) ; enable cmdecho (setq *error* temperr) ; restore old error handler (prompt "

I'm trying to change a routine i just wrote that draws 3d pipes. I wanted to make it so that when a user selects the beginning point and ending point of the pipe, the LISP changes the ucs to that vector, draws the circle at the beginning point and extrudes it to the second point.
It actually works great except when the ucs changes, so do my user points because of teh origin change. Is there a better way I might get this to do what I wnat it to?
(setq ip (getpoint "
Pick First Point:"))(setq ep (getpoint "
Pick Second Point:"))(command ".ucs" "za" ip ep)(setvar "osmode" 0)(command ".circle" ip "d" od)(command ".extrude" (entlast) "" (distance ip ep))(command ".ucs" "w")(setvar "osmode" oldsnap))
