coin-op Posted October 18, 2006 Share Posted October 18, 2006 I'm trying to teach myself ACAD2004 and am working through some practice sheets and I've hit a problem that I just cannot solve. I want to draw an arc (that according to the drawing I am working from is part of a circle with a 50mm radius) between a circle and the corner point of a line. I've attached a .jpg and my .dwg if someone can advise me how to do it I'd be grateful. I suspect that it is not entirely straight forward and a little ACAD voodoo will be involved. Thanks handle & spanner.dwg Quote Link to comment Share on other sites More sharing options...
yedan Posted October 18, 2006 Share Posted October 18, 2006 not sure there is a command for this but you can work it out using your radius information, like this. 1, draw a circle of radius 50mm with its centre on the end of the 16mm straight line near the middle of the handle 2, draw a circle of radius 60mm with its centre on the centre of the radius 10mm bulb at the end of the handle, (60mm is your connecting arc radius + the radius of your bulb) 3, where the 60mm circle intersects the 50mm draw a third circle with a radius of 50mm you should now be able to trim the last circle you have drawn to achieve your goal.

Groutie Posted October 21, 2006 Share Posted October 21, 2006 Any one got a use for this tool?? Quote Link to comment Share on other sites More sharing options...
coin-op Posted October 21, 2006 Author Share Posted October 21, 2006 Groutie, I don't think it has a use! It's just an exercise sheet I was given for drawing practice as I'm an AutoCad newbie. I like your 3D drawing. Waay beyond my ability at the moment though but hopefully I'll be there soon. Quote Link to comment Share on other sites More sharing options...

smorales02 Posted November 25, 2008 Share Posted November 25, 2008 Look into the Tan Tan radius option under the circle command...See if that helps Quote Link to comment Share on other sites More sharing options...

Attila The Gel Posted November 26, 2008 Share Posted November 26, 2008 Look into the Tan Tan radius option under the circle command...See if that helps I tried this in the first drawing but it didnt help Quote Link to comment Share on other sites More sharing options...
stevsmith Posted November 26, 2008 Share Posted November 26, 2008 try this. Ive used steps in cad rad roblem.dwg Quote Link to comment Share on other sites More sharing options...
Attila The Gel Posted November 26, 2008 Share Posted November 26, 2008 try this.Ive used steps in cad Strange When i tried this it didn't work??? I'll try it later on, There is a slight difference between the 60-50mm cirlce solution and the arc start end radius. Quote Link to comment Share on other sites More sharing options...
CadKid Posted November 27, 2008 Share Posted November 27, 2008 lol what a funkie lookin tool....not sure how useful it would be Quote Link to comment Share on other sites More sharing options...
mugshot Posted November 27, 2008 Share Posted November 27, 2008 1. make a line bet. the circle and and the rectangle to join your arc. 2. make a perpendicular line with a length of 50mm 3. draw a circle with Ø50mm 4 draw a line end-end to the drawn upside -down "t" 5 move the circle intersecting the diagonal line, eithe of the diagonal lines. 6 trim.
