 Topic: 2D Problem with circles in an equilateral tringle
Posted: 08.Mar.2014 at 21:29 |
Hi, its my first post here, i use AutoCAD2010. Below is the link of pic of the drawing i m talking about. I can create this drawing by. 1. making 1 circle of bottom row 10 radius. 2. copy that to the right 3 times 3. make another circle with ttr of above row 4. copy that to right 2 times 5. repeating same steps 2nd row 6. and top circle . 7. then making boundary line with xline (horizontal) and using line command + tan + bject snap tracking.
8. Trim and scale the whole figure with reference of given dimension.
I have 2 questions here.
1) Is there any simpler way to make this drawing?
2) How can i build this drawing if i first make the triangle and then circle? |

An easier way to create the drawing would take another program. Have you ever heard of "nesting" software?

The nesting program would be an AutoCAD add-on.
Another option would be a custom lisp routine.

Lisp is a programming language that is support in AutoCAD as well as .NET and VBA.
Some AutoCAD users create their own lisp programs to do repetitive tasks or to help them do a complex task more easily.

I tried your little exercise and despite doing it differently it still took me eight steps.
However, if the triangle was drawn first then it could be done in seven steps.
