Faouweb Posted June 8, 2015 Posted June 8, 2015 Hi, I want to use the quick calculator to draw a circle on a line in X units from an END point using the VEC variable, I used for example 5*vec1(end,end) but the circle is 5 units from the origin (and parallel the line ) and not from the end point as you can see in the image capture: What is the correct method? Thank you Quote
lrm Posted June 10, 2015 Posted June 10, 2015 Try the following for the expression: 5*vec1(end,end)+vec([0,0,0],end) This will prompt you to click 3 endpoints. The first two will be used to define a unit vector in the direction from 1 to 2, and the third endpoint will be used to note the point from where the vector with a magnitude of 5 will be measured from. Vec1 defines a unit vector whereas vec defines a position vector between two points. ~Lee Quote
BIGAL Posted June 10, 2015 Posted June 10, 2015 1st Have a look at this http://www.cadtutor.net/forum/showthread.php?92643-Enter-a-Donut-at-two-ends-of-a-line.-Please-Help!-Appreciated!&highlight=DONUT may be usefull 2nd Also maybe a macro that uses the UCS to set direction draw a circle on end then move and drag with mouse ortho n then just type 5. 3rd use a lisp pick end all done Quote
