Faouweb Posted June 8, 2015 Share 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 Link to comment Share on other sites More sharing options...
lrm Posted June 10, 2015 Share 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 Link to comment Share on other sites More sharing options...
BIGAL Posted June 10, 2015 Share 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 Link to comment Share on other sites More sharing options...
