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 ;)

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.
