Cutting a Cylinder with a line (intersect)

Hi everyone,

i am trying to change an existing script that calculates a quite complex geometry based on a FREECAD hook in python to use the cadquery package.

The biggest difference i saw was the information saved in the variables.
E.g. when i try to get information of my object i allways have to use functions and can't just use obj.BoundBox.

**My Problem:**
I am trying to intersect a line with a cylinder and get the start and end point of the intersection-line aswell as its length.
In my FREECAD python script version it was programmed as follows:

```
total_length=0
length=[]
for i in range(0,len(struts)):
line=Part.makeLine((struts[i][0],struts[i][1],struts[i][2]),(struts[i][3], struts[i][4], struts[i][5])) #create a FreeCAD Line
cut_line = cylinder.common(line) #cut with the cylinder to remove excess

if len(cut_line.Vertexes)==2:
# this saves the start and end point of the line which was cut by the cylinder
struts[i] = [cut_line.Vertexes[0].Point[0],cut_line.Vertexes[0].Point[1],cut_line.Vertexes[0].Point[2],cut_line.Vertexes[1].Point[0],cut_line.Vertexes[1].Point[1],cut_line.Vertexes[1].Point[2]]

length.append(cut_line.Length) #create vector with length of the lines
total_length+=cut_line.Length #add all these lengths
del line
del cut_line
```

I cannot find any functions to achieve the same with cadquery.

Thanks for your help!

Best regards,

Mischa
