BOOLEAN INTERSECTION ONE POINT

Hello,
I am trying to do some models where have the intersection in one point only (to surfaces of cylinders) in a part of the structure but also a plane surface, the problem I have is I want this model for doing modelisations after, for the moment what I have done is make it in a way that the cylinders are a little bit smaller to be able to intersect the parts. but this brings me some problems in the modelization after,
is it possible to do it with another tool in Onshape?
for an example of what I am talking about (because is a little bit difficult to explain, sorry English is not my main language...)

the part 1 and 2 are the ones that the boolean doesn't arrive to intersect
the part 3 is only the exterior of the part where the boolean doesn't present any problem obviously.
and the part 4 is the same as the part 1 and 2 but with a slightly smaller diameter of the cylinder, it is the only way I found to do de boolean be able to generate something.
but as I want to use the CAD model to make a mesh and use it in another software I would like to arrive in do it with the reals sizes.
(also a small note I need a tool that works when there is a lot of points intersections like if in the part 1 and part 2 are more than 1 cylinder.... the document I shared is only one to make the example more clear)

If you are creating a mesh for FEA, wouldn't that create a singularity?
