foro per mandrinatura

Good morning to all,
I am entering the use of solidworks independently before doing a specific course (just to spend some time), after years of drawing with autocad 3d and to practice I am taking inspiration from paper drawings that I have in the office.
one that I would like to model is that of a tube plate for a heat exchanger which has spindle tubes; in the various tests that I have done, I can pierce the plate as required by the step (I make the hole sketch according to the step, extruded with cutting, I make a linear series, and more or less we are), what I can not do is create the rigging inside the hole for the spindle.
I tried to create the negative to make a size with revolution; I create it correctly on the plane, but then I can't move it to the center of the hole to make the revolution, I hope I could explain myself.
Thank you for the time you give me.

You put two images with the final result, but not the solid one. indicate which bevel you should do would help.
there is the bevelous function.
there is the guided drilling command that includes flared holes. if there is no measure you need you can use the nearest one and then change the sketch within the function.
the wizarding function includes two sketches: the insertion point and the cutting sketch revolution.
if you have to make a set of identical holes I recommend using the guided drilling instead of the extruded cut.
Before embarking on the autonomous modeling, do the internal tutorials to gain dimensity with the commands and the logic of the parametric cad.
insert the version of the program on the profile to have advices; when you have modeling problems always attach the file so that you can analyze the problem, you can use common references and you can possibly correct 360°

thanks to the advice, actually the first approach went well knowing the 3d of autocad (with simple things), but going a little more on the professional you are in front of a wall

forget autocad3d. forget autocad.
solidworks is a parametric cad where by changing an entity you can generate changes to cascade on multiple details and related designs.
in autocad a line is simply a line, the gates and make another equal and nothing happens; in solidworks a line is a well defined entity and erase it and make it another means losing references and creating errors.
to understand it you just make a simple try: draws a picture, at his side draws another painting by listing it from a edge of the first, back into the sketch of the first picture, gates and remakes the line to which the share of the second picture is attached. you will see that you will get a mistake

I think you're right. Thanks again.
