HELP!_modelling an inlet tract within block...
(OP)
Hi, I am a newbie with Solidworks so bear with me....
I am trying to model a cylinder head with Solidworks 2001+.
My problem is that I cannot construct the inlet/exhaust tracts within the cylinder block (a simple cube).
I have tried to use the sweep function, but that only produces a solid. I want to extrude the shape within the block. The tracts are typical curved paths.
How could I model the tracts. It is very frustrating!

You will have to construct it using surfaces most likely, but it's been so long since most of us used SW01+, I'm sure our way of thinking will not work as well, since the version you are using is way limited then what we use today.

Converting old 2d paper drawings into solid models is also difficult because some cross sections that can be drawn in a 2d view do not connect in 3d, or SW will refuse the operation. Some curves are too sharp for a sweep or loft to follow. A lot of it was left to the pattern maker before, but SW does not have an icon for blend or file to fit.

EngJW: care to show me a pic of one of the drawings that you weren't able to use in a loft?
I got some really nice powerpoint presentations I found on the net showing exactly how to convince SW to produce the lofts the way you had intended. Check out the "Curvy stuff" tutorials.

I don't have anything that I can easily get to but typically it would be a round cross section lofted into a square or rectangular cross section. The round one would have an OD and ID (for the port wall)and the other section would have a wall of the same thickness.
This would generate an error message, something about using a single closed profile. I get around it by lofting a solid port for the outer wall and then a cut loft for the inside. It is a lot of extra work. It might just be my lack of knowledge or experience with this.
Thanks for the link. I will take a look at it.
