I have a problem, and i would appreciate some help. Here is the
1. I have to model a 150x25 channel rolled to 2000id, toes out. The way
i did this was to insert the appropriate sketch from the structural
steel toolbox and then, with the help of a centre line, used the
revolve boss command to complete.
2. Now i have put holes to put on the inside face. I cannot think of an
easy way of doing this. Maybe I have drawn the channel wrong in the
first instance. I would prefer to be able to flatten the channel, but
using the revolved boss command has made this impossible.
Any help would be much appreciated!
I would suggest creating a long straight channel of the proper length,
adding all of your holes, and finally bending the piece with the Flex
Alternatively, you can create the the revolved part, create the sketch for
your holes, and perform a Wrap operation to cut the holes. (This was
suggested by P. in a previous posting.)
Depending upon your goal, you might consider simply cutting circular holes
in the revolved part. Although this won't accurately represent the finished
part (assuming the holes are to be drilled prior to bending), it would be
convenient for dimensioning in a drawing.
You mentioned flattening the channel after creating it with a revolve. You
would have to make the channel a sheetmetal part in order to take such an
approach. Such an approach is possible, but would require you to change the
channel to be a sheetmetal part with constant wall thickness, etc. I assume
you will be happier with an approach that would avoid this restriction and
allow you to accurately represent the structural steel profile.
Wrap has the advantage of providing dimensions from the sketch in the

2 other possibilities-
A)draw a revolved hole somewhere using a new radial plane and use the
circular pattern tool and your axis of rotation to generate your other
holes- suppress any unwanted instances
B)use the hole wizard to pick 3d points on the surface
make a flat web and insert a bend, flatten bend ,cut in your holes,
rebend and revolve or sweep some flanges onto it, add fillets. this
will allow you to produce a flattened view of the flange back with
holes shown in a dwg
Well, I didn't think of it either till he asked and I did some testing.
I've been trying to find a way to get holes on curved surfaces that I
can dimension on a print. Finding the answer to his question helped a
bit in that direction.
John Eric Volt> Good point. I hadn't thought of that.
