Bend an extrusion
Bend an extrusion
(OP)
Hi all,
I have a some parts, long I-beams cross drilled, but the beam itself is on a radius (150metres).
To make this the flat beam is put up on a mill and drilled, then run through a press to get the radius.
However, if I sweep a section, then put the holes through at the spacing they mill them to, they are out, equally working out the individual angles for each hole has and will take an long time.
The question, is there a way of extruding the I-beam, putting the holes in, then bending it to the radius (following the manufacturing route)? I have always thought you model something how you would make it, but!
Thanks
Mac

design the straight rail add holes then use global shaping or Global Shaping by Function. give it a try

The radius goes through the web centre line in the vertical plane.
It would be much the same issue as the railway rails.

In other words, is it this shape (we'll call it 'A'):
Or this ('B'):

Edit -> Surface -> Global Shaping by Surface...
...function to 'deform' the original extruded 'beam'. And despite the fact that this is ostensibly an 'Surface' editing function, there is an option to use it with Solid bodies, which is how I used it.
Anyway, take a look and see is this is what you were looking for. Note that ALL aspects of this beam in terms of size and bending radius are fully parametric (simply go to the Part Navigator and expand the 'User Expressions' folder). Note that the Beam Length and Bend Radius are in Meters while all of the other Dimensions are in Millimeters.
