I'm in the midst of a 3d modeling project, to create a driver center for a PRR locomotive. I normally use Autocad for my cad work, including in 3d, because I've used it for a long time and am fairly fluent with it. However, I'm also in the midst of trying to learn Solidworks, so I'm trying to mimic my Autocad efforts in Solidworks with this driver center.
As noted in the attached video, I can handle quite a bit of the tasks in Solidworks, without incident. But I do have an issue when creating the wheel spokes. The problem I have is that the data I have on hand to create and loft profiles, results in too-short spokes which fully intersect neither the crank pin boss or the outer rim of the driver. So I need a way to lengthen them, without altering the overall characteristics of the orignal loft, meaning things like the rate of taper.
The solution is simple in Autocad, but maybe not so much in Solidworks. I've not been able to find a reference that tells me if I can apply my Autocad method to a Solidworks solution. Or if there even is a Solidworks solution. So I'm hoping somebody here can point me in the right direction.
It's all explained in the video, I believe. Much simpler than trying to describe the situation with words only. First though I have some images of the drawing. You can see the spoke profiles in the top right corner. Their positions relative to the wheel center and rim are called out as Section A-A and Section B-B, along the horizontal spoke to the right of the crank pin boss.
And here's the video:
Hopefully someone can enlighten me.
Thanks,
Jim
