I can't post files due to NDA. I am backwards engineering a part and have two surfaces that are drafted at different angles and different depths. I need to create a third surface (blue face below) that drafts between the two of them. Any ideas?
There might be simpler steps to this, but you can look at my attached example to see how I got it to work.
How far have you got so far? How do the two faces you have intersect? Are you trying to make this face by removing material, or adding material? Can you post another screenshot or two to show what you have already and clarify the problem you are having?
Here you go Erik
Thanks for your help and I'm new at this. Is there an attachment?
At the bottom of my previous post you should see a link to "draft JS.SLDPRT.zip". You should be able to click on it to download or right click and save-as.
Thanks for making up the model. I was thinking that the edge indicated in the pic' below was supposed to be perpendicular to the top edge. If that is the case then the corner fill may, or may not, be planar, depending on the exact dimensions of Bryans part. If the edge is supposed to be perpendicular, and the geometry of the rest of Bryan's part is not just right, then he will most likely need to use a surface like I did in the second pic. If that is the case Bryan may need to play around to get the exact shape he needs, I just used really basic surfacing to fill the corner, Bryan may want to use more sophisticated methods, boundary surfaces or such to get a more suitable shape for his purpose.
I rolled back your model and put the surface corner fill in as another configuration. Also by using the Direction of Extrusion option on your cut and extrude I was able to eliminate a couple of features using that method.
Erik, at first I thought that edge was supposed to be perpendicular too, but when I realized that would make the surface non-planar then I decided to ignore that constraint. I don't know whether or not Bryan actually needs it perpendicular.
Also good thinking with the extrude direction change, that makes it much simpler.
IMO, you both are freaking awesome. Turns out that it does not need to be perpendicular, but it does lean the opposite direction (below). The benefit to Jamil's method is we don't do a lot of surfacing here, so most of our CAD are not familiar with it. I've tried to get them to learn it, but it's black magic to them. They are scared of Sheetmetal too, even though we bend and form electrical contacts.
If you are ever in Southern Indiana, let me know and I'll buy you a beer.
When you have a choice definitely stick with the easy way. I would certainly use cuts and extrudes over surfaces in this case.
Also, I encourage you to push your guys to pick up the basics of surfaces, and sheetmetal. The swoopy curvey surfacing stuff (check out Mark Biasotti's work) can get pretty magical pretty fast, but the basic stuff is easy enough for a guy like me, and comes in very handy on occasions. Sheetmetal is not that hard either, again, you can do some pretty wild stuff, but the basics are not that difficult to figure out. It's the sort of stuff where once they plunge in and figure it out, they'll wonder what they were afraid of, and why they waited so long.
I agree that they should have a basic familiarity with it, but there is really just no use for it in this industry. We make electrical connectors. The products are all squared off with radii and chamfers. Surfacing just does not play a large role in our field.
The old guard here won't try SM because they had a bad experience with it when it first came out. I've tried to get it into the line up, but, old dogs and new tricks...
And an alternative to Jamil's
You should be able to use the draft feature with the "part line" option to draft that face. Some faces are not draft able- if they are algorithmic in nature, you can not draft them. Alternately if Draft with part line does not work, you can try using the Move Face>Rotate feature.
