Surface Mastery Part 7 - Blending Multiple Surfaces with 3D Splines, Lofts and Patches | How To

In this video we are going to carry on with the Ferrari 308 Fender and look at building the wheel opening. This, along with many surfacing tasks, comes with decisions and challenges. For this part we need to decide where and how to split up surfaces, build 3d curves and which surface tool to use.
We will explore 2 different methods to split up and build out a fender flare using Patch with Fillets and using Lofts. We will also go back and build the original fender a bit quicker using 3d splines and find the pros and cons of working with 3d sketches.
Which is best?
Here is the dataset to follow along. a360.co/3BLNCwu

Appreciate you showing both methods. I like the tendency control using projected 2D sketches but do not appreciate the added work needed to get it to work. I believe practice is the only way to get more proficient at this. Thanks for the insight like always.

Thanks for sharing! And yeah in other CAD systems you can have 2 different 2d sketches and build a 3d curve off of them. For whatever reason Inventor and Fusion want you to make a 3rd sketch which complicates things. At least with Inventor the 3rd sketch consumes the first 2 so it keeps things a little cleaner. Once Fusion has a bit better 3d sketch control the 3d approach will be much easier. Right now its still kind of tricky with splines.

Random question, if you've made a circular hole in a surface and screwed around with it so much that it's no longer perfectly circular, is there an easy way fix it? Not that I would have done something like that :D

[@LearnEverythingAboutDesign]

LOL. me either ;) well unless the surface was a plane I don't know that it would ever stay a true circle. There are times when patching the hole and cutting a new one are the best option.... maybe thats where you are at?

[@brianfuller7241]

​@@LearnEverythingAboutDesign That might work. But to answer your question, I think the point I'm at is "start from scratch", for about the 6th time already. Form workflows are HARD. You make it look too easy!!

@@brianfuller7241 what are you trying to model?

[@brianfuller7241]

@@LearnEverythingAboutDesign a headlight shroud for the first gen Miata. My original approach was based loosely on your MR2 tutorial. I finished one iteration, but the 3d printed part had some edge weakness issues that I couldn't solve. I'm starting from scratch making it a one-piece shroud and lid and hoping to make better decisions along the way this time. The design kinda got out of hand and was just brutal to work with.

@@brianfuller7241 Very cool. are you going away from the stock NA round headlight and doing something lower? If you want to join the discord server send an email to [e-mail] there is a growing group on there and a place to ask questions and share designs. if you want.
