Multiple angles and planes

[ShaneRussell]

I am having a very hard time trying to create this model.  It basically a triangular block with lots of compound angles and intersecting triangles.  Sculpt doesn't do the angular cuts I'm looking for and Model won't let me grab an edge or vertex and force it into position.

I might be able to do it what a couple of dozen sketches.

Here's a front view:

Any workflow or technique advise would be greatly appreciated.

do the surfaces need to stay flat (planer), or can they be potato chipped some what?  if that's ok you could draw a network of 3d lines and patch a surface between them

[ShaneRussell]

I would prefer them to be planer.  Would that mean I need to create a construction plane for each "facet"?

The Extrude function works great for turning a square into a cube.  What if you want to turn a square into a pyramid?  Must you use Loft to a point?

[laughingcreek]

in DM mode you can do some interesting things with directly rotating and moving faces, while keeping them planer  I think creating a construction plane for every face might be unwieldy.  but I suspect there are a handful of other technics you could employ to achieve what your trying to do.

Can you sketch out or other wise give a better idea of what your tying to do?  I have to admit I don't quite under stand the sketch you posted.

While this can be done in polygon modeling I personally would not attempt to do that with the lacking modeling tools in Fusion 360's T-spline environment.

This  would look like a surface model to me with many splits.

if you attach the model with that sketch I can demonstrate what I mean. This looks like the layout for the cockpit of some sort of helicopter or space ship.

Looks like a robot face to me. 

Either way you can attack this with a ton of methods including T-Splines.

DM mode offers more of what your after with this thou, provided your not looking for it to be parametrics.

You can also do this with solid modeling by extruding shapes then cutting away the angles your after.

[ShaneRussell]

It is a robot face.  I mainly have been doing the extrude shapes and cut away, but there are so many compound angles and planes it's just so frustrating.

What exactly is DM mode?  I didn't consider t-splines because everything is so chiselled and angular.  I've tried Patch but can't get the edges setup in 3D space, if that makes sense.

@ShaneRussell

DM is Direct Modeling (aka) Modeling without history. T-Splines can be used you just have to learn how they work. I will try to put a couple of videos together when I get some time as I model robots all the time. Currently working on training material to model a Gundam Astray Red Frame now.

I'm also a fan of Gundam.  I would love to see these tutorials.

Sorry for the dumb questions, I've had Fusion 360 for only a few months.

@ShaneRussell

I want to give you fair warning now...understand that you will not be creating planar faces unless you use what I am about to show you to make guide sketches to do ref plane layouts for proper geometry. I show T-Splines first....Then I show the same thing with surfaces. This is just the basics to get you started and by no means an end to all the problems your about to face. 

That being said here is one way to do what you want to do.

[ShaneRussell]

Thank you!  That's exactly what I was looking for.  My front sketch and side sketch will be used as reference and your method should allow me to tweak the final shapes.

Too bad I'm at work and have to wait until Sunday to work on this.  The anticipation is killing me.

Glad I could help. Once you get started if you run into problems just ask.

Here was the thread for the Beam Rifle I made for the Red Frame last year.

Extruding bits and pieces and using draft to set the angle seems to be doing the trick.  The order of operations has to be perfect or everything falls apart.

It's rough, but it's a good start.  Thanks again for your help.
