is it possible to design this shape in Fusion ?

[kamalwindows11]

I'm trying to make bicycle project to practice fusion 360 designing and the only part left to design it is the 

 rear derailleur , I'm trying to design the one called shimano 105 R7000D 11-speed rear derailleur and 

I can't figure how this part can be designed in fusion , can it be designed in form or solid workspace 

And how , can you give some hints, please ?

[laughingcreek]

yes, that can be designed in fusion.  if you can post some better reference pics i'm sure you'll get some hints on getting started.

You have already asked and received help on this question.  Why are you starting a new post?

[kamalwindows11]

Thank you for replying , this is a different part from the previous one , also no one answers my previous question and I hope someone will help me with this part 

[kamalwindows11]

here are some other pics of the part ,also I have given the name of it if you want to search more:

by "good" reference pics, I mean ortho graphic views from multiple vantage points.

are the axis of these 3 holes aligned in the same direction?

do you have one of these you can take apart and get better pics of?  actually holding something in your hand can help immensely in being able to understand it's geometry.

side note-you can put your pic you clipboard and then ctrl-v (paste) right into a post so folks don't have to open it up

Thanks for your effort , unfortunately,I don't have the part , these are all the manuals associated with this part from shimano official website

Yes, that is possible. However, for a beginner who yet has to get his head around sketch basics as evidenced in your other thread, this is way to advanced of a project.

@jhackney1972 the OP is not talking about the derailleur cage plate, but about the main body and linkage. These are very complex shapes!

Thank you so much, can this shape be designed in form or solid workspace , what do you recommend me to learn in order to be able to design these complicated shapes ?

Hybrid modeling (solid geometry and surfaces) might work, but you'll have to get your head around surface based workflows. The sweep and loft tools are your friends for these shapes. The first step is to understand Splines and NURBS and I usually link to the Autodesk Alias Theory Builders 

Alias is a high end surfacing application and unaffordable for mere mortals, but the concepts explained in these documents translate across applications.

The basic idea here is that you create surfaces and even solid bodies with the loft/sweep tools. The essential building blocks of these shapes are (trimmed) NURBS surfaces. Curves are the basic building blocks for these surfaces.

Use curves with the least amount of control points ( control point splines or also called CV splines). If you use fit point splines the same principle applies. Use the least amount of points you can get away with and then work with the tangent handles. Always check the curvature comb of your sketch curves  and also the curvature of your edges.

Thank you so much for helping.
