What is the direction to recreate a part like this?

[Anonymous]

Im new to CAM and CAD and ive been learning a lot over the last few weeks following tutorials and the like but they are usually making very basic objects. I'm trying to replicate a interior door panel for my S10 that is not being manufactured anymore so I can 3D print it.

Ive tried the "Solid" and "Form" workflows and both didnt feel like the correct way to proceed. I have no idea how to create these type of curves in sketches and then how to get them to join together. Ive tried a completely defined sketch of the front and back without a canvas and a calibrated canvas. Its the V shape of the piece and that front curve or swoop thats really getting me stuck. 

Ive attached a few photos of the piece. Its all most a "V" shape from the rear profile.

** Also, would "Mirror" be the correct way to get this model to be for the Driver Side since this is the Passenger Side?

Thank you so much for the time, and any information!FrontRear

Top view and right side of the line, would be where I would start.

Then the top left face.  Because you can measure it, set up on a flat table and take height measurements.

Might help.....

Hi,

Your project can be described as very demanding.
Even if you were to give tips on solid or surface tools, this would hardly lead to the goal without sufficient experience with them.
So: practice, practice ...

hello @Anonymous,

Hello ----- I don't see any possibility to renew your part from work in fusion.

Why?

the important parts are missing and these are the clip hooks. without this you will not be able to clip the part.

but there is hope if you want to repair the existing part.

get a filament pen and after you have placed the part well, melt the missing clip parts from behind.
your surface of the part would not be so nice and stable anyway.

I hope to be able to help     --- greetings mango

Can you File>Export your *.f3d file of your best attempt to your local drive and then Attach it here to a Reply?

This is exactly how I went about it. I can recreate the piece with measurements from my digital calipers on a flat plane with no problem. Its only when I get to how to twist it to follow the curve and twist that I run into problems of how to proceed. Thanks for the reply, it lets me know my thought process isn't completely off. 🙂

I have the measurements of the tabs that are broken off. The front rightmost tab is still intact but that is a great solution and I will keep that in mind when I go to put this piece back on the door panel!

I will rework this now and attach it here.

Here's where I'm at right now. I left filets and the completion of the rear plastic clips out at this stage but wanted to show my general approach to adding them in. My "front" sketch was getting a "over defined/driven constraints" warning so I had to start another sketch? That's something else to look into... haha. 

Anyways, thanks for taking a look!

I'm guessing you don't have access to a 3D scanner so have you looked into photogrammetry for this at all? I've never actually got around to trying it but intend to have a go at it one day.

Hello @Anonymous --- may I give you a quick tip?

first draw the two areas in the size I have marked them for you.

print out these parts and you will see that you must not touch the clips because they will break immediately.

you have drawn a width of the clips of 1.7 mm.

that is far too little in the direction of the layer, with an extruder of 0.4 mm that is just 4 lines. the cross-section and the direction of the layers are without any force.

when you've tried this you'll wake up knowing it can't work.

for the strength -- you will need for the clips you have to put this part on edge, which in turn brings other problems.

Before you go to far - I recommend that you investigate techniques for fully defining sketches.

This should be mastered before proceeding to a design of this complexity.

I am using a .4mm nozzle and can print .2 layer height with the current settings I have dialed in on this printer. I will add another tab and cut the model down to print these parts to see how strong they are. That's a good heads up!

I am aware of the importance of fully defining a sketch. This version I included did not have a fully constrained sketch. Also, this versions sketches share a "Front" and "Back" pieces which I imagine would get me into trouble. Maybe not though since I can always just project the geometry to where its needed?

Iv'e been looking at all kinds of tutorials trying to learn as much as I can on different modeling techniques. 

A idea I'm stuck on is fully defining the side panels (thin pieces on the side) on a origin and extruding them into each other with a join command?  

Iv'e also been experimenting with 'Thin Extrude" so I can extrude along a spline and not a full profile.

side profile sketch not used?  should it be at the right edge.

If so what is the profile at the left edge....

fillet the ledge looks about right....

Loft the two end profiles, and go from there.

Might help...
