Multiple contours - Help request

AndrewVanis — Wed, 22 Jan 2025 23:52:26 GMT

Where is a good starting place to learn how to mimic these compound curves in the attached image and surfaces and the tools and processes to do so?

Objective is to create a nesting shape to cradle the neck if this wrench.

I am using parametric design for the various sizes so if a parametric approach was feasible it would be great

TIA

Thx, reattached, should be visible now

Flatbed scanner would be the simplest or a picture normal to the wrench. Insert the image as a canvas. Scale it. In a sketch trace the shape with arcs and straight lines (or a spline).

"In a sketch trace the shape with arcs and straight lines (or a spline)."

and then what? I'm used to using fillet or chamfer for such sharp edge modifications.

to clarify, I'm looking to modify (fillet?) the sharp green edges to conform to the radius shapes of the wrench - where it transitions to the bulkier bock shape towards the top.

Thanks

@AndrewVanis

I would use Combine-Cut Solid body from solid body

Split with Surface body.

How much experience do you have?

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

Done

Wrench holder = one with an extrusion, the one in the picture

Wrench 2025-1-21 = the re-do I am now working on. On Sketch2 the solid rectangle are the shank of the wrench, the construction line rectangles are the lower part of the head (where the flares terminate into the sharp edge rectangle)

@TheCADWhisperer

How much experience do you have?

Fairly beginner, maybe you can determine my level by attached file. With the numerous capabilities of Fusion I certainly am a fledgling

@etfrench

Thanks for the Video, yes heading in the right direction. The video shows a 2d cutout…. it would be the compound radii going up to the front that creates the front “hook” that has me most baffled. Attaching this old school envelope sketch to try and convey what I’m after..and then how to hopefully make the distances parametric like the other slots currently are.

Thanks for the replies and help.

@AndrewVanis

Edit Sketch2.

Click and drag this point horizontally to the left.

What do you observe?

Re: Multiple contours - Help request

AndrewVanis — Thu, 23 Jan 2025 20:07:38 GMT

gets wonky

That is not the current sketch/file. that is the prior "wrench holder" file I included for reference for the extrusion view

The current file "Wrench 2025-1-21" that I included is the file I'm working on. in this file, the respective point will not move sideways, only up/down.

Then what is it missing? (Hint: A vertical dimension.)

(The other file was missing a Vertical Constraint on the line.)

Do you have some pictures looking directly at the side and front faces of this tool?

Re: Multiple contours - Help request

AndrewVanis — Thu, 23 Jan 2025 20:37:44 GMT

On that part nothing is missing, it is the outside of the holder and unrelated to the wrench matching question.

I am asking about conforming the sharp edges (red in images below) to conform to the multi faceted radii of the wrench (purple highlighted) - imagine the wrench being hot and being pulled into that slot melting the plastic to conform to the radii

@AndrewVanis

Let's start by modeling the wrench end.

Re: Multiple contours - Help request

AndrewVanis — Thu, 23 Jan 2025 23:42:52 GMT

This is what I got so far. File attached.

Not sure how to do gusset/negative fillet

TrippyLighting — Fri, 24 Jan 2025 12:21:12 GMT

Here is how I would model this. Dimensions were chosen arbitrarily.

Model is attached.

The model in the video only uses one loft, but it needed additional explanation, hence the video.

@TrippyLighting That is beautiful! Thank you for the detailed video and thanks for attaching the file...I will review again in more detail, learn about loft, and may post Qs on that if needed. Definitely a great direction suggestion on which way to proceed. I'm excited about learning how to use this featur

A couple quick questions:

1) If the objective is to create the negative of this wrench shape in the holder. Is the preferred process still to model the wrench first or would it make sense to use this lift feature directly on the holder?

2) I notice on your example all the face arcs come down the same length. In fact the thin side arcs come down shorter than the wide side arcs. Any considerations for the loft function around that since it seems that it already needs some attention if how it interfaces with the arc edges?

Thank you again for your detailed and instructive post.

@AndrewVanis

1. You can use Combine-Subtract of the wrench from the Holder (or you might need to pattern or Sweep (Solid body) if I understand your problem description).

2. Can you edit @TrippyLighting example to get your Design Intent for the model?

@TheCADWhisperer

I'll work on those two items and report back.

Thanks for this. I have been working on this...could be a great solution!...There are several skills I have to practice to use this so thanks for the opportunity to learn these.

Would be nice to confirm before getting too far down this path....any reason I couldn't do the side way swipe demonstrated in your example first with the middle of the shank of the wrench to create the narrow slot and then swipe down to recess the head? The objective would be to have a couple of prongs?/some material to hold the head of the wrench from sliding forward when stored and then could be lifted up for removal.
