Hello Everyone, I am new to Fusion 360. I am have been able to import the attached step file. The only issue is I am not able to thicken the panels. I was wondering if anyone knows how to do this please? Thank you in advanced for your time and support.

Please share the model by exporting it to a .f3d file and attaching it to your next post.

Thank you @TrippyLighting; please find it attached in the f3d format.

The two objects in hat file are already solid bodies (BRep) . Those cannot be further thickened. 

Can you explain what you want to achieve ?

What is your experience level with Fusion 360 and other CAD software?

OOPS!  I got my posts crossed.

Hi,

Bring the two bodies (out of nirvana) to a position that allows them to be viewed.

@TrippyLighting thank you for looking into the f3d model. I worked with SolidEdge for nearly two decades and I have just started using Fusion 360. I am finding Fusion 360 much easier than SolidEdge as well as its free for hobbies like myself. But both software are not able to solve my dilemma which is how to thicken this front material?

 

 

The model you see is from a real train which I have scaled down by a ratio of 1:48. When I do this; the panels become so thin that when I 3D print it; they simply collapse as shown by the picture below:

The rest of the train is ok because I have modelled it from scratch. I would like to use the original front of the train (after scaling it down) in order to create some form of realism for the students who will use it to learn to program it (using Arduino and IoT). Any ideas on how to thicken the material or if there is a way to trace the shape and recreate it somehow please?

Hi @g-andresen, thank you for looking into the model. I am not able to follow what you have done. Could you kindly enlighten me please?

Hi,

I have arranged the two bodies in such a way that they can be displayed together and the section profiles can be shown in a section analysis.

@oharran6X46N 

Lets take a step back.

 

1. There are two solid bodies in the design (see screenshot) For your purposes I assume that you only need the outer one. I would also assume that the rectangular cutout is also not needed. Can you confirm both questions?

2. In the file you attached I would assume that represent the original, unscaled form. The thickness between the 2 selected surfaces is 18 mm. If you scale that object down by factor  48 you'll end up with a distance of 0.375mm.

 

For reasons that should be obvious , a simple thickening of the object is not going to accomplish much. How thick do you want to make this ?

Hello @TrippyLighting , please find my answers below:

 

1. There are two solid bodies in the design (see screenshot) For your purposes I assume that you only need the outer one. I would also assume that the rectangular cutout is also not needed. Can you confirm both questions?

 

Answer: You are right. I only need the outer layer. The rectangular cut-out is not needed.

 

2. In the file you attached I would assume that represent the original, unscaled form. The thickness between the 2 selected surfaces is 18 mm. If you scale that object down by factor  48 you'll end up with a distance of 0.375mm. For reasons that should be obvious , a simple thickening of the object is not going to accomplish much. How thick do you want to make this ?

 

Answer: You are right; the file I attached is unscaled. The 3D printer needs at least 2mm thickness across the wall. I prefer to have a 5 mm thickness across the panel to ensure that the part is strong enough (which is 240mm in the unscaled model). Thank you once again for your time and support.

At the moment I am not sure what I would advise you to do. This looks like a surface modeling project to me.

My first attempt would be to detach the front and rear surfaces, move the rea surface by the desired amount to get the desired thickness and then loft between the two outer contours.

 

However, the results of that approach might not satisfy your requirements and then things can get more time consuming.

 

As I've mentioned already, thickening cannot work here for several reasons.

@TrippyLighting  that is a good idea. I will give it a go this weekend. The aim is simply to thicken the material on the inside; it doesn't matter how it looks from the inside as long as the exterior still looks the same. InshAllah I will keep you posted on how I got along with it this weekend. Thank you once again for the idea.
