shrinking a part while keeping the overall dimensions?

[Anonymous]

Hi, I'm making a positive and negative version of a stamp, though I need to change the gaps between the parts. Scaling doesn't work because the positions between the elements change. I need to push/pull each part by the side-faces. THOUGH: I can't find a way to easily select all faces in a certain axis nor can't I use the selection-tool to select hidden faces..?

In this example I want to make the lines of the dolphin bigger, so I have to push/pull the faces.... is there any way to get this done?
I couldn't find a way to select all connected faces.... looks like somebody forgot an important tool, or? Please help... I'm getting crazy 😛

Hi @Anonymous,

Before we can help you, you need to take care of all the Yellows and Reds in the Timeline!!!

Cheers / Ben

Well, sadly the software doesn't suggest how. And from what I see here the errors are not related to my prob right now.

But anyway: even if I start with a plain new object without errors I can't seem to find a way to do it. So, could you just tell

me how I shrink the parts without moving the overall the position? In Blender it is easy peasy to shrink an object from it's outer shell dimensions, but

that does not help me here. I can't believe Autodesk forgot that function.

The warnings are telling you that something is broken and you cannot just ignore them. It's usually happen, when you delete a reference body/sketch/plan.
I can also see, that you have used the move command excessively, which is also not a good practice.

Please make a screencast and explain exactly what are you trying to do. It will also be a good idea to attach the file as well.

What about using a parameter to pilot the width of the gap ? I gave it a quick try (my dolphin is a bit sick, sorry).

You are right - there is no great way to do this in Fusion today, assuming I understand your request.  Press/Pull, which allows you to do a face offset, is the only real tool available.  And, selecting the right set of faces is tricky.  I've found that using Selection Sets is one way to do this.

Here is a screencast showing one way to do this using selection sets:

Hmmm...when working with sub-d models and I believe this is also possible with T-Splines in Fusion 360 you can select an entire face loop.

That same algorithm to detect a face loop should work here as well. Then offsetting that face loop would work very easily.

Did you select just the edges? How? I found the window for user-parameters, though I don't see a way to tell the program to set a width for the selection... I feel dumb....

Thank you for the help, I did ran into an error so I trashed the earlier file and started from the beginning (using a SVG, extruding the logo and I make a negative extrusion to cut out the logo from a cuboid. Then I select all faces, save that selection and try to push/pull it and end up with  "The operation could not create a valid result" and tells me to try changing the input geometry.  

Please excuse my naivitiy... I come from Photoshop CC and Blender... so I'm a bit lost with that right now...

Since I'm a F360-noob... how can I do that? 🙂
