Reshape tool for a 3D object

[Biscontin]

Hi everybody, 

 

Is there a way to use the Reshape Tool to reduce the length of a 3D solid by its vertexes?

Using the rectangular marquee mode and dragging the vertex to a certain point... similar to what I do with the 2D shape in the video.

 

See video.

 

Thanks.

Switch to a Top / Plan View and use the Selection Tool (not the Reshape tool).

Or double-click on the Extruded object which will take you into the object and then you can use the Reshape Tool on the original 2D object.

I think that will also scale the Fillet radius - in stretch direction only, to a kind of Ellipse Arch.

AFAIK same distortion would happen, instead of Fillet, with a simple rectangular edge cutout.

 

 

And if it would be a simple generic Solid, there is no chance to go into 2D Edit Mode to make use of better 2D Tools.

 

V1 :

Extract bottom Face, (convert to something else if needed), Edit in 2D, Extrude

V2 :

PushPull move Side Face (Fillet may disappear), redo Fillet

At first I didn’t think it did stretch the fillet, but I think you’re right — it probably did stretch the Filleted corner so that it is no longer a radius. Ignore my first suggestion to use the Selection tool.

You’re also correct that if it is a generic solid, double-clicking on it won’t help you — but following the OP’s example workflow of extruding a 2D shape, the best option is the second one I mentioned: double-clicking the Extrude and editing the original 2D shape with the Reshape tool.

What if I have a more complex solid, like a C-shape, like this in the video. Is it possible to "stretch" it and shorten it maintaining the fillet?

I realise this probably isn't a particularly 'cool' way of doing it but what I do a lot of is look at the object in an orthogonal view, use the Split Tool to slice it in half, move half of the object one way or the other depending on whether seeking to enlarge or shrink it, then Push/Pull to enlarge one half if that's the intent + Add Solids to make it a single object again, or just Add Solids if the intent was to make it smaller. Sounds long-winded + amateurish I know but it's actually very quick + easy + I do it all the time. In fact although the Split Tool is in the Basic/2D tool set I think I probably use it most for 3D modelling.

I guess this would work for this type of shapes, not the ideal workflow but an acceptable compromise.

Even though, for more complex shapes with many vertexes to stretch, it would be impossible.

What about converting to Mesh then reshaping with Selection Tool in Transform Mode...?

 

 

 

This isn't something I ever do + I don't know much about Meshes so no doubt there are drawbacks to converting it. I can see it's facetted the fillets.

@Biscontin  Can I ask, what exactly is your endgame.  You seem to be looking for a solution to a specific problem, but if we saw the whole picture there might  be a better solution or methodology.

 

Granted, there might not, but worth a try on slow Sundays.

Correct, here is an example, see videos. I need to "stretch" all the vertex of that solid 20mm to the left.

As I would do with the Reshape Tool on a 2D.

In that specific case, do as per previous suggestions and edit the 2d shape(s) that the extrude is made from. To make things easier to edit retrospectively it's worth keeping this in mind. So in this case, it might be better to add/compose the rectangles together into one polygon *before* extruding (rather than adding the solids together after extruding).

 

NB that if desired, you can further streamline this by selecting all the rectangles, then doing the extrude command. This will extrude them into one solid, but double clicking it will get you straight back to the group of individual rectangles (which may or may not be more convenient for editing, than a single 2d polygon).

Hello,

New in Update 4:

Check out the ability to scale objects with the 3D dragger:

 

 

 

 

 

 

 

 

Cheers,

It's a useful new feature but doesn't actually help in this particular case, where the OP wants to be able to select a bunch of vertices and move them only - rather than stretching the whole object.
