Can I easily adapt the model size

Good day,

From the warehouse, I found a model, I am interrested for. But it’s to large

I wonder, if I can easly resize with the Sclae tool without affecting the hole for the screw, etc.

I also would like to supress the 8 holes, but when I select it

I git a desaster :slight_smile:

Lastly, I would like to have the cover high as the bottom, and the bottom high as the cover (the cover need to be higher than the cover.

Starting form a model and regarding my need, is a good start or my goal will give me too much troubles?

I think you want to make enough changes that it would be easier to start from scratch and make your own version that suits your needs. You could use the one you got from the Warehouse as a basic reference and then delete it from the model space when you’ve got your own model created.

If you use the Scale tool on the box as you show, it will scale ALL of the geometry including the size of the screw holes.

As @DaveR pointed out, the scale tool scales everything proportionally. For a model with more than a bulk shape, that is usually not what you wanted. For example, wall thicknesses, hole diameters, those rounded corner posts, screw sizes, etc. will all be changed.

There are extensions for the desktop version that deal with this behavior, but they cannot be run on the web version. So, as he said, the path of least hassle is probably to create your own using the existing one as a reference only.

What is the name of that box in the 3D Warehouse? I did a quick search but didn’t see that one.

Depending on details of the model, you might be able to select parts of it and use the Move tool to change (for example) the overall height, width or depth, without changing the hole sizes or wall thickness.

Upload the model here, or provide a link to the 3D Warehouse model, to get more specific answers.

Or as @DaveR suggests, model it yourself.

Here’s a general idea of a workflow that will yield a solid object suitable for 3D printing. Don’t add features too early in the modeling process.

From left to right:

  1. Footprint of the box. The bottom of the box is smooth in this case so no other features are drawn while it is 2D.
  2. Extrude to the thickness of the bottom. Add the outline for the inside of the box and the screw bosses. Outline any other features such as internal dividers at this point.
  3. Extrude to height. Outline for the raised area on the rim. I put it outside the screw holes but it could just as easily be modeled along the inside as in the box you showed.
  4. Extrude the rim to height.

Holes could be added through the side with Push/Pull.

Hello, thanks all of your repliées.
Actually, I am not with my laptop. I am writing with my mobile. That’s the reason why I have not react yet.
I quickly red the Last reply from Dave with 4 images and will try later.

Just à note, before I am back home. The screw to close the box must be screwed from to top cover which is higher than the bottom. The best would be to have a rounded top cover.

But first, I will do, following of the 4 images of Dace .

Many thanks
(Back home in 3h)

Thanks for your comment.
Dave, I could make the top

However, I can’t understand how you make the round (see my second picture) as you did on your lastest attached picture.

You could use the native FollowMe tool to round the top’s edge.

But to avoid problems with small edges in SU, scale the model up 1000 times, and use metres as mm, or model in metres as if they were inches. If this is to be 3D printed, export as STL (which is unitless) and tell your slicer what units to import.

Thnaks John for your reply.
My problem, I never used Following Me and I have no idea how to use that tool according to my model. (The holes I drawed can be ignore for now)

I just change my top, to be likw a hat

If you look at the bottom view, the holes will be there. The bottom cover, will have like an arm at 90° to be fixed at a pole or a wall.

Is possible to see a short movie, how you would use Follow Me tool to make a round at the top ? (Like @DaveR veR did, in his exemple)

Many thanks and enjoy your week-end

There are many ways to make a rounded top, this is just one and I’ve done it this way to sort of explain a bit how follow me works.
I have a square with rounded corners, that is the ‘Path’
I have a single face that is perpendicular to the Path, that is the ‘Profile’
The two can touch, but they don’t have to, and each will produce slightly different results.
So I select the path, in this case I just use the face, but I could select just a continuous run of edges if I didn’t need it to go all the way around.
Once the path is selected I activate the Follow Me tool, at this point the chosen ‘Path’ will appear to become deselected, but that doesn’t matter.
Then click on the ‘Profile’ and it will follow the ‘Path’.
Also on this occasion the shape allows me to simply delete the inner face to fill the gap, this isn’t always the case.

Round top


Dear @Box
So many thanks for your movie. It’s helped.
I could manage it, but not at 100%. I have somethings strange

My rectangle has a ryaon of 10mm (I do not know in english, the half of the diameter). I wonder if it’s not too much.
Then I make the “Profile” with a rayon of 10mm, as well and the result is a bit strange, because “the corner are not closed”

What would I did wrong? I wonder if I should have a profile with rayon les important, may be as 5mm. Isn’t?

You are running into the tiny face issue, have a look here

By the way, Radius is the word you are looking for, half the diameter.

Ok, thanks a lot.
I scaled 10 time my orginal rectangle, as well for the origin and I used again the Follow Me tool.
That better, but I get that error

I check twoce: I place the orgin at the middle of my rectangle. My rectangle is 1000x1000mm, and then the origin was at 500mm, and 1mm above the rectangle. Then I selected the path and with the Follow Me tool, I clicked on the origin. Finally, I scaled back to 100x10mm.

It look nice with a Radius of 10mm, but I wonder if I should be worried about the warning

Warning, the path you have choose, does not begin or end at the Exclusion cross section, Unexpected result may occured

You can ignore the warning, in this case it is there because the path and profile do not touch. I get the warning so often I don’t even see it now.

Is a bit like, Warning Coffee may be hot.

Ok, thank a lot and to @DaveR as well.
I really learned a lot today with Follow Me, etc.

I have a last trouble

If I look at your scene, you deleted the vertical face to have top “closed”
If I tried it, it does not work

I think, it’s because I have a corner, instead of a small round (inferior)

I tried to have all Radius at 10mm. But may be, for the Profile, I should have some things like 8 or 9mm. I will try tomorrow, because it 2am now. With a rest, it would be better tomorrow.

In any case, thanks to all. It really learned

Double click the face so it selects the edges as well, then delete.

Sadly, it does not work
But I can see two angles

Somethings went wrong at previous steps. No worries, I will do it again tomorrow carefully.
It will work, I am sure.

Extend your profile a bit so it doesn’t end at the beginning of the curve.
You can always attach your model so I can tell you specifically what would fix it.

Here’s an example, if the profile ends on the curve removing the edge is removing the edge between two non planar faces, therefore removing them both. But if the profile is flat removing that edge closes the face.
