Procedure to work with inserted items from 3d warehouse


#1

I don’t know how to work with the part such as a drawer knob once it’s placed into my workspace. One came up with a cube around it. Do I need to make it a component first or what? I see it in my components also.

Thanks

Anything you download from the 3D Warehouse comes in naturally as a component. Depending upon what the author has done, you may need to repair or clean it up. Give me an example of a knob component you’re trying to use.

Called small brass knob in 3d warehouse.

Thanks

The cube you see around it is the bounding box indicating that what you brought in is already a group or component.

To move, scale, or rotate it as a whole, you can work with the bounding box. To modifiy the geometry of your knob in other ways, double click on the bounding box and you’ll “open” the group or component for editing.

Is it the one by “davidheim”?


#6

yes

Thanks

OK. He’s left some guidelines in the component which make s the bounding box quite large relative to the knob. Edit>Delete Guides to get rid of the guidelines and then you should be able to zoom in on the knob itself.

It needs a little additional adjustment, too. The component’s axes are a long way from the knob. The best thing to do is right click on the component and choose Change Axes. Then set the origin at the back of the knob on the center which is marked with a few lines.

Thanks for your reply

After you’ve fixed the axes and origin location, you can easily insert the model onto a drawer or door by dragging it in from the Components window.

Once you’ve fixed up the knob, save it for future use in a local collection.

If this is only a small part in a larger furniture model, and only needs to ‘look good’ I’d redraw the knob with FAR fewer segments - this is absurdly over-detailed unless you want to 3D print it.

Something like this might do instead

Knob - simplified.skp (76.4 KB)

It’s still quite large for a small component in a larger model, but down from 345KB to less than 80Kb.

And reduced from nearly 3600 edges to fewer than 500.

I don’t agree with you on that John. While you could use a simpler component like yours, this knob is not “absurdly over-detailed”. It’ll work fine for a plan or a proposal. It might be overkill if the knob was being used in a house model but this one is intended to be used on a smaller piece of furniture or on a jewelry box where it’ll be more prominent.


#12

You’re right, I’m probably exaggerating - it would be fine for a single piece of furniture, and the original does look very much smoother in close up.

I’m probably over-reacting, after my experience with Scott Baker who had hundreds of copies of furniture components in his RiverArch model, in which a knob would only take up a few dozen pixels in most views - fewer pixels than faces, almost certainly!

Perhaps I’ve gone too far in reducing the edge and face count, but I still think it could be reduced by at least a factor of two and still look very good.

But might well not be worth the effort to redraw, if there aren’t too many copies in the overall model.

Your experience is much greater than mine, Dave, both in SU and in furniture making, and I certainly don’t want to quarrel with you - I’ve too much respect for your judgement ever to want to do that.


#13

Yes, it would be one thing if it was on a piece of furniture in a larger model of a room or a whole building. In that case even your version of the knob would likely be overkill. Based on the OP’s other posts, he’s only working on a model of a small table so his application can stand a more detailed knob without needing to worry about bloating his model.

If was drawing a model of a piece of furniture for others to look at as I usually do, I would invest a little more in details like pulls and knobs. The pulls on this piece, for example.

If I was drawing it for my own use as a plan, I wouldn’t bother putting the pulls on it at all.

Indeed - and they look great.
