Adding textures to objects


Any advice welcome.

Not sure how to upload my drawing for someone to investigate but…

I have drawn a floor using 18mm sheets of ply. The floor is on 2 angles, the main floor and a front section ( and a small wedge joining). I pushed pulled each panel which Im sure is not the most effieict way but couldnt work out how to cut around the outline.

Anyhooo…I need to now ‘paint’ each sheet with a black ply wood grain, which i have in my paint bucket. The grain is the wrong way and I know to right click to texxture and use green arrow to rotate the grain/texture.

But…how can I efficiently paint every sheet, and its egedges and undersides with out painfully painting each sheet, and rotating the texture each time???

Thoughts wonderful people?

Drag and drop your .skp file from your hard drive into a response window here. An efficient answer depends on how your floor heads been modeled. Are your sheets of ply instances of the same component?

Actually I can see from your outliner that they are, that’s good. Upload your file and we will take a look.

Im still just getting my ahead around the basics…getting there…

erm…how do i drag an .skp file?

i saved the floor as one whole component…on reflection a bad move…

No problem. I’m talking about the .skp file on your hard drive. Save your model, then exit SketchUp (no need to quit it), navigate to the saved file on your hard drive and grab it and then drop it into an open response window.

Or use the 8th icon across the top of a response window to upload.


ope this works!

Yes, not the most efficient way. Better to make a single sheet a component. Then you can leverage the interconnected nature to components to change them all by only editing one.

Yes that worked. Taking a look now…

Well, I would re-model as components to save yourself some headache and make you future easier. But if you want to push it though as is you can paint one surface and edit it to your liking, then sample it (paint bucket with modifier key) and apply it all the other faces.

A bigger problem here is how you are using Tags. Only groups or components should ever be assigned a Tag. All raw geometry should be untagged and the pencil should never be moved off of untagged in the Tags window. Tagging raw geometry can and often does destroy models.

Thanks so much for your time here. If I do push through and use the eyedropper, presumably that would only change the orientation of the top face? if so Ill remodel as components.

To be honest I am SO confused about tags, groups and components. Here is where I am at after several days of hopefully useful research…

  • Groupe everything as components, in the long run this is much more useful then groups and gives you more flexibility in the future. So Ive been trying that and it really helps me with keeping track of things in Outliner (which Ive just discovered). A good way to make sure titles and headings etc are the same.

Also read that until I am an expert to avoid tags and stick to using outliner.

The tags in my model are from my early days when I thought I had to add a tag to every group. Ive tried to clean it up.

PLease can you explain how I should use tags? For now should evrything just be on the first untagged tag?

It’s a lot of new terms and ideas in the beginning but it will soon all fall into place. I’m on my phone at the moment but are some group/component resources.

Thanks again for that, Ill follow the link. If you get a sec…I have started to repeat components, made unique where necessary…

Here is where I get into difficulties…

How can I lay a black ply sheet on this area and be able to use the shaope to cut out around the theatre proscenium???LA CAGE AUX FOLLES SU PLANS.skp (7.0 MB)

You have the shape already.

Window select round it to select it all, then g (shortcut), or R-click/Make Component.

Go to one of your existing black panels. Open it for editing, start the paint Bucket tool (shortcut b), press and hold the Command key (on Mac), to sample the black.

Close that component. Re-select the irregular component you’ve just made. Open it for editing (double click it, or R-click, Edit component).

Press b again to reactivate the paint Bucket too. Apply it to the top face and edges. Or preselect them by triple click when the component is open for editing, then apply the paint Bucket.

Do the same for the small irregular part next to the larger irregular panel.

I notice that your ply panels have skewed axes (shown here for clarity in Monochrome)

You should open any one of these component, Change Axes, and reset the axes at one corner, along the edges of the panel.

Also, see the post I recently made for another beginner in SU.
Help getting started.
You may find it helpful in dealing with components, naming, and the use of tags.

I notice Z-fighting on all your rectangular black panels. (They shimmer as you orbit around). Looks as though there are two faces in the same place ‘fighting’ about which one should be shown as higher in the Z-direction.

Yes, there are. You haven’t deleted the original face of the floor. This is what I see when I turn off the tag for the panels - 8 X 4 PLY SHEET STAINED BLACK

Delete the parts of the floor you have replaced with unitary panels (that’s pretty well everything else).

But part of the floor is the piece I just made into a component, showing black.

I see in Outliner that you have given the same Instance name to all the floor panels, whatever their size. They aren’t all now 8x4 panels -some are smaller or irregular.

I don’t normally bother with instance names at all - you could delete them all without loss. Or, if you want to be clearer which are small rectangular ones, you could give those a different Instance name, depending on their size and orientation.

Hello colleague!

I also design theatrical scenery, so I understand what needs to be done here. However, in my experience, the design and visualization of elements (such as the floor) are two different things. In the case of a painted floor (especially if the border of the pattern does not coincide with the border of plywood sheets) I usually make a separate sketch, but I do not mix it with the structural part, but use only the outer contour of the area. If necessary for the painting, I cover the floor layout with the 1x1 m grid (which usually does not match the contours of the plywood sheets) from the center of the stage 0 line.

The requirements for drawings in theaters differ, so I would like to understand for what purpose you will use the resulting floor model? For carpenters to make it, to visualize the stage space, or for both purposes? Specific recommendations would depend on this.

In some models I have added an additional component to the floor (1-2 mm thick), which I painted according to the sketch, in others - painted the whole floor as a group, not each of its individual plywood sheets.

I often use the option to replace the color of a particular layer (now - Tag) with an image of the required size.

The attached model shows 2 variants in which I have combined both techniques. One has an appropriately painted Tag assigned to the additional component (style option Color by Tag is switched on), the other has the entire floor painted as a group (style option Color by Tag is switched off). Go through the scenes! Each of these methods has its pros and cons.

P.S. I don’t touch the sides of the floor, because I think it is more rational to make them from larger plywood, because they are very narrow.

Thanks so much John, this is really useful. Wuld you mind clarifying the axis part? the floor is on an angle is that why the axis are skewed?


Thanks for taking the time to show these examples, that does make sense.

Your organisation is really clear.

Im juist trying to learn the basics before moving onto specific usage for my models…

If you just accepted the default axes, yes.
