Using Clear Materials - Skill Builder

Get a few tips about using clear geometry, erasing lines, and grouping! Check out this Skill Builder, whether your new to SketchUp or an expert, there is something for everyone!

Seemingly simply, but actually invaluable! Thanks Aaron and the entire SketchUp team.

Well that helps Arron, and I like it. I’ve been doing basically the same as you demonstrate but I was raising the swing component up 1/128” off the floor so it wouldn’t share the same space as the floor. Now I can illuminate the raising part.

PERFECT! Been having this exact hassle. Also really liked the shift-erase=hide. Been using SU since v1 @Last days and have never caught that! Instead I’ve been right-clicking my brains out to hide things

A Send Foreword or Send Backward priority would sort the Z fighting, let the user decide which surface has priority as many other graphic apps have

[gusbert]

Z-fighting comes from 3D graphics rendering. During rendering, every primitive has an x, y, z coordinates. Traditionally the z coordinate holds the value for the distance of the primitive from the "camera". If two have the same (or very close) z values, the renderer does not know which one to show. Expanded over two surfaces, each "pixel" is rendered essentially randomly, resulting in the flickering patterns.

Thanks Aaron, not a specific problem to me, but a nice solution for another issue I had.

Why not use the Hide command on both (line and surface)? I think this is easier for the rendering engine, rather than dealing with a transparent material.

Thx 🙏 a lot Aaron! Helpful!!!

Q: How to avoid that a copied element when modifying it does not modify the original?

[marakony]

7:40 - yes, yes, yes yes yes, yeees, definitely yes! )) there's even an extension for that CLF Loose to Groups

[markyspark]

very clear! Many points here I will use.

Thought I was coming here for a video on materials like glass or lexan--I was wrong but still learned something. A kin to finding out about reverse faces (y)

[Skans-Gustav]

Would grouping alone solve the problem without making the surface see through?

[garyspeed]

but you made it a component :)

I just lift the door swing 1cm above the floor, no need for a surface.. (goes into a "2D-plan" tag) mainly because I am concerned about all the additional overhead a surface adds to the model... not unusual to have 500 doors in a highrise model.. I have found even 2d linework disappears when on a 3d surface, , might be a graphic card problem.. but separating their z heights avoids that problem.. PS, I use "erase Stray lines" option very carefully

[richardvankesteren]

Thanks Aaron, I usually put the 2D-components on a TAG called 2D. I not like to see 2D line work when put materials on surfaces.

For a future video:
How do you use "REDRAW" in Dynamic Components? Like in your intro...
I can't find anything on YT on it.

[PeteCollingsArchitect]

Why not just group (or component) the 2 lines? Will "clean-up" delete them if they have been grouped or component-atized? *

[normanmcintosh]

Thanks Aaron, can you tell me where to find and how to use “clean up” please. I sometimes find I’ve picked a line (turns blue) then I erase it but it still shows. Only way I seem to get rid of it is to come out of file and go back in. Is there an easy refresh button ? I’m new to this so please excuse my lack of knowledge. Learning every day tho with your great tutorials.

[bengorraou]

i usually just group them and put them in their own layer

[randomscandinavian]

So I guess this is the last time we see the old logo? The new one is... well... I liked the old one. :’(

[DidierScheurer]

Not sure... we need to groups geometries ? Groups. Groups groups groups and... groups. i laughed too much 🙂
