Fog in Sections

A bit of advice needed.

I’m designing a multi story building with a mutha load of interior sections/elevations

Each floor is a separate sketchup file with about 15-20 scenes tied to a very comprehensive Layout file

My boss hates the single line thickness look (he’s pretty old school) and I’m trying to make the far end of the section view look greyer (more faded) than the front - hence fog

I cant work out how to tweak the fog so the Skalp fills look sharp and the exact place in the background is perfectly faded without messing up all the scenes. I realise I can overlay viewports but this would literally double my viewports

I have tried Eneroth’s fog placement tool, along with camera memory but as soon as the scene rotates back the fog placement is messed up. If you try manually the sliders are so small it’s impossible to achieve.

Anyone got a better method?

fog is saved for each scene, right? I know the control has always been rough, but if you go to each scene, set the fog, you can update so the fog works in that scene

The lack of line quality is something I dislike about SketchUp. You can work on your line weights in LayOut but it would be a daunting task I suppose. Lineweights are not just old school, they really help make a drawing readable.

Skalp has depth clipping, doesn’t it?

Yup, it is. It’s getting it to look consistent and not wash out the Skalp that’s the problem

I’m a big fan of line weights; I believe Vectorworks does this best!

Thanks Mike; I’ll have a look at this this morning - I also never realized the Skalp guys had a manual! I’ve been using it since I met them in Basecamp in Boulder before they released it and never kept up with all the additions!

You and many others! Now that we have the longed for broken lines, it is clear that it is possible to have different line (or edge in SU terms) attributes. So why not lineweight and linecolour too? Come on Trimble, sneck up!

You can already colour edges ‘by material’ and then choose your material colour for them.

The problem with lineweights in a 3d model is the proper relationship of weights would depend on the view. “Profiles” is intended to help with this, as well as express rounded faces. However the result is every tiny step receives the same “Profile” treatment, defeating the lineweight effect in most cases.

As far as “Depth Cue” is concerned, I’ve never understood what the effect of that is supposed to be.

I only find it really important in 2d views. I think it is something that needs doing in LayOut but it doesn’t seem that it can be interactive with changes to the model, so every revision requires “retouching” or redoing the line weight enhancement.

I find myself just adding just a few heavy outlines to some problem places later in the process–where the 2d drawing is “flat” and not clear due to the sameness of all edges and surfaces.

My ideal would be a range of lineweights and a range of “conditions” either in a style or a LayOut assignment to the viewport. Is it based on overall relative positions in the scene? Such a computation might slow down LayOut a lot but we’re not worried about that, right?

You hit tit again @MikeWayzovski !

@Guy included it… genius.

Sure, John, but there is no way to alter the attributes of a particular line. Even the broken line options have to be tag applied. If that is the maximum flexibility we can have, why not enable colours and weights also to be tag enabled. @pbacot makes a good point about the view affecting things but I am sure that can be accommodated. I bet no one saw broken lines coming until they got here!

Jason,

Just use our depth Clipping which sets the fog from the sectionplane.

Guy

It’s awesome @guy ! When did you add it?
I’m back to using SketchUp full time now because I have moved to creative design again after 4 years.

Guy, how do I make my section fills have unique patterns like this? I would like to display different materials with different patterns (solid wood, plywood, MDF, sheetrock, etc), and I have been manually drawing over my sections in Layout. Your way seems better.

thats what the Scalp extension is for.

Without Skalp, you can create a face that fills your section cut ( you can use, for instance, TIG’s SectionCutFace extension) and paint your patterns on that.
That is what I used here:

like @Anssi tells you can use section cut from TIG which is a great and free extension.

But Skalp does much more than this free extension:

  • Live section full
  • Assign sectionmaterials based on different rules: by object, by tag, by texture, by label, …
  • Pattern generator based on AutoCAD pattern files
  • Different scales
  • Different materials for the same sectioned object in different scenes
  • A special hiddenline mode with textured and colored section combined with the model in black and with like a real drawing
  • Depth clipping (discussed in this topic)
  • Different Section cut widths for each sectionmaterial
  • Rear view projection lines
  • DXF and DWG export with real AutoCAD patterns, line weights and linestyles and all objects on the correct layers
