Hybrid Mode causes "lost" lines when geometry is viewed behind transparent or water surfaces

It has not been fixed.

It is doable with overlaid scenes, but I have to hide the transparent faces to get a usable hidden line scene

so frustrating still not being fixed…I’m no programming genius, so I can’t comment on “why” they haven’t addressed this bug yet… Hey…@Trimble are you listening?

If only my models were that simple…but thanks for giving advice Mr. Anssi

I’m on SU2020 v20.1.228 on a Mac and this issue seems to still exist - just transplanting my recent post in another thead relating to this:

By reading all the workarounds, that’s great but that shouldn’t be the way we’re spending our time with LO. Hopefully it’ll be looked at and is a relatively simple fix that doesn’t break a bunch of other things. @Trimble ?

Unfortunately…this seems like a fix Trimble is NOT too overly concerned with fixing anytime soon. Its frustrating because I use SKP PRO as an Aquatic designer, and having water (transparent) surfaces is almost 100% of the time in my models. The work-arounds are time consuming and just that…“a work around.”

It bugs me that if my screen can show a perfect render of lines and shadows both behind and beyond transparent surfaces, then why does Layout struggle to replicate the same imagery…I mean are they not meant to be companion software, both utilizing the same GPU and CPU, but in LO we have to choose between 3 “modes” of which none actually come close to capturing what the screen shows in SketchUp.

My work-around is to take screen shots of the image in SKP and then import them as an image into LO. It only works on perspectives and…where I don’t have to dimension any views…ugh!

This and the NEW subscription pricing model, may finally force me to abandon SKP after nearly 16years of using it. Double UGH!

Totally agree - I think it’s just that the majority of Pro users do not need to output viewports in hybrid or vector which I can see why but for those of us that do, it certainly is annoying especially when it should just be something that is by default. Below, my response to @colin to this issue in another thread:

Well, it looks like you do some excellent work in your field, displayed by your screenshots above and it would be shame to lose a pro user like you to another software but with the new subscription model and other mounting annoyances that plague LO and its integration with SU on so many levels, it’s easy to see why after so many years, you’re finally at that tipping point.

Thanks for your comments on my work. I fell in love with SKP from the very first beta offering back when it was owned by AtLast software. It was a perfect match for how we “bend” sheet metal, and manufacture our Stainless Steel vessels. It served well as a very quick modeller for Concept Development with the ability to export to .DWG and .DXF formats for further construction models in SolidWorks, AutoCAD, etc… Over the early years it progressed nicely with subsequent version updates, with decent improvements and additions to the main software, nearly all of the time justifying the increases in its cost.

Now, like many others on here…I’ve seemed to reach the “tipping point” as you mentioned. Any users, and especially the PRO users, now have to decide whether to jump ship once and for all…or roll the dice (once again) and hope for future release versions to have more than one or two obscure features, when its something that is relatively basic and standard on other 3D platforms, …in order to justify the perpetual $$$ outlay.

As a designer, my job is to design, not trouble shoot work-arounds, or find ways to accomplish basic imagery or understand the intricacies of managing, updating and verifying certificates for numerous add-ons, extensions etc…I appreciate the 3rd-party dev peeps, but again I feel SKP development team has lost site of the PRO users, and our need to keep abreast with other 3D software offerings.


Ok I think I have finally figured out the best work-around for this issue.

  1. Compose the view for the scene to send to Layout
  2. Make a NEW Tag for the transparent surface, be it “Water” or “Glass Windows” etc…
  3. Create one scene with Edges & Profiles off - thereby leaving on ONLY solid materials, shadows, etc… Call it “Solid Fill”
  4. Create the SAME scene in “Hidden Line” in SKP, but this time with Edges On and Profiles On (no fills, just black and white line art) …Call it “Lines Only” BUT make sure to turn OFF the Water/Glass Tag view in THIS scene
  5. In Layout, stack the the “Solid Fill” scene on the bottom in RASTER mode.
  6. Then stack the “Lines Only” scene on top in VECTOR mode.

For some reason the Lines Only scene in Vector mode with the Water TAG off, lets the solid fills and materials, “Show through” what is in effect is the other solid areas that aren’t water or glass.

Don’t ask me why…but it seems to work. Any thoughts DaveR?

Still… you’ll now have two scenes for every NON Plan or Elevation view in Layout…but at least the darn Jaggies are gone!

Don’t know whether the attached image does the end result justice, as I have to down sample the image in PSD in order to have a smaller file size to post here.
