sKetchup Drape Tool (su7 ~ su2017 and possibly still su2018)

When I drape a few instances of a component at once it drapes only one… grouped not grouped or together with different entities… Same with groups if the groups are just copied end not even once opened to edit…
I guess it my be a problem with counting componetsdefinitions instead of instances by drape tool… (since groups have as well their componentdefinition)…
–edit–
Or maybe it is intention not a bug??

Double-click on the component group, select all, explode them, and then use Drape tool. It will work, I tested.

Ye thanks…
I figured that out… but that is a workaround. I didn’t look for solution just wanted rather report a bug… is it not wright place for that…?
my point is that sketchup should do drape without me exploding the components and groups inside… it is not a big problem but sometimes you work with files made by somebody else… can be big… you may miss some components not being dropped… exploding group’s content every time before drape (just in case …) is not what I expect from the well made tool. Good tool my need some preparation (grouping things which you want to drape), but shouldn’t need workaround
PS
How do you make this animation… taking a few screenshots and making a GIF out of those… ?

If you want to report a bug, you should add that to the tags.

It’s a little late to be reporting a bug in SU2016, though. Does it still do the same thing in SU2018?


#5

two ways I know of to make the gif: LICEcap (free) and Snagit ($$)


#6

I don’t have SK2018… but it works same way from SK7 ~ SK2017 Make… So I was guessing maybe they didn’t fix it yet in SK2018…
As well it is possible they have some reason for which they want it to be that way… just I can’t fink of what could it be…

The Help Article on Drape indicates that you need to select edges to drape, not groups or components. Based on that information, I would be inclined to think that draping the edges from inside groups or components is the bug.

See: https://help.sketchup.com/en/sketchup/placing-models-and-objects-your-terrain

Especially:

When you use the Drape tool, SketchUp transfers edges from a flat face onto a TIN’s curved surface.

Tip: To create the edges that you want to transfer onto your TIN, draw a rectangular face above your TIN. Then, draw the edges on the flat rectangle with the faces in X-Ray mode, so that you can see the TIN underneath. You can then erase the edges and faces you don’t need, leaving only the ones that you want to drape onto your TIN, as shown on the left in the figure (Callout 1).

When you’re ready to drape the edges, follow these steps:

  1. Select the edges you want to drape over the TIN.
  2. Select the Drape tool () from the Sandbox toolbar or select Tools > Sandbox > Drape .
  3. Click the TIN to drape the selected edges onto the TIN, as shown on the right in the following figure (Callout 2).

At this stage for you, unless you’re planning to upgrade to SketchUp Pro, it’s kind of a moot point, anyway.

I have Pro2016… same… I guess the intention was originally to prepare flat drawing geometry to drape it on some more complex mesh… they assumed getting only edges selected was part of preparation not to bother to much with what user may choose (or not choose)
I was treating it more like general purpose tool : grap whatever > drape on whatever… Actually you don’t need to group things but sketchup automaticly selects all connected for the TIN so I got the habbit of grouping the part of TIN that I need… saves some time when the terrain is huge…
