Let’s say I have a .DWG import of a floorplan.
Let’s say it has the AutoCAD hatches / fills in it. A LOT of hatches/fills.
Let’s say it starts dragging Sketchup to a crawl.
Since it’s a CAD import, there are no Groups or Components.
So is there any way to delete every instance of a SHAPE that matches a specific example?
Either Sketchup built-in method or any extension anyone’s aware of?
Looks to me as if there’s more to delete than keep. Select what you want to keep, invert the selection and press Delete.
It depends what SketchUp converted them into. If they are components, you can locate the definition in Components browser, right-click and select “Select Instances” and delete. If not, they are just edges.
Can’t you use outliner to identify the groups and delete them from there?
I usually do some clean up in Affinity Designer before I import - either PDFs I convert or files I get from a client.
Still tedious, but I can somewhat quickly get a lot of the hatches and stuff selected and deleted.
Deleting Tags and their associated geometry is also useful.
I wish there was a plugin to select geometry of a certain size - length range for lines and area for surfaces. Would make quick(er) work of this process.
It makes me think of the “blockify” command in bricscad. If you turn any shape into a block, this autocad clone will scan the whole model space and turn any similar shape into the very same block. Easy to then delete / modify etc.
Of course I understand you don’t have autocad or similar if you run into this issue, but it also means the drawing is badly done. Hatches should be on a separate layer and it is then quick to hide the tag in SketchUp or even right click > select all on same tag and delete
I use Affinity Designer too. It’s easy to select all items with the same color and line weight and group them or delete. After that you import a cleaner dxf file.
If it were components, I wouldn’t be asking… 
Bro you have no idea. With every architect that we have to work with on pretty much every project, it’s the same story. Even the ones who DO care enough to make layers, do that for the “principal” objects, but when it comes down to “housekeeping” the small details (or at least what THEY think are small details, they become a huge problem with Sketchup), it’s an uphill battle every time.
I even showed some of them on Zoom, what it looks like and how it behaves, and I’m CONSTANTLY asking for exports in DWG (not PDF), and WITHOUT hatches or fills or dimension lines. It’s like some Architect Amnesia, it might work for one response, but future documents go back to the same issue. eye twitch
This is just a tiny closeup, like 2 feet out of a 6,500 SF house… from the overall view, the problematic walls appear black, there are so many of these little “tailed circles”…
Can you post one of these DWG files you get? I wonder what those shapes are originally supposed to be. When I test, SketchUp either ignores hatches or then creates faces out of them.
I’ll have to try that. I’m very proficient in CorelDRAW, and it does have a function to find objects with the same attributes. But it’s opaque on the surface (no controls for similarity, etc, just a “trust me bro” user-interface approach), and if you crack the VBA code, it’s a bit of a syntax nightmare.
UPD: just looked at it and it looks pretty slick. And it’s a $ 69 ONE-TIME payment, unlike the subscription model that Adobe & Corel screw people with. Thank you for the tip!
There’s a bundle that replace photoshop, illustrator and indesign…
No subscription and easy to use
Maybe this could help:
o.O this could work! Thank you!
