Subreddit guides combine public Reddit source URLs, captured rules, visible verification dates, and Rankhog's account-safety workflow.
Rule summary
No subreddit-specific rules were displayed on the public rules page when Rankhog verified it on 2026-10-28.
Works well
Share a plugin you built for SketchUp, framed as a question about how people handle a modeling workflow it helps with
Post a short walkthrough of a SketchUp modeling problem you solved, with the file or steps included so others can learn
Ask the community how they organize components and layers on a real project, then mention your tool only if someone asks
Share best practices for a common 3D modeling task and invite people to poke holes in your method
Answer other members' modeling questions in the comments for a while before ever posting anything about your own product
Show a model you made and describe how you built it, letting the technique be the point rather than the tool
Avoid
Dropping a bare link to your product with no context about SketchUp or modeling
Posting about a topic unrelated to SketchUp, plugins, or 3D modeling best practices
Writing a post that reads like an advertisement rather than a contribution to a discussion
Creating an account that only ever promotes one thing, which reads as spam even without a written rule
Being dismissive or unhelpful toward members asking basic modeling questions
Reposting the same promotional message across threads in a short window
What r/Sketchup Is For
This is SketchUp's home on Reddit. The public description says it is a place to discuss Trimble's easy to use 3D modeling program, plugins and best practices. So the people posting here are SketchUp users, and they come to talk about modeling work, extensions, and how to do things better in the software. That includes hobbyists, professionals who model in SketchUp for a living, and plugin developers. If your post is about SketchUp, a plugin for SketchUp, or how to model well, it belongs. If it is about something else that happens to touch 3D a little, it probably does not.
What To Post
A good post here looks like a person sharing something genuinely useful about SketchUp. That could be a modeling technique, a plugin you built and want feedback on, a question about best practices on a real project, or a walkthrough of how you solved a modeling problem. If you have a product, the respectful route is to participate first, answer other people's questions, and only mention your own work when it honestly helps the thread. A post about your plugin framed as here is how I built this and here is what I learned fits the room far better than a link drop. Keep the focus on the craft of 3D modeling, because that is what everyone here showed up for.
What To Avoid
There are no published rules to break, so the honest framing is that anything off topic or self serving survives only on the moderators' patience, and that can run out without warning. Do not post anything that is not about SketchUp, plugins, or 3D modeling, and do not treat the sub as a free ad channel. Do not drive by with a single promotion and disappear, because a member with no other presence reads as a spammer even without a written rule. Do not be dismissive or rude to people asking beginner questions, since the brief calls out being helpful and respectful directly. And do not assume silence on the rules page means anything goes, because moderator judgment fills the gap when rules are absent.
Use Rankhog before posting in r/Sketchup
Want the version that does not run out? Subscribers get unlimited tool runs and more careful checks before posting.
Start your 7-day free trial. Card required. $99/month after trial. Next, connect a verified Reddit account; no strategy starts until you explicitly start Rankhog.
The community has no published rules on promotion, so nothing in writing forbids it, but the moderator guidance says keep posts relevant to SketchUp, plugins and 3D modeling. A plugin post framed as helpful and open to feedback fits that. A pure advertisement does not.
Is there a rule against links?
No published rule addresses links, so the moderator one liner is your guide. Links are fine when they serve a relevant, helpful post about SketchUp or 3D modeling.
Are AI generated posts allowed?
There is no published rule on AI content. The safe read is that anything you post should be relevant and helpful to SketchUp users, so low effort generated filler is a poor fit even if it is not explicitly banned.
What happens if I post something off topic?
No written rule says what the penalty is. The moderator guidance asks for relevant posts, so off topic posts depend entirely on moderator judgment and carry unquantified risk.
Do I need to participate before posting about my product?
No rule requires it, but the moderator guidance asks you to be helpful and respectful. Building a history of genuine answers before mentioning your own work is the respectful path and it protects you when no written rules exist.
