Can I post about my BIM related product?
Only if you message the mod team first and get preapproval, because the “No Spam” rule says truly innovative products may be discussed after the mods agree.

Rule summary
- Posts should relate to BIM: Posts should relate to Building Information Modeling in some fashion - software, file types, hardware, related technologies, workflows, etc.
- Be respectful of everyone else.: Respect others. All comments should remain civil and reasonably professional in language. Any form of personal insults, hate speech, prejudicial language and bigotry are not acceptable.
- No Spam: This sub is not here for you to promote you or your business. It is acceptable to mention various solutions and link to reputable resources in answer to other users or to post actual research. It is not acceptable to post blog spam or astroturf promotional links. If you have a truly innovative product that you feel the community would like to discuss, message the mod team for preapproval.
- No employment spam.: Job seeking is not allowed nor are entry level job postings. Job postings are acceptable for more senior roles but should contain enough relevant information in the post, and not be marketing spam. Job postings should be removed after the role is filled.
Works well
- Answering a practitioner's question about a workflow or software choice and mentioning your solution only because it genuinely helps
- Sharing actual research, like a technical study or benchmark related to building information modeling
- Messaging the mod team for preapproval before posting about a truly innovative product
- Posting a senior level job opening with full relevant details, then removing it once the role is filled
- Linking to reputable third party resources when they answer what another user asked
Avoid
- Posting a link to your own blog or product page as a standalone post, which the “No Spam” rule calls blog spam
- Writing fake casual posts that praise your own tool without disclosing you made it, which the “No Spam” rule calls astroturf promotional links
- Announcing your product launch in the feed without asking the mod team first, when the “No Spam” rule says innovative products need preapproval
- Posting an entry level job opening, which the “No employment spam.” rule does not allow at all
- Posting a job ad for a senior role that is really just marketing copy with no real details about the role
- Leaving a job post up after the role has been filled, since the rules say those should be removed
What r/bim Is For
This is a community for people who work with building information modeling. The public description says it plainly: a place to discuss all things BIM. The rules fill in what that covers, so think software, file types, hardware, related technologies, and workflows. The people posting here are practitioners who live inside these tools and processes every day, and they expect posts to connect to BIM in some real way. If your post has nothing to do with building information modeling, it does not belong here no matter how good your intentions are.
Rules That Matter Before Posting
The rule that decides most marketing outcomes here is “No Spam”. It says the sub is not for promoting you or your business, but it allows mentioning solutions and linking to reputable resources when answering other users, and it allows actual research. It also gives one clear escape hatch: if you have a truly innovative product the community would like to discuss, message the mod team for preapproval. “Posts should relate to BIM” matters next, because anything you share has to connect to building information modeling in some fashion, whether that is software, file types, hardware, related technologies, or workflows. “Be respectful of everyone else.” sets the tone for comments, so keep language civil and reasonably professional. “No employment spam.” matters if hiring is part of your marketing, because job seeking posts and entry level job postings are not allowed, while senior role postings are fine if they carry enough relevant detail and get removed once filled.
What To Post
The safest and most effective posts here are helpful answers, not announcements. When someone asks about a workflow, a file type, or a piece of software, and your product or a reputable resource genuinely helps, you can mention it in your answer. That is written into the rules as acceptable. Sharing actual research is also allowed, so a real study, benchmark, or technical writeup with substance is a good fit. If you have built something genuinely new for the BIM world, do not post it cold. Message the mod team first and ask for preapproval, exactly as the “No Spam” rule describes. A senior level job posting can work too, as long as it contains enough relevant information about the role and you remove it once the position is filled. Whatever you post, keep it clearly connected to building information modeling.
What To Avoid
The fastest way to get removed here is to show up and promote. Blog spam and astroturf promotional links are named directly in the “No Spam” rule, so do not drop links to your own blog or post glowing writeups of your own product while pretending to be a regular user. Do not post about your business at all unless you have messaged the mod team and gotten preapproval for a truly innovative product. Keep every post tied to BIM, because off topic posts get removed under “Posts should relate to BIM”. On the hiring side, never post a job seeking message or an entry level job opening, and if you post a senior role, include enough relevant information and take the post down once the role is filled. Finally, watch your tone in comments, because personal insults, hate speech, prejudicial language, and bigotry are all unacceptable under “Be respectful of everyone else.”.
