BIMIT Plan

Overview

BIMIT Plan is a fully automated 2D floor plan generated directly by the BIMIT Engine from point cloud data. This deliverable provides clear, professional architectural drawings in both PDF and SVG formats, created entirely through automated processes.

The BIMIT Plan represents a complete 2D architectural floor plan that includes:

  • Wall layouts: Accurate representation of interior wall configurations
  • Door and window placements: Accurate location and sizing of openings

Output Formats

Current Capabilities

BIMIT Plan currently supports the following interior building elements with full automation:

Frequently Asked Questions

Why haven’t I received my plan yet?

The pipeline likely failed at some point. The common causes at the moment are:

  • Exterior elements in the point cloud are causing errors
  • The model was far denser than we were expecting
  • De-compression ballooned the file and it caused issues in the early part of the pipeline

You should see an error status in the IPX portal related to your order.

Does decimation matter in the point cloud we’re submitting?

Ideally, decimation should be at a minimum, between 15mm and 20mm. In general, decimation is not critical to the results.

Most projects will have ‘ghosts’ of data, especially live job sites with workers walking around and cars/equipment moving. Will this impact the results?

This is fine to include. Pre-cleaning is helpful but also not critical.

Is there a size or complexity limitation for conversion?

Size of the file impacts the turnaround time for now. So a 15 GB point cloud might take 2-3 hours to process compared to a 1 GB point cloud.

Complexity doesn’t matter as much, however, we currently do not handle exterior-only scans very well.

Do you ingest SLAM data as well?

Yes, we can take in point cloud from SLAM and LIDAR. The only limitation is that it should not be a phone-based scanner for better results.

How are levels handled?

Levels are automatically generated and created.

  • If the order is in Metric, the Levels will start at Level 0, if Imperial, Level 1
  • For every Level we create a Floor Plan and RCP view
  • We also currently apply a Top Offset to each wall

What if there are missing elements?

We are currently developing mechanisms to benchmark what we would call Completeness. Our model does have some false positives and some false negatives. We estimate about 90% of the elements in the point cloud will be detected and modeled. Over time, we will improve the consistency and coverage.

What version is the model produced at?

We plan to produce these models for all Revit versions supported by Autodesk. However, we only support the oldest year that Autodesk will support in the current year.

What if I want a fully completed model?

We do have two services to support companies that would like to augment their capacity with quality deliverables that have been rigorously QAQC’d.
