Scan-to-BIM can be much faster – Povilas Sindriūnas, Undet

In Povilas’s words

“We have to come and meet them where they are, because we are not Autodesk, and we're not going to be.”

Quoted in our tech guides

Scan-to-BIM: from point cloud to Revit model – what 7 practitioners say →

“The biggest amount of time is spent in registering point clouds and then turning them into usable assets, be it a BIM model or a set of 2D drawings.”▶ 2:56
“You don't want to deal with the entire RCP file in Revit or AutoCAD, let's say, and we have tools that help you slice up the point cloud.”▶ 23:22
“Ideally, you would be working in a 2D view, let's say a floor plan.”▶ 26:27
“We have to come and meet them where they are, because we're not Autodesk, and we're not going to be.”▶ 20:00
“What is beneath expectations are the standards.”▶ 63:34
“Basically the software overlays your Revit model with the point cloud, and based on your parameters, you can tell how well something has been modeled.”▶ 44:13
“The easy way out is less of a philosophy at Undet.”▶ 75:04

SLAM vs terrestrial laser scanning: what 8 practitioners say →

“Most likely. I don't see any other good or viable alternatives to SLAM.”▶ 6:31

Questions Povilas answered

What is the biggest bottleneck in scan-to-BIM projects?: Per Povilas Sindriūnas of Undet, scanning keeps getting faster, but most time goes into registering point clouds and turning them into usable BIM models or 2D drawings. ▶ 3:08
Will SLAM scanners dominate as-built documentation?: Povilas Sindriūnas says most likely: SLAM makes scanning more affordable and faster, and Povilas sees no other viable alternative for that trend. ▶ 6:30
How can you work with large point clouds in Revit without slowing it down?: Povilas Sindriūnas explains that Undet for Revit slices the point cloud per view and references it as colour-coded raster images weighing kilobytes instead of loading the whole RCP file. ▶ 23:14
Can walls and windows be modelled semi-automatically from a point cloud in Revit?: Per Povilas Sindriūnas, Undet’s Fit Wall tool places a wall with three clicks (start, end, thickness) and creates a missing wall type, while Fit Opening inserts a window or door with two diagonal clicks. ▶ 35:04
How can you check a Revit model against the point cloud for missing elements?: Povilas Sindriūnas says Undet Browser overlays the Revit model on the point cloud and, based on set tolerances, colours elements that are missing or inaccurate; a reporting feature is on the roadmap. ▶ 43:28
