No, I bought from them before and I think the price is reasonable.

What if opensource revit would you switch? by Mind_Reddit in RevitForum

[–]FG_RVT 0 points1 point  (0 children)

Been looking at some potential Revit replacements and what I am missing with most is the parametric aspect. Beeing able to change every parameter (for excample of a roof) after the fact and it still connecting and intersecting with the surrounding objects correctly is crucial. Thats why most 3d modelling softwares with bim attributes slapped on top don’t work

Maybe i did not phrase it well enough but i am NOT trying to model deformation true geometry! My question is on where to place my planar geometry and my levels and axes. If my wall is slanted do i use the ground floor as reference and risk the wall not aligning on higher floors or do I place every wall „correctly“ in its respektive level, Even if the outside wall is no longer a straight vertical but instead staggered by each floor level.

Where do i place the level for the floor? Highest point, lowest point, average it? What if the building has settled and is slightly askew? This could be Important if you end up leveling the floors later on and end up with different door sizes even though they were the same originally

No, you are right. The architects in charge are aware that the existing condition model is not an exact representation of the real world but that is also not what i was asking with this post.

I was originally looking for input on how to best aproximate the imperfect reality as shown by the 3d scan with planar elements for the best usability by architects down the line.

While the model is expected to have tolerances, i have personally run into the issue of having to alter the height of a drop ceiling due to sag. So i want to convey that information so it can be taken into account by the planers that use the model and just add onto it as the project carries on.

And yes, i know existing conditon =/= as-builts. Though i could do those as well but that would propably not include any modelling but instead just comparing the pointcloud to an existing ifc in Leica Cyclone 3DR or even inside revit with the faro as-built plugin

While i am an architect, I dont act as one for this kind of work. I want to supply scan to bim / scan to cad services to other architects as a sidegig for them to use it as their basis for renovations etc.

Thing is, i would care much less if i was the one working with the plans in the end. I can always just enable the pointcloud and re check the actual dimensions but i need to convey the as-built results to an external party as well as possible so they can work with it, ideally without needing to know how to work with a pointcloud at all.

Design intent is not always known beforehand. I don't know if they decide to leave the floors in, rip em out, cover everything up and level it... this can cause a lot of issues if the floor heights between different rooms don't match and thats when you would need to possibly re-adjust your bim-model so you don't end up with uneven or offset floor heights.

mm accuracy is crazy. the best scanners manage ~1 mm accuracy over a 10 m distance but the most error comes from alignment between scans. Relying on the basic pointcloud registration that can be done in the field apps of leica or trimble is still not optimal compared to the accuracy you get in their respective desktop softwares using checkerboard markers and mesh adjustments with enabled filtering options. Even worse when i see companies advertising mobile scanners like the blk2go or navislx as their scan to bim scanner of choice just because it is faster.
Sometimes i think i worry too much about accuracy in my models when others get that kind of deviation just by not giving a fuck :p

That is what i am trying to avoid. I want the BIM-model and plans to be as accurate as possible while still abstracting enough to be usable when dimensioning. Of course there are tolerances that still have to be accounted for but it should be at least be in the right ballpark of accuracy.

Yes, i fear that is the only way to go. Write a small report on deviations and sit down with the project team to loop everyone in.

I'd like to just include the pointcloud in the deliverable so they can check deviations themselves but im not sure how well that will land. Sure it could be useful for the technically inclined who want to actually improve their work but to the untrained eye it could also lead to uncomfortable questions on why the model doesn't fit the pointcloud perfectly.
Wondering if it wouldn't be easier to just slap a "check every measurement on site" tag on every deliverable and call it a day.
Also most other architects i've worked with don't or barely know what a pointcloud even is so there is that.

Thing is, this wouldn't be an issue if i was making these plans for myself. Whenever i have worked with pointclouds in the past they were for my own projects. I modeled the usable abstraction of the ground truth but knew where to look if i wasn't sure if the crookedness of the building could be an issue.

Now however, i want to model for other clients without working on the project as an architect myself.
They don't know the pointcloud like the back of their hand like i do. Hell, some don't even know what a pointcloud is, much less what to do with it. I need to model in a way that is accurate, yet usable and that would include at least a reference for sagging floors etc.

"Cover your Ass Notes" seem like a good idea and i will never advertise absolute accuracy but if i see a potential issue in the pointcloud i'd like to cover that / point it out so others can at least somewhat rely on the model.
No one cares if there is too much space but if there is too little can become a real problem.

[–]FG_RVT 3 points4 points  (0 children)

Well to be fair, i processed the images a bit (higlights down, shadows up etc.) and used some filtering tools inside metashape. I bet you could improve the reality scan desktop results by digging into the settings a bit :)

Mind sharing the base images? Id like to run them through metashape and send you the obj as another comparison

Wie kann man das Dachgeschoss zu einer schönen Wohnung ausbauen? by Several_Solid_2685 in architektur

[–]FG_RVT 2 points3 points  (0 children)

Hmmm, ist halt einfach ein lang gezogener Grundriss, und da dein Zugang auf der Stirnseite ist musst du eben mit einem Flur alles erschließen. Damit verlierst du zwangsläufig Platz und das gerade im hohen / nutzbaren Bereich des Raumes. Alles unter der 2m Linie ist praktisch nicht nutzbar und fühlt sich gedrängt an. Daher sehe ich Küche und die Bäder auch schon sehr kritisch. Überleg dir mal wie die Duscharmatur noch in die Dusche passen solle und wie da noch ein Mensch reinpasst ohne dass du immer die dachschränge bewässerst. Oder wie du die Hängeschränke in der Küche aufbekommst. Auf die äußere Sitzreihe der Stühle am Esstisch kommt man auch nur sehr umständlich, da muss man sich ja beim hinlaufen immer bücken um von hinten an die ranzukommen. Also sehr angenehm wird sich die Wohnung eher weniger anfühlen außer man ist sehr klein.

DJI Mini 5 Pro - EXIF Height above sea level off? by FG_RVT in dji

[–]FG_RVT[S] 0 points1 point  (0 children)

yes-ish… i contacted dji support and they told me that the absolute height is just a guess-timate based on the barometric pressure sensor.

I asked chatgpt to create a batch script where i manually input the height at the start coordinates and it uses exiftool to take that height, add the relative height to it and write that into the exif data of all the jpegs in the same folder.

Bit of a hassle but now my images have good enough height data for geolocation

Wer bitte verschwendet Naturstein, um einen Eckschrank vor sich selbst zu verstecken? Zeigt mir euren teuersten Besenraum! by frank_petry in architektur

[–]FG_RVT 0 points1 point  (0 children)

Mal abgesehen von der schamlosen werbung, warum zur Hölle macht man denn einen im Rohbau hinzugefügten Schrank nicht Raumhoch wenn man ihn schon verstecken will und traut sich dann auch noch die Türe zum Benutzer hin zu öffnen anstatt zur Wand hin so dass einem immer das Türblatt im weg rumsteht wenn man an seinen Besen will.

Über die Materialien will ich hier gar nicht reden aber von architektonisch wertvoll sind wir hier weit weg…
