your channel will become school for future architects, youre truly something different

[@DesignGoBrr]

Ah, thank you. That's my hope for the future.

I truly appreciate the high-end content you make. Patreon guy since 2020. I think what originally attracted me to your channel was the advanced content you first started posting like structural optimization for design, and that you throughout your videos de-mystified and explained the way rhino works behind the hood, why you make what choices, and that you were making mistakes on the fly and correcting them, which helps me understand the whole rather than just the parts. I found you once I started applying for architecture school in 2020 and got rejected. Got a job as a technical drafter, and spent freetime learning rhino from your channel, applied again, now halfway done with 2nd year of architecture in Oslo, and wouldn't you know it... The focus is on landscape analysis and map drafting! Thanks again bud. I try to plug you to everyone who wants to learn. Hjertelig takk from Norway!

Oh cool! Really glad to hear that! AHO? I did a year in AHO, living in that high student housing near St.Hansaugen (remember my orange juice freezing in my room during the coldest week in winter + radiaotors bursting) good times good times

It may seem to have a problem while using grashopper in rhino 8, they changed the data types, the text object info doesn't work...

[@yazgidemirbas7008]

This is vital! Thank you!

[@DesignGoBrr]

No problem! :)

[@pareshpatel4596]

Damn ... amazing one....

[@jasonvayanos5615]

It seems that the rotated texts are simply the texts that annotate the contour curves, hence the 50cm increments. If you check the contour curves they should align with them.

[@DesignGoBrr]

Yea, that's true!

Hey Gediminas, great as always. Im trying to use this for my cityplan for uni since there are so many points and only a 2d DWG with textfields for the terrain heights. Way too big plan to do it manually. Unfortunately, I only have Rhino 8 and the Dynamic Geometry Pipeline Output is just empty text entities. I think McNeel changed the way something for the update. Is there a way to get it to work without too much hassle? Greetings

[@JeremyFukunaga]

You never dissappoint, Gediminas! Thank you for creating this video. Unfortunately, I did run into an issue early inthe process with Grasshopper and thought I would ask here in case others experience it. At 10:37, after I hook up the Dynamic Geometry Pipeline, it says that the Output are Referenced empty text entities. Proceeding to the Text Oject Info node, it shows the output as a list of Nulls. I also don't see the same location grids for each text object in the viewport. Any ideas? Thank you.

[@felx4222]

I have the same Issue, did you find a work around for Rhino 8?

[@dwemeri9895]

Very informative video! But how did you manage the dark mode in Rhino? Did you set each color individually, or is there a way to import the colors?

[@DesignGoBrr]

Oh that's Rhino 8 at the start of the video. It has dark mode option

[@mayssayasmina2072]

Hi! How to mâle a mesh as a landscape inside unreal please? An ifvthere any plugin (free) to livelink grasshopper with unreal? Thank you!

[@DesignGoBrr]

Technically there is Rhino.Inside.UE that you could use, but I would suggest just doing a good old fashioned Bake -> Export

I HAVE A QUESTION TO ASK IS there is any way to convert trimmed poly surface to surface for grasshopper project

[@DesignGoBrr]

it really depends on the shape that the trimmed polysurface has - sometimes you can do it by contouring the form in x or y direction, rebuilding the contours to have exactly same number of points and lofting them - but generally speaking - no. Most forms cannot be re-engineered into a single surface without large sacrifice of quality/precision

[@Architect-uzairkhan]

@@DesignGoBrr ok thanks for response i m trying the contouring is working but when you have a hole in the surface then its not

[@DesignGoBrr]

@@Architect-uzairkhan Yup, then you're stuck with a polysurface

[@Architect-uzairkhan]

@@DesignGoBrr thanks anyway

How can we get topography lines from a site? Having them be as accurately possible

[@cgsather3309]

There are several websites that will give you all sort of site data, including contour lines. I’ve used Equator Studio, they also have a free subscription.

[@DesignGoBrr]

As accurate as possible would require a proper site survey. Either by a company, or via drone + photogrammetry. Municipalities and other government agencies sometimes have pretty good data (specially in cities), but those usually require you to e-mail/call them.

[@mhammedmojahid1540]

Thank you teacher please file Dwg

[@rsnmaa]

If you'd use TerrainMesh plugin directly in Rhino, this video would be 1 minute long instead of 48 minutes.

[@DesignGoBrr]

Does the terrain mesh plugin automatically lift survey points according to the nearest text information that's present? Haven't seen that functionality

[@rsnmaa]

I have never received a survey reduced to 2D so my imagination ran short of seeing this as a real situation. But no, it doesn't have such a feature.

[@DesignGoBrr]

@@rsnmaa If a survey is ordered these days, then yea - usually the points are already in the correct altitude. If you're getting one from the municipality archives (which clients get when they purchase the land) - then more often then not your either getting a scanned topo drawing, or a 2D CAD file at best.
