I think the best would be to have a snapshot of your Sketchup Plugins Directory. It looks like there is an old LibFredo6 somewhere.

WARNING: Potential issues in TopoShaper (IsoContour) with LibFredo6 7.7d.

I will publish a fix in LibFredo6 v7.7e as soon as the Extension Ware House site works again.

Greetings,

I am a extreme beginner with SU and am trying to use toposhaper to generate a topo of a piece of land I recently purchased. Reading, researching, and a lot of trial and error!

I am using previous survey data and septic design plans to do this. I have a .txt file with 144 points of xyz data. I imported that into SU with point gadget in a .csv file and have all the points imported. My problem is getting toposhaper to accept the points. I either get a I have tried to install toposhaper with libfredo6_v7.7e prior multiple times with no luck. I could not find the auto-installer and have installed via the extension manager. I'm sure I am screwing something up, just can't pinpoint what I am doing wrong. Any tips are much appreciated. I will continue to search through the libfredo post as well. I have attached my data and some screen shots of the messages I am generating. I see others have had similar issues so I'm sure its some user issue on my end.

I am using SU Make 2017, Windows 7

Thanks,

hiryfi

@hiryfi

From the trace, it seems you have installed LibFredo6, TopoShaper (and FredoTools) correctly. Can you confirm?

For generating a terrain from the point cloud, Toposhaper requires that the points are

Construction point (Guide Point in Sketchup), positioned at their altitude.
all enclosed within a group
If you add one or several faces within the group, they will delimit the boundary of the terrain by projection.

There are tools to import point clouds from CSV or TXT file (one by Didier Bur and one by TIG), I think.

Also, have a look at the videos in the first post of this thread for TopoShaper generation of terrain from point clouds.

@fredo

Thanks for the help, I used a different importer from TIG and yielded much better results. I made a small donation to your paypal on 9/22 for your time and wonderfully narrated videos on TopoShaper.

Cheers,

Thank you for this wonderful plugin. I do have a question about the cell sizes. Is there a way to increase the cell size beyond 200? The current contour profiles that I'm using is set at 2 foot intervals. Unfortunately for the size of the profiles, the 200 limit on cell sizes is producing a less than desirable resolution for the entire map. I will gladly donate as this is an exceptional tool, but could you provide guidance or suggestions on any way to increase the cell size limit. Thank you in advance and kind regards.

NEW RELEASE: TopoShaper v2.3b - 06 Dec 17

This is a minor release with an increase of the grid resolution for the Contour tool

up to 200 by Default
up to 2000, by changing in the Default Parameters dialog box

See main post of this thread for Download.

@slagothoric

The purpose of TopShaper is to smooth the terrain to a grid. so this is why a too detailed grid is usually not necessary. In addition, the algorithm is quite greedy, so oversampling the grid may lead to very long computation times.

Anyway, I just published a new version, TopoShaper (v2.3b), where the default maximum value for the grid resolution an be increased up to 2000, by going to the Default Parameters box of TopoShaper (default is still 200). But be prepared to have a long coffee break...!

You can download the RBZ at https://sketchucation.com/pluginstore?pln=TopoShaper

Note that you need to install also the companion library LibFredo6.

Otherwise, the best is to install the Sketchucation ExtensionStore plugin and then auto-install TopoShaper and any of the 800 plugins in the store in one click.

Hi Fredo,
*) How do I solve 'needle eye' obstacle (see attached)? Plugin get stuck at this stage forever.
*) Second very primitive mesh crashes on generating. Could you take a look at this example?
P.S. I always had scruples to ask, What is purpose of this 2nd 'zoomed' mesh in beige square?

Thanks

Your models seems 'unprepared' for TopoShaper. I don't see contour lines, but instead lot of edges with intersections and different altitudes.

The blocking on Needle Eye is actually just a Ruby error due to the convoluted configuration of contours, but even if I fixed it, I don't see how you can generate a terrain from your input data.

RTFM helped as usual, many thanks

I was wondering if there is a limit to how detailed a ISO lines terrain can be to work with Toposhaper?
As you can see in the attached image only a part of the terrain is created. If I try with a less dense contour file of the same area it works but I need the detail as high as possible.

The typical usage of TopoShaper is to smooth out the terrain, using isocontours as guides for altitude. The precision of the contours is not necessary (i.e. does not need closely spaced contours, nor many points in the contour curves), and anyway in relation with the resolution of the mesh.

All this being said, I am impressed by the large model you have.

Bonjour Fredo,

Après installation de la dernière version de Toposhaper (2.3b) et de LibFredo6 v8.1h, Toposhaper ne s'execute pas à l'ouverture de Sketchup, renvoyant un message d'erreur qui est le suivant : "you must install LibFredo6 to run Toposhaper
Open the download page of LibFredo6 at https....".

Après vérification dans l'extension manager, LibFredo est pourtant bien installé. Une idée sur l'origine du bug ?

Il faut verifier que LibFredo6 est bien chargé. Est ce qu'il y a un menu Window > LibFredo6 Settings.... ?
