ariations, but each seems to lack the sophistication to generate a ‘zip’ that retains its general shape over the whole curve.
Basically I’m trying to understand the process behind this: http://www.schindlersalmeron.com/index.php?option=com_content&task=view&id=27&Itemid=29
Here is an image of the latest definition.
1. I draw a curve in Rhino, and then define it in grasshopper. I also define the point as the beginning of the curve.
2. I offset the curve to a specified depth, based on structural member
3. I generate a line from the point at a tangent to the curve, then rotate it a
defined angle.
4. I find the intersection between the rotated line and the offset curve. Then generate a tangential line from this new point
5. Line is rotated at the same angle as before.
6. Process repeated.
The idea is to then generate a circle of defined diameter at each of the intersection points, then find the intersection of the circles with the curves, which are then joined up with straight lines to create the ‘zip’. This would mean a lot of copy-pasting and list management that I’m not really capable of with my limited grasshopper experience.
I had tried generating points at intervals along the curve and then eventually generating lines from one line to another with a shifted listed to form the tooth angle, but it wouldn’t retain its shape over the entirety of the curve.
Does anyone have any advice for how to tighten up this definition? I imagine that I will need to delve into vb.net scripting to address the recursive nature of the process.
I fear that I’m going about this in entirely the wrong way...
Of course the next step is to flatten out the curve for CNC manufacture.
Any help would be greatly appreciated! The potential for using grasshopper in design is amazing, and I would love to gain a deeper understanding of it!…

it seems that was this. Now all is working fine !
Glad that it worked! But I am still a bit worried. Gismo components only modify the gdal-data/osmconf.ini file and no other MapWinGIS file. So your MapWinGIS installation files should not be compromised. The fact that you did not get the "COM CLSID" error message when running the "Gismo Gismo" component suggests that MapWinGIS has been properly installed. So I wonder if the cause for the permanent "invalid shapes" warning has again something with the fact that your system is again not allowing the MapWinGIS to properly edit the osmconf.ini. Maybe this problem will appear again, and again, and reinstallation of MapWinGIS every time can be somewhat bothersome.
- About the terrain generation, is it possible to have the texture from google or other provider mapped onto the terrain surface from gismo component ? (Same as using the ladybug terrain generator in fact). I try to used the image extracted by ladybug component and then applied it to the gismo terrain but the texture is rotated by 90°.
The issue with the rotation can be solved by swapping/reversing the U,V directions of the terrain surface. A slightly more important issue is that terrain surface generated with Gismo "Terrain Generator" component might have a bit smaller radius than what the radius_ input required. This stems from the fact that the terrain data first needs to be downloaded in geographic coordinate system, and then projected. Some projecting issues may occur at the very edges of the projected terrain, so I had to slightly cut out the very edges of the terrain which results in the actual terrain diameters being slightly shorted in both directions. This means that if you apply the same satellite image from Ladybug "Terrain Generator" component to Gismo "Terrain Generator" component the results may not be the same.I attached below a python component which tries to solve this issue by extending the edges of Gismo "Terrain Generator" terrain, and then cutting them with the cuboid of the exact dimensions as the radius_ input. Have in mind that this extension of the original terrain at its edges is not a correct representation of the actual terrain in that location. But rather just an extension of the isoparameteric curve of the terrain surface. So basically: some 0 to 10% (0 to 10 percent of the width and length) of the terrain around all four edges is not the actual terrain for that location, but rather just its extension.The python component is located at the very right of the definition attached below.
Also, if you would like to use the satellite images from Ladybug "Terrain Generator" component along with "OSM shapes", sometimes you may find slight differences in position of the shapes. This is due to openstreetmap data not being based on Google Maps (that's what Ladybug "Terrain Generator" component is using), but rather on Bing, MapQuest and a few others.
- About the requiredKeys_ input of OSM shapes, I understand what you mean and your advice, but in most cases I use it, the component was working fine even without input. I think it's better to extract all tags, values and keys of the selected area, instead of searching for specific ones as I try to find all data related to what I want after, isn't it ? To check what keys are present on the area also.
Ineed, you are correct.I though you were trying to only create a terrain, 3d buildings and maybe find some school or similar 3d building, for these two locations. The recommendation I mentioned previously is due to shapefiles having a limit (2044) to how many keys it can contain. This requires further testing of some big cities locations with maybe larger radii, which I haven't performed due to my poor PC configuration. But in theory, I imagine that it may happen that a downloaded .osm file may have more than 2044 keys. In that case shapefile will only record 2044 of them, and disregard the others. That was my point.But again 2044 is a lot of keys, and I haven't been checking much this in practice. For example, when I set the radius_ to 1000 meters, and use your "3 Rue de Bretonvilliers Paris" location I get around 350 something keys, which is way below the 2044.Another reason why one should use the requiredKeys_ input is to make the Gismo OSM components run quicker: for example, the upper mentioned 350 something keys will result in 350 values for each branch of the "OSM shapes" component's "values" output.Which means if you have 10 000 shapes, the "OSM shapes" component will have 10 000 branches with 350 items on each branch (values). This can make all Gismo OSM components very heavy, and significantly elongate the calculation process.With requiredKeys_ input you may end up with only a couple of tens of items per each branch.Sorry for the long reply.…

hat since we create a list of materials and we assign them to surfaces - volumes the next step could be to have an Life Cycle Analysis and Financial assessment produced.
The most common form to produce an LCA into a form that is commonly used and easily communicated is in the form of Environmental Product Declarations (EPDs) that follow ISO 14025:2006. As every form of LCA, EPDs raise a bunch of question regarding their boundaries and the accuracy of the results especially if we include the factor of location. In comparison with other LCA practices though, EPDs have to be followed by Product Category Rules (defining the boundaries of the study) that can be reviewed by external parties if the EPD is to go public. Part from that EPD results reflect each stage of the life cycle of a product including potential benefits from Reuse or Recycling. Finally if you have a system - for example a building - you can add the EPDs of the different subcomponents forming the building and get a final EPD for the building itself - the point where I think HB's functionality is fully aligned.
The financial assessment can easily be concluded if one has the price of the material he/she uses. Finally the environmental indicators of the EPDs (LCI, LCIA) can be translated into Shadow Costs (Shadow costs for Environmental Indicators here) and added to the final financial assessment as an option.
I have developed a similar plug-in (in C#) for Grasshopper for my master's thesis last year. The project focused on the comparison between constructing normally and constructing implementing Design for Deconstruction practices in steel buildings. The idea was to compare the two cases based on their environmental and financial performance. In the process I included also options for transportation of the material and for shadow cost, embodied energy and carbon assessment and more. The final outcome can be visualised in Rhino's viewports and exported to excel sheets. The plug-in is connected to local db with EPD data for steel profiles. The same scheme though can be followed for any type of material if we have the right database to connect it to!
Please have a look if interested at the report here! And let me know if you have any questions!
Please note that the report includes 3+ chapters dedicated to design for deconstruction practices e.t.c that are irrelevant with the topic but maybe interesting to read:)
Also if someone is interested in the report I can always send it to you.
(I will upload a video -runthrough of the plug-in later this week)
I would be very interested to have these capabilities in LB and HB and happy to help realising it!
Thanks

complicated than it seems as I have an event and a subscriber method receiving data from a serial port.
In the code below, the strings received within myReceivedLines appear when connecting with the serial port (when connecttodevice is true). However they disapear when I launch another command (when homeallis true).
As you recommended in your reply, I have added the field called myReceivedLineswithin the class so that I could use the method String.Add() to all the feedback received and commands sent.
Why does the feedback dispear when a command is sent? Is the string going to myReceivedLine disappearing because they happen within a subscriber method or is it related to the DA.SetDataList() method used to assign myReceivedLinesto the output?
Many thanks!
