I’m a beginner on Ladybug. I have been practising Ladybug by watching all videos on Youtube. But there is a small problem showed up. When I was setting up point for textpoints, the points which were supposed to show up on the Rhino didn’t show up and I thought It’s probably because I didn’t link sunvetors but, after I linked sunvectors to Sunlight Hours Analysis, the programme stopped working. I don’t know how to solve this one. I’m currently using 0.0.62 ver and the lastest one of grasshopper. Thanks for reading
First of all a couple of information about LB components: if you see the inputs, you’ll see some underscores on the right side, left side or both side of the words. Left underscore: you need this to run the component Right underscore: it is optional On the both sides means: you need this but there is a default value inside, so if you don’t connect a data, the component uses the default value as input.
To run LB sunlight hours analysis you need _geometry, _disFromBase, _sunVectors, _runIt.
Coming back to your issue, Have you set a Brep in Grasshopper? When a component or a parameter becomes orange there is a warning for you.
I suggest you also take a look at example files on Hydrashare:
I have set a brep in Grasshopper and linked every needed info(Geometry,gridsize,disfrombase,toggle). However, the problem is when I set a point component to testPts, it doesn’t show up in Rhino model and when I changed Toggle False to True after linking every needed components even sunvectors, Programme stopped working and stuck.
I really appreciate your examples! Then I maybe set up too many breps which was over 40 buildings. I have figured out that if I make small numbers of buildings, It works fine. Thank you very much
Hello Advisors!!
I need help …
I have the exact same problem as above mentioned by @MisungKwon and I am also a new user.
I tried to check my testpoints and the points which were supposed to show up on the Rhino didn’t show up. After I linked sunvectors to Sunlight Hours Analysis, the programme stopped working.
All the dialogue boxes are in normal status (light grey) where I connected and set the grid size (1), geometry (brep), dis fr base (0.1) on the input side. I connected a “point” to “testpt” on the output to preview the test points but I cannot view. I linked a panel to view the test point and it states "0 ".
My rhino model is imported from sketchup file (in millimeters) and I have simplified the model and group them before assigning to brep in GH. I am not sure why I cannot view the testpoints and I cannot run it after I connect sunvectors.
I’m currently using Rhino 6 with latest version of GH, LB and HB. Sorry, I am new so forum doesn’t allow me to upload any files
Hello @Joey_L , as you have used mm as units the grid size you have mentioned is very small for analysis. I recommend to use meters as units ( or in mm but increase grid size like 500mm) and provide a reasonable grid size. And also recheck if all the surfaces for up orientations.
@Asisnath Thank you!! I managed to simulate after I changed my model to meters unit but i still cannot preview my test points… Is there something else I need to set?
How do I check the surfaces for up orientations? Thank you in advance!
@Joey_L i checked your file. The geometries were missing. You had sun vectors missing for analysis. I have modified and reattached the file. 2020-04-29_Option 05_base model.gh (492.6 KB)
