Linking rhino python with web tools for automating offroad maps
@dcantwell wrote:
In Rhino 5, I have manually created some GPS tracks of the Pacific Crest Trail using Halfmiles GPS data files (using a GPX converter from another website) and then manipulating the geometry to get reasonable elevation profiles superimposed on google maps. I like the results but I need some advice. Since I believe there are many GPS track files available for public use, I could envision virtual trips thru many offroad destinations. Think Google earth without the constant need to control the flight. Towards that end, can python be linked with other web tools to exchange data or files between the apps. I manually go to a website enter a filenames and parameters, execute a conversion, then download those files. In python I execute a XPS reader that generates a profile curve. I do the same for extracting a google map image for a pictureframe. Can I automate this ?

Script to incrementally save a file
@Ncik wrote:
G'day Everyone,
Does anyone have a script for saving a file with date and/or time appended to the front? Similar to incremental save functionality it will create a new file each time and/or each day it is run.
regards,
Nick.

Weave lists of pts together
@brobes05 wrote:
I am new to python (sort of), anyway I am not sure why this is not working. Should be simple to weave two lists together with a boolean pattern of true false.
I don't really understand how to flatten the two lists after using python's built in 'zip' function.
import rhinoscriptsyntax as rs list1 = [] list2 = [] list3 = [] for x in range (0,20,2): y = 0 z = 0 ptlist1 = rs.AddPoint(x,y,z) list1.append(ptlist1) for x2 in range (0,20,3): y = 0 z = 0 ptlist2 = rs.AddPoint(x2,y,z) ptlist2move = rs.MoveObjects(ptlist2, (0,5,0)) # rs.DeleteObjects(ptlist2) list2.append(ptlist2move) def weaveLists(): zip(list1, list2) flattenList = [item for sublist in zip(list1, list2) for item in sublist] #this line confuses me list3.append(flattenList) return rs.AddPolyline(list3) # attempting to weave lists together with a boolean pattern like the 'weave' pattern in # grasshopper.

List rotation of an object
@juancarreras wrote:
Is there a way to extract the rotation angle of an object in relation to its original position when it was created ?
Ideally I'd like to be able to display an annotation tag that shows that angle, always in relation to its original angle (zero).
I need only its rotation on the xy plane.
How can this be scripted ?
Thanks

Bug in rhinoscriptsyntax toolbar.py (more or less solved)
@Helvetosaur wrote:
Continuing the discussion from Toggle toolbar visibility without knowing its parent "collection":
Running the following script in my setup errors out on the line indicated:
import rhinoscriptsyntax as rs def ToggleToolbarVisibility(tb_name): for tb_coll in rs.ToolbarCollectionNames(): if rs.IsToolbar(tb_coll,tb_name): #<--Here if rs.IsToolbarVisible(tb_coll,tb_name): rs.HideToolbar(tb_coll,tb_name) else: rs.ShowToolbar(tb_coll,tb_name) break ToggleToolbarVisibility("ToolbarName")The error message is: "expected int, got str"
IsToolbar () is expecting an index for tb_name and not a string.
Edit - Never mind... apparently the example I am using needs the third argument in IsToolbar() to be True. Otherwise, with the default=False it errors out. Still, somehow this should be error tolerant and return None, not blow up... No?

OT, automating Acrobat
@JimCarruthers wrote:
Hi group,
I'm trying to read some form information from PDF files. I'm trying to connect to Acrobat from Python in Rhino, and looking at every example I can Google I seem to be missing something. I'm successfully able to connect to Acrobat Pro XI and open the file and get a reference to it--confirmed by trying out grabbing some basic properties--but long story short I can't figure out how to correctly use the getField method to get a reference to a form field, I can't find the right context in which to call it, neither on the "app" nor the "document" nor the "Javascript object" works. It seems like (if you look up this stuff) the "GetJSObject" step isn't working, it doesn't crash but anything I attempt to call on the object(whether a valid procedure or not) returns the baffling error "Value does not fall within the expected range"
Here's a sample code:
from System import Type, Activator
def main():
TestFile="your-pdf.pdf"
AVDoc=Activator.CreateInstance(Type.GetTypeFromProgID("AcroExch.AVDoc"))
AVDoc.Open(TestFile,"")
ppdoc=AVDoc.GetPDDoc()
jso=ppdoc.GetJSObject()
print jso.getField('ReferenceID').value()if name=="main":
main()Thanks,

Issues Creating Plugin From Python Script
@Steven_Elliott wrote:
I'm trying to compile my python script into a plugin for Rhino 5 but am running into an issue that I am not able to fix. When I run my script in the Rhino editor it runs fine, although when compiled into a plugin (Im using the Rhinoscript Compiler) the script will not run all the way through. It's really tough to debug when I cannot see an error like when I do in the editor.
I've tried putting print commands in the script to see exactly when it is failing and ive sort of narrowed it down to a line or to but still cannot see when the issue is when the script is running just fine in the editor. Here is a snip of the code where I think I am running into the error:
def BuildComponent(MPoints,EPoints,Degree,Components): if Components == 1: Curves = [] for CrossSection in range(len(MPoints)): Curves.append(RS.AddCurve(MPoints[CrossSection])) elif Components == 2: Curves = [] for Count in [0,1]: for CrossSection in range(len(MPoints[Count])): Curves.append(RS.AddCurve(MPoints[Count][CrossSection])) Sections = [RS.AddLoftSrf(Curves,None,None,Degree)]If there was some way to see the errors python is returning in the rhino command window it would help a lot but I'm sure that there is.
I appreciate any help

Quicker Block Select Instances
@benjamin wrote:
My current method for quickly selecting all the instances of a selected block is by bringing up the block manager and then hitting the select button.
Is there a method that could be written which does this quicker? Bringing up the block manager is quite time consuming once the model builds up.
Of course there is SelBlockInstanceNamed but scrolling through the names to remember which one you want is also not ideal.
So the logic would be something like: (Prompt user to select block) ▶ Select all items with reference block ID ▶ return selected Blocks
Would also be good if it could work with multiple selections of block instances
Any ideas?
Cheers

How to convert an RGB color value to grayscale in python inside GH?
