Thank you. I believe there is some algorithm that do this calculus, because the “Analyse” tool work.

I need to find the intersection of a set of NURBS curves, basically obtained from the "Contour" tool from a mesh surface. By hand, I can select the "Analyze" tool and then click on the two curves and get a 3D Locus on the intersection. How can I obtain the same result using a script? I tried to select the two nurbs and then calling the tool, but obviously "Analyze" wait for the clicks... There is a way to automate this? Thank you roberto

Was the script you posted in my thread “insert values referred to Working Plane in a Worksheet” I am under the impression that if you send a .vwx file containing the script the separators are always correct.

In synthesis, we have to use homogeneous coordinates, in the form [X,Y,Z,H] and a transformation matrix 4x4. The product of the matrices give us the transformed coordinate. The 4x4 matrix is subdivided in zone: [ | 3 ] [ 3x3 | x ] [_______ |_1_ ] [ 1x3 | 1x1] where the 3x3 produce linear transformation in the form of scaling, shearing and rotation; the 3x1 produce perspective transformation; the 1x3 produce translation; the 1x1 produce overall scaling. The singular is that we can have this value instantly transformed simply by clicking on working plane icon in the Object Info palette, but we are unable to tabulate such values...

Hi Pat, thank you! The transformation involves a matrix multiplication, and I am now searching for matrix operation in VectorScript, but I don't remember to have seen such routines. I attach some pages from Mathematical Elements for Computer Graphics (it was my Bible in the early '70!) about 3D transformation. The full book is available on internet: https://tinyurl.com/vfbsl9r Perhaps it will be better to switch to Python, with the large math libraries available for the language. I attach also a drawing with some grid and loci on it (pannello 37) and a general view of the construction. Roberto p.s. to have working the call, I had to change comma to semicolon: =RunScript(WPCoordinate; 'Name of WP'; 'X') pannello 37.vwx lobby panel mesh.vwx Mathematical Elements for Computer Graphics By David Rogers (upestech.com) (trascinato).pdf

Thank you, Pat. I belive that you routine work when the working plane is parallel to the ground plane; I have to take in account also the rotation and so transform the coordinate of the 3D locus. I am now out; when back I'll elaborate more on this. Roberto

Hi I have a mesh, freely oriented in the space. I set a working plane in the needed orientation, then I Create Contours parallels to the X and Y axis on the mesh, obtaining NURBS curves. Then with Analysis menu I place a 3D Locus at each crossing point of X and Y contours, naming it and in an orderly way. At this point I would populate a Spreadsheet with the coordinates of each 3D Loci. I can observe that on Object Info palette, clicking on WP (purple WP icon) I get coordinates referred to the working plane. Now, if I create a database in a Worksheet row inserting the name, X, Y, Z I get always the Active WP (blue icon) coords. So, the question is: there is a way to tell to the formula inserted in Worksheet that I wish refer to the WP? Or I have to transform the coordinates to the WP Origin and Rotation? I attach an image of the Worksheet, the drawing and info palette showing the different values. Any help will be appreciated. Roberto Schermata 2020-01-10 alle 12.54.46.pdf

Ok! THANK YOU!!! I now understand how to do! THANK YOU THANK YOU THANK YOU!!!

Hi Jos, I don't understand your post. I need to create a Text Along Path using Vectorscript, but I don't found a call nor a menu chunk to insert in DoMenuTextByName(...

I need to use Text Along Path in a script. Anyone has an example on how to do? I was'n able to call DoMenuText... Thank you ciao roberto

Hi Alan, thank you. I understand the way I can proceed and now try to adapt the to the full process.

Hi, Pat, thank you. Actually I select all and Intersect, having selected all the small circles and part of it and transfer the selection on a new layer. Your look better, and I missed the Criteria "Location is within".

I have a rectangular matrix of circles (but it can be also an irregular group of circle), a larger circle and the necessity to count the small circle inside the larger. This is a component of a workflow where I have to select a given number of small circle, extrude them and subtract from another solid. Actually I draw the matrix, draw a circle of surface calculated multiplying the area of the square which contain any small circle by the number of circles, retrace the circle with the Polygon Marquee Mode and read the number in the Object Info Pallette, modify the radius of the big circle and so on. The most time consuming operation is tracing, so if I can automate the count of object inside I will be very happy! I attach a demo file with the matrix and a circle, in VW 2017 format. Thank you to anyone can help me. Roberto test selezione inside.vwx

Hi Marissa, I am using the English version of Vectorworks on an Italian language system. I made this test: 1) created a new user; 2) launch VW, inserting the serial, ecc.; 3) running VoronoiObj_v2017_CrossPlatform_MFarrell; 4) I was asked to authorize the download of numpy and later of scipy, I allowed; 5) the Marionette script ran as expected; 6) I checked that a Python External folder was created and populated in User Folder; I found also a copule of other files, as from you screenshot; 7) I copied the folder and files on user folder of my usual user, assigned ownership to myself; 8) running VoronoiObj_v2017_CrossPlatform_MFarrell gave me the usual error of privileges. I also tried to create an empty Python External as from your suggestion but continued to receive the error. Thank you Ciao Roberto

Hi Marissa I don't have "Python Externals" in user folder, nor in the root or in the Library. I created a "PythonExternals" inside Library inside Vectorworks application folder as from some instruction I got on the list. Now I created some "Python Externals" in some locations: but I continue to receive the error of lacking permission (see attached screenshot) and none of Python Externals folders get populated. My service pack is SP3 build 356720. Schermata 2017-03-24 alle 15.59.21.PDF

I am on OS X 10.11.6 and VW 2017 build 356720

Hi Marissa, I deleted numpy and scipy from PythonExternal (I have a copy in Python directory) and get the error in the attached image: I am not able to remove numpy and scipy from /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python (sudo rm -R numpy*: operation not permitted…) Any clue? grazie Roberto Schermata 2017-03-23 alle 15.16.51.PDF

Hi, I am trying to install numpy and scipy without success. I am able to install - using pip - a previous version of either numpy and scipy but I am not able to see them. I placed numpy and the info file and the same for scipy into PythonExternal in Library inside Vectorworks folder, but modifying the voronoi example bring up a - very large - error window. So, I need a better instruction on installing the requested version of the package. Thank you Roberto
