  1. Hello Vlado Many thanks again, I appreciate very much your considerations.
  2. Hello Vlado Thank you very much for your response. That clarifies what I was assuming – but hopped it is not the case. But it is the reason why in VW python "sys.excecutable" on the MacOS/darwin plattform is pointing to the VW app, and why "pyhton" and "pip" are not exectuable on the command line inside the darwin VW app package/bundle (error : missing python image). It would makes only sens to install an additional python installation inside the VW app/bundle, if this will replace the internal VW python environment to run the scripts. But after some days finally I was able to install 3.5.2 and get it run as standard installation on the MacOS . This 3.5.2 standard system installation is only used to get the rigth modules (like geopandas and some related modules) installed an be used in VW (installed on '~/Library/Application Support/VectorWorks/2020/Python Externals'). But I have also to say that python 3.5.2 is for lot of modules a critical version. Python 3.5.3 is much less critical - but module versions loaded with 3.5.3, were incompatible with 3.5.2. Thus I would very appreciate, if in VectorWorks a more recent version of python would be embedded - at least the latest version of an allready EOL minor version - for python 3.5 > 3.5.9. But meanwhile python 3.7 is very common, not pointing to python 3.8. Many thanks again and best regards, relume
  3. Hello JBenghiat Thank you very much for your message. Yes I had allready carried out the same steps as your hints, prior to post the topic. Finally I could resolve the problem with the 3.5.2 installer that was broken for a outdated SSL certificate (with pip it was not possible any more to get the python "pypi.python.org" cache for looking about python packages. Neither it was possible to update PIP for the same reason. Updating PIP resolved the problem: curl https://bootstrap.pypa.io/get-pip.py | python3.5 where python3.5 is the python version installed from 3.5.2 best regards, relume
  4. VectorWorks : v2020 SP2 MacOSX : 10.14.6 Hello I am facing big troubles to install some modules like "geopandas" to use them with VectorWorks 2020. Actually I can install with an external python installation version 3.5.9 (the latest version in 3.5) all needed modules. Unfortunately there are some incompatibilities (for example for "pandas") while importing against the the internal VectorWorks 2020 python version 3.5.2 and its built-in functions. So I installed a python 3.5.2 version from the official download page, but now it is not possible to locate any external module, that satisfy the requirements of version 3.5.2 and further I am getting errors that says: 1 location(s) to search for versions of rtree: * https://pypi.python.org/simple/rtree/ Getting page https://pypi.python.org/simple/rtree/ Looking up "https://pypi.python.org/simple/rtree/" in the cache Returning cached "301 Moved Permanently" response (ignoring date and etag information) Looking up "https://pypi.org/simple/rtree/" in the cache Cache entry deserialization failed, entry ignored Starting new HTTPS connection (1): pypi.org Could not fetch URL https://pypi.python.org/simple/rtree/: There was a problem confirming the ssl certificate: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c: It seems that VW 2020 python version 3.5.2 is really outdated and thus it would be "best" to update the internal VW version to 3.5.9 at least. Is this feasible and how? Many thanks, relume
  5. Hello I have posted some (final) findings on the other topic pil-python-image-library-for-vw-2018. As for the problem with the before mentioned "pyspatial" module the problem is inherent to the actual version of the "pyspatial" module and the pip version that module is installed with. Other modules that use setup.py "e.g. rtree" can be installed with above (final) findings without any problems.
  6. Hello Patrick I am sorry to respond only today to your posting. Many thanks for posting the "Marionette.VerifyOrGetLib()" implementation. I previously searched in vain for the Marionette lib/package inside the VectorWorks 2020.app package (MacOS version). Where did you found the Marionette.py file? It is remarkable, that they use for the installation of modules for the MacOS/darwin plattform not the python distro that is installed inside the VectorWorks 2020.app package but the standard python installation : sys.executable = '/usr/bin/python' ret_code = pip.main(['install', destination,'-q','--target', cmd]) sys.executable = sys_executable_orig On my MacOSX 10.14.6 system "/usr/bin/python" shows version 2.7.16. VectorWorks 2020 has installed version 3.5.2. Furthermore now it became clear to me why installing the modul by pip with an subproccess call and using the value of "sys.executable" did not work and opened a new instance of VectorWorks 2020.app. On the MacOS/darwin plattform "sys.executable" does not hold the path of the internal python installation but the VectorWorks 2020.app itself: /Applications/Vectorworks 2020/Vectorworks 2020.app/Contents/MacOS/Vectorworks For that reason I tried to call directly the internal (VectorWorks 2020.app) python installation to work with it and to have the corresponding python version for installing appropriate modules. But it seems that the internal python installation is not callable and executable: dyld: Library not loaded: /Library/Frameworks/Python.framework/Versions/3.5/Python Referenced from: /Applications/Vectorworks 2020/Vectorworks 2020.app/Contents/Frameworks/Python.framework/Versions/3.5/bin/python3.5-32 Reason: image not found The call by "subprocess.run('...../bin/python3.5-32', '--version') results for all python bins to "image not found". So I have to assume that for VectorWorks 2020 on the MacOS/darwin plattform the internal python installation and thus the pyhton image (binary) is somewhat "hiden" or maybe compiled into a VectorWorks package (?). For that reason I installed finally for MacOS/darwin with homebrew an appropriate python 3.5.X installation which is then linked and callable to: /usr/local/bin/python3.5 or /usr/local/bin/pip3.5 thus now I have modified my own modul installation function in order also to use on the MacOS/darwin plattform the now standard subprocess function "subprocess.run" that replace all other previous subprocess functions: vVW_AppUserPy_folder = vs.GetFolderPath(12).replace(':','/') + 'Python Externals' vPython_path = '/usr/local/bin/' vPython_pip_path = vPython_path + 'pip3.5' vModule_version = '>=2.5.0' # vModule_version can be passed to pip directly behind the module name vModule_version = '' vCommand = [vPython_pip_path , 'install', '--upgrade', '-v', vModule+vModule_version, '--target', vVW_AppUserPy_folder] vPip_proc = subprocess.run(vCommand, stdout=subprocess.PIPE, stderr=subprocess.PIPE) vPip_proc_exit_code = vPip_proc.returncode vPip_proc_sdtout = vPip_proc.stdout.decode('utf-8') vPip_proc_sdterr = vPip_proc.stderr.decode('utf-8') best regards

Many thanks for any hint, relume P.S. the Marionette.VerifyOrGetLib() approach does not work really, if you do want to install libs/modules in more generalistic way like this e.g. "pip.main(install --upgrade 'dateutil>=2.5.0' and without passing the ressource URL as it is needed in Marionette.VerifyOrGetLib()
  8. Hello I am wondering if there is any documentation for the Marionette function "Marionette.VerifyOrGetLib()" with its posssible parameters. I am wondering if it is possible to get an lib/module and a specific Version with "Marionette.VerifyOrGetLib()" as with pip (e.g. pip.main('install', '--upgrade', 'dateutil>=2.5.0') thus not passing a specific ressource URL? I have the problem that for some python lib/modules (e.g. pyspatial or rtree) the pip.main() approach does not work, as on installing those libs/moduls a setup.py call is started an therefore a new instance of VectorWorks.app is started. see my other topic (installing-modules-from-within-a-script) : I am sorry for crosspointing. Many thanks, relume
  9. approachVectorWorks : v2020 MacOSX : 10.14.6 Hello I have used until now sucessfully the following code snippet to install missing modules: see also this forum entry: "PIL python image library for vw 2018" vModule = 'mymoduleToimport' pip.main(['install', '--upgrade', '-v', vModule]) # or vVW_AppUserPy_folder = '/Users/myuser/Library/Application\ Support/VectorWorks/2020/PythonExternals' pip.main(['install', '--upgrade', '-v', vModule, '--target', vVW_AppUserPy_folder]) This works for most modules. For some modules (e.g. pyspatial) this approach is not working and instead a second instance of the VectorWorks.app is started without any error (only verbose console output), but those modules are finally not installed. As far as I can see, those modules that are not working are calling the setup.py script. Is there any way to suppress this behavior? While "debugging" I learned, that in PIP > version 10 (actual PIP version is version 20, and in VectorWorks v2020 version 8.1 is installed by default), the pip.main() function is removed and the following construct should be used: vPip_proc = subprocess.run([sys.executable, '-m', 'pip', 'install', '--upgrade', '-v', vModule, '--target', vVW_AppUserPy_folder ]) vPip_proc_exit_code = vPip_proc.returncode vPip_proc_sdtout = vPip_proc.stdout vPip_proc_sdterr = vPip_proc.stderr Unfortunately this approach is not working at all for all python modules. Every time a second instance of the VectorWorks.app is started without any error and output and no module is installed. I would appreciate any hint or suggestion how to solve this problem. Many thanks in advance, relume
  10. @MullinRJ Many thanks four your hint! It seems that I did not seek the VS functions in deep 🙄. The vs.ConvertToPolygon(h, resolution) is perfect. relume
  11. Hello For external geometrical processing in a python script, every VW polygon that has one or more curved vertices has to be converted to an approximated "lines only" polygon. This represents the standard transformation for any curved vortex on exporting VW objects by the export function to the Shape-Geodata format. There is also an VW-menu functionality, that converts a polygon to a multi-line group, where curved vertices were approximated by as many needed short lines. At the moment I can not see, how I can get/convert to such a "lines only" polygon by a VS function. The idea is the following: get the handle of the VW polygon. test if there is one or more curved vertices by looping through all vertices of the polygon (using vs.GetPolylineVertex). if there is any curved vertex in the referenced polygon, make a temporal copy of the original polygon and convert this copy to a "lines only" polygon. process the "lines only" polygon as needed in the python script Step 3. is the operation I am interessted in – a "fast" and VW internal converting operation to a "lines only" polygon or a group of lines. Many thanks in advance for any hint, best regards, relume
  12. Hello I am not sure, if have understood correctly your question. However I can say the following: the progress dialog can be displayed without the vs.ProgressDlgStart() and terminated without the vs.ProgressDlgEnd() call. without calling vs.ProgressDlgClose() the dialog window stays open until the script terminates. vs.ProgressYield() has to have a numeric parameter vs.ProgressYield(1), otherwise pyhton errors are thrown. vs.ProgressYield(int) has to be called otherwise the other messages like vs.ProgressDlgSetMeter(message) are not refreshed on the dialog window. def messagePtest3(): selCount = 10 def DoTheWork(): # vs.ProgressDlgStart(100,selCount) for i in range(selCount+1): vs.ProgressDlgYield(1) vs.ProgressDlgSetMeter(str(i)) vs.Wait( 1 ) #well, we work by waiting vs.ProgressDlgOpen( "I'm about to do some work", False ) vs.ProgressDlgSetMeter("") # this resets previous values, if vs.ProgressDlgStart is not callded DoTheWork() # vs.ProgressDlgEnd() # vs.ProgressDlgClose() # if close is not called, the dialog stays open until the script terminates best regards, relume
  13. Hello Many thanks for your ready "receipe", I appreciate that very much. I hope the dataframe populating process with every single polygon vortex will not be slowed down by the VW functions calls - but it is the only way to do it. best regards

  15. Hello For certain reasons I am "misusing" VectorWorks for some GIS related tasks. So I have to find for a hugh number of simple 2D polygons all possible 2D points on a certain layer that are inside each polygon - the so called "point in polygon" or "PIP" problem. My VectorWork python script using the "vs.FindObjAtPt..." functions is good for a small number of polygons and points but frustrating slow for a large number of objects to be matched/tested – I am siting in front of the computer screen now for more than 72 hours, waiting and without any hope and no idea (for that fact that the vs.message fuctions still does not work in VW2020) when the script will terminate. So my idea is to "outsource" the hole PIP processing to adequate python modules like Geopandas, where solving diverse PIP problems are representing standard functions. Thus has someone already some experience or best practice how to "poke out" (transfer) most efficiently and fast the geometric VW object data inside of a VW pyhton script to a Geopandas data structure (data frame) in the form of e.g. for a polygon (x0 y0, x1 y1, x2 y2, ... , xn yn). The question is related to VW given functions to access the object geometric informations hopefully a single step (function call)? Many thanks in advance for any hint and best regards, relume
  16. Hello The message command issue has still not been fixed in VW 2020. best regards, relume

  18. Hello With VW2019 I came across, that in my example file "viewport.vwx" the Python-Script "with visibility" to generate a ViewPort and to assign to it the layer visibility to active will crash VW2019. If the created ViewPort is manually deleted VW2019 will crash. So in the loop to assign the layer's visibility to active a condition has to assure, that the visibility is only set to design layers (many thanks to D. Corpataux from ComputerWorks.ch). So in the attachment there is a new stable Script named "with viability stable VW2019". best regards viewport_v2.vwx # python-script : "with visbility stable VW2019" import vs def createviewport(ModuleLayer, objectHandle): vs.Layer(ModuleLayer) # make sure we are on the correct starting layer # screenName = objectList[selectedObjects][0] # Gets the Screen Name - 1st item in t = (screenName,objectHandle) # objectHandle = objectList[selectedObjects][1] # Gets the Object Handle - 2nd item in t = (screenName,objectHandle) # Get the object height, width and bounding box of object p1, p2 = vs.GetBBox(objectHandle) objectWidth = vs.HWidth(objectHandle) objectHeight = vs.HHeight(objectHandle) #Create VP Crop Object vs.Rect(p1, p2, objectWidth, objectHeight) vpCrop = vs.LNewObj() # Create the layer and set the layer name layerHandle = vs.CreateLayer('01', 2) # using 01 forces the next unused sheet nubmer to be used layerName = vs.GetLName(layerHandle) # get they layer name. It appears the layer name is the sheet number #vs.SetObjectVariableString(layerHandle, 159,'Module Layout - ' + screenName) vs.SetObjectVariableString(layerHandle, 159,'Module Layout - ' ) # vs.Rect(0,0,10,10) # test to see if something draws on the sheet layer #Create the VP and set Crop Object vpHandle = vs.CreateVP(layerHandle) vs.SetVPCropObject(vpHandle, vpCrop) vs.SetObjectVariableReal(vpHandle, 1003, 32) #set scale to a default of 32 ## set class and layer visibility to viewport object vClassNum = vs.ClassNum() for vClassNumIndex in range(1, vClassNum+1): vs.SetVPClassVisibility(vpHandle, vs.ClassList(vClassNumIndex), 0) vLayer_handle = vs.FLayer() while vLayer_handle != None: vLayer_Type = vs.GetObjectVariableInt(vLayer_handle, 154) #Design Layer or Sheet Layer if vLayer_Type == 1: # Design Layer vs.SetVPLayerVisibility(vpHandle, vLayer_handle, 0) vLayer_handle = vs.NextLayer(vLayer_handle) viewPort_X, viewPort_Y = vs.HCenter(vpHandle) print(viewPort_X, " ", viewPort_Y) ModuleLayer = "test" vs.DSelectAll() vs.SelectObj("(ALL)") vs.Group() vGroup_handle = vs.LSActLayer() createviewport(ModuleLayer, vGroup_handle) vs.HUngroup(vGroup_handle)
  19. Hello Thank very much you for your hints and considering my questions. The command vs.CallTool() is not applicable, because I have to use an allready existent polygon as selection perimeter and do not want any user inteaction. Iterating over every point to check by vs.PtInPoly if it is on/witin the actual polygon is some kind of "brute force", as I have to iterated first over every polygon an then itereate over all points to be checked for each polygon. But it seems that there is no other approach to do it. I wondered if there would be any VW criteria to select objects by a x/y range (select all objects where x/y is >= as xTop/yTop AND x/y is <= xBottom/yBottom) in order to optimise somebit the iteration process by reducing the amount of relevant points to check after in detail if they are within a certain polygon. But unfortunately such numerical/grafical criteria search is not available in VW as it is part of every GIS-tool. By looking again at the VW search criterias I found the "location" critearia. If an object has a given name, it is possible to formulate a search criteria that looks for points/objects that are within the object with the given name: import vs vs.DSelectAll() vs.SelectObj("(INSYMBOL & INOBJECT & (L='LayerToSearchIn') & (LOC='MySelectionPolygon'))"); With this search criteria the solution is much easier (I do not know the details about performance differences) but of course for every polygone to test a name (a temporary unique name) has to be given: import vs def searchPoints_for_MyPolygon(vMyPolygon_handle): # the original name of the object to be processed has to be retrieved vMyPolygon_Name_org = vs.GetName(vMyPolygon_handle) vMyPolygon_Name_temp = 'MyPolygon_temp_unique_name' vs.SetName(vMyPolygon_handle, vMyPolygon_Name_temp) # a temp. unique name has to be given for the case the name = "" for correct selection vSelectionCriteria_Points = "(INSYMBOL & INOBJECT & (L='LayerToSearchIn') & (LOC='"+vMyPolygon_Name_temp+"'))" vPointsFound = vs.Count(vSelectionCriteria_Points) vs.SelectObj(vSelectionCriteria_Points) vs.AlrtDialog("Points found: " + str(vPointsFound)) vs.SetName(vMyPolygon_handle, vMyPolygon_Name_org) # the original object name has to be reassigned vs.DSelectAll() vSelectionCriteria_MyPolygons = "INSYMBOL & INOBJECT & (L='LayerWithMyPolygons')" vs.ForEachObject(searchPoints_for_MyPolygon,vSelectionCriteria_MyPolygons) vs.AlrtDialog('finished') best regards, relume
  20. Hello I am back 😐 to the recurrent problem of finding/selecting points or other 2D objects within an other 2D polygon or polyline. As long the number of points to be selected are small or smaller than the number of the "selecting" 2D polygons, then I can iterate over every point to check if it is inside a "selecting" 2D polygon by "vs.FindObjAtPt_GetObj". But if I have a (very) large number of points and a smaller number of "selecting" 2D polygons the above approach is inappropriate, due to the huge iteration over every point. So I thought I would be possible to use/adopt the polygon selection tool to "embrace" the relevant points (to be found) by a 2D polygon. But actually I can not see any way how to script this – how to get by scripting a given 2D polygon in to the polygon selection tool to "embrace" the relevant points. I would appreciate any idea how to get the problem solved, many thanks in advance, relume
  21. Hello I am using my script for producing many small plats in a batch (moving window on every object) to export each to its own pdf for many years - first in VectorScript and now ported to Python. It works without problems. I do not need to ResetObject() nor ReDrawAll(). In general I do not see any greate difference to your code. The only difference in my script is, that I am using a predefined presentation layer and reusing it for every plat to be drawn and exported. But I do not think that this is the problem. I tried and slightly adapted your code (see attachment) and the only proble that I can see is, that vs.CreateVP() creates a ViewPort-Object with no layer and class activation (they are all set to invisible). So running your code I get also this square with the red cross in it. But when I assign class and layer visibility to active for this ViewPort-Object the bounding box of the viewport change to its real dimensions and location. Thus assigning class and layer visibility is "indispensable" to get the correct result, although the square with the red cross seems to be a temporarily "artifact" with a viewport with all classes and layers set to invisible. Finally the new created viewport has to moved to the page center (or any position) - that is default and is corresponding the manual viewport creation. best regards viewport.vwx
