Find All T-Splines by text command or python

Anonymous — Mon, 15 Feb 2021 08:33:39 GMT

Hello

I am sure this is an easy question but I searched all day for a solution. I am writing a script to automate some modification on 3D models before CAM.

In design, Some 3d meshes ( with .obj extension) are imported and converted to "Quad to T-spline". I can do that with this script.

import adsk.core, adsk.fusion, adsk.cam, traceback import os ui = None app = adsk.core.Application.get() ui = app.userInterface def run(context): try: string = ui.inputBox("Directory","File link") ui.messageBox(string[0]) design = adsk.fusion.Design.cast(app.activeProduct) design.designType = adsk.fusion.DesignTypes.ParametricDesignType #Import Meshes file_list = os.listdir(string[0]) for obj in file_list: file_url = os.path.join(string[0], obj) design.rootComponent.meshBodies.add(file_url, adsk.fusion.MeshUnits.MillimeterMeshUnit) design.designType = adsk.fusion.DesignTypes.DirectDesignType #Change Names of Meshes and Create T-Spline from them array = design.rootComponent.meshBodies for component in array: component.name = ' '.join([str(elem) for elem in component.name.split(' ')[4:]]) ui.activeSelections.clear() ui.activeSelections.add(component) #Create T-Spline for each model app.executeTextCommand("Commands.Start TSpline2BRepCommand") x = app.executeTextCommand("NuCommands.CommitCmd") # At this point, I added a screenshot of the browser # For now, I need to do these # 1) Changing name of T-Spline with component.name # 2) Add thicken feature to Mesh with 0.1 mm except: if ui: ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

My problem is that I can not iterate the T-Spline objects. If I can get the T-spline which is created with textcommand above. I can change its name and add a thichen modification.

Best Regards

Hi @Anonymous .

Could you please attach a couple of OBJ files?
The error occurs in an unrelated area and it is difficult to reproduce the situation.

Hi kandennti

Thank you for your help. I attached the sample folder.

1) Exporting zip file to someplace

2) When you run the script, copy- and paste the directory of the folder into the input box.

C:\Users\xxxx\Downloads\xxxx\sample

The script is working on windows system but I think it also works on Linux or Mac because of python libraries.

Best Regards

@Anonymous .

I couldn't find a way to access the TSplineBody, so I went into Parametric Design to edit the FormFeatur and converted it.

After that, I think I can add the thickness of the surface.

import adsk.core, adsk.fusion, adsk.cam, traceback import os ui = None app = adsk.core.Application.get() ui = app.userInterface def run(context): try: # string = ui.inputBox("Directory","File link") # ui.messageBox(string[0]) string = [r'C:\Temp'] design = adsk.fusion.Design.cast(app.activeProduct) design.designType = adsk.fusion.DesignTypes.ParametricDesignType #Import Meshes file_list = os.listdir(string[0]) for obj in file_list: file_url = os.path.join(string[0], obj) design.rootComponent.meshBodies.add(file_url, adsk.fusion.MeshUnits.MillimeterMeshUnit) # design.designType = adsk.fusion.DesignTypes.DirectDesignType # Create FormFeature root = design.rootComponent forms = root.features.formFeatures fFeat :adsk.fusion.FormFeature = forms.add() tBodies :adsk.fusion.TSplineBodies = fFeat.tSplineBodies # FormFeature start edit fFeat.startEdit() #Change Names of Meshes and Create T-Spline from them meshBodies = design.rootComponent.meshBodies for mBody in meshBodies: mBody.name = ' '.join([str(elem) for elem in mBody.name.split(' ')[4:]]) ui.activeSelections.clear() ui.activeSelections.add(mBody) #Create T-Spline for each model app.executeTextCommand("Commands.Start TSpline2BRepCommand") app.executeTextCommand("NuCommands.CommitCmd") # rename TSplineBody tBody :adsk.fusion.TSplineBody = tBodies[-1] tBody.name = mBody.name # FormFeature finish edit fFeat.finishEdit() except: if ui: ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))
