Re: VIIC 1:45 modell

@shupin since the FC "Material" probably takes a while to accomplish, could we get a "set default density" button and input field for the time beeing ? Now i do change the macro for every "main" material in the selection so i do only have to set a few remaining bodies. BTW very nice job, your macro ...

Re: VIIC 1:45 modell

Center of masses with a lightly patched macro of shupins main work. The purple sphere indicates the "wanted" COM and the red one the actual COM with motors, batteries etc installed. The distance is approx 65mm aft. The overall weight should be around 3kg (theoretically). According to FreeCAD and the...

Re: Macro to compute center of mass

just found that for multiple arrays or clones thereof there needs to be an additional patch around line 276: # Find the center of mass depending of the type of object. if hasattr(objs[sol], "CenterOfMass"): self.centerofmasses[sol] = objs[sol].CenterOfMass elif hasattr(objs[sol], "Solids"): # self.c...

Re: Macro to compute center of mass

Around line 300 this patch seems to work. But i'am not 100% certain. May be a professional could have a closer look at it. #2: an array is selected if hasattr(sel[sol], 'ArrayType'): if sel[sol].ArrayType == 'polar' and sel[sol].NumberPolar > 0: # self.centerofmasses[sol] = sel[sol].Center self.cent...

Re: Macro to compute center of mass

Thanks for this macro and i'am using it currently to get the COM of my VIIC. Two issues i did find though but maybe it is just me beeing to much oldschool and not OO compatible ... 1) There might be a bug within the polar array calculation. The macro does not step through the solids in the array but...

Re: VIIC 1:45 modell

Deck cutting took about 4.5hours overall for 1mm finnboard. You might want to add max 10% spirit (ethyl alcohol; "Spiritus") to your resin. This ensures that the resin will not harden rock solid. The deck will be held in place by neodyn magnets. 15W Laser: Speed 500mm/min , 2 passes, Light intensity...

Re: VIIC 1:45 modell

Deck Layout (Directors Cut). First test sheets, on the right, resined and ok. Material will be 1mm Finnboard. But i do have to re-tyre my laser cutter. We do have a disagreement about "linear" or "straight". If that won't help i need to design me own one with linear bearings and stuff (but boy am i ...
