Re: VIIC 1:45 modell

The great blue one fresh from the body shop. Matt clear coat tomorrow. Some dents remain and only very few runners.
I declare this the new 2m class i.e. to be viewed from 2m distance.
Rudder sections finished and shaped. Made from Finnboard layers.

Re: Macro to compute center of mass

thanks for all the work in it. Some observations with my kubuntu/FC combo: 1) Icon/Box Layout still fixed and collapses to not beeing visible. As far as i can see you did introduce some global vars to set the icon and box sizes but you still use fixed numbers at the actual code lines. 2) When checki...

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...
