Ok but that's what I proposed to you in my 1st answer.
"If you edit your cartridge; You select where you have designation and on the left see can link this function with designation3. Just look for it in the room settings."
Since you want to:
"Well , I would like the "designation3" property of a room to appear in the "Description" property of my plan."
Well, that's what I explained to you, you fill in this property in the room and to get it back in the drawing; you have to edit it and create a link with the part so that it appears in the drawing...
Well, well it's not moving forward. always the same answer, and I conclude that it is not possible to have a custom property of the plan that will look for a custom property of the room.
@ Sylk:
The custom property 'designation3' of my part appears in the title block of my drawing.
I think that yve is trying to copy the custom property of his part into a custom property of his plan, the ones that are in the "Summary information" dialog box and I don't think it's possible other than by macro, the equivalent of what Mycad tools surely do.
The advantage is that the "Description" property of a SW document can be displayed from Windows Explorer. And when you look for the plan of the engine mount or the washer among a list of documents named "plannumber.slddrw", you don't necessarily want to go digging through the nomenclature every time. For the parts that are named rondellebidule.sldprt, I chose to repeat the nomenclature marker in "Designation"
I have Mycad and I created this link function. Simply, I will generate my plans automatically with integration (just put 3 views on the right background and save in the right name), before sending them to subcontractors who will do the quotation. And these subcontractors don't necessarily have myCAD.
