scaling and fixing of front-views #258

Closed plc-user closed 1 year ago

plc-user commented 1 year ago

I would like to continue scaling of those many elements in the sub-dirs of elements/10_electric/98_graphics/99_assembly_plan/01_thumbnails_mounting_plate/ which are not to scale. In this context I would then also remove the terminals from these elements ... may I?

Merged, thanks. Why not, but sometime is usefull to have terminal in these element... https://download.tuxfamily.org/qet/scorpio/2022-7-23_Vibrafloor.pdf#page=6 https://download.tuxfamily.org/qet/scorpio/2022-7-23_Vibrafloor.pdf#page=16 https://download.tuxfamily.org/qet/scorpio/2022-7-23_Vibrafloor.pdf#page=17

Salut Laurent! In my opinion, using front views for drawing connections is not very professional. The way I learned electrical engineering (and think it makes sense) is to keep a clean separation of block diagram, schematic and layout drawing. This is one thing that many amateurs do not want to admit: A schematic has nothing to do with the real assembly except the function. For a layman it is of course easier to see where which wire has to be connected if the plan shows the front of the device (compare breadboard view of the "Fritzing project"). If we find it necessary to use front views for wiring diagrams, I think the reason is the lack of schematic symbols for that device. That's why I make it a point to include schematic symbols AND front views of the devices in the elements I contribute to the project. In the case of your plan on page 16, from my point of view, similar schematic symbols such as Wago 750-8215 or 750-1500 could also complement the portfolio of Schneider symbols. In this case, there is a combination of "all-pole" and "single-pole", which is otherwise not possible at this point (similar to your plan on page 21 for the ABE7-H16210/11 device). In case of a plan like your page 6 is in my opinion a classic example for "master-slave components": e.g. power supply and electrical signals in a master and the LAN or fieldbus cabling in slave modules. Otherwise there would also be several symbols in the BOM for one device. That is why I have formulated my proposal that front views shall not have any terminals: There is no need to have terminals on front-views if we have schematic symbols for every device.

Hallo PLC-user,

so ok
