Is it possible that cplane is turned on after opening software or software starts always fron World->Top ? I have named cplane which is very close to original origin and I wonder if its possible that I had cplane turned on after opening software and I haven`t noticed that.

Custom CPlanes are document properties stored in the file/template - they are not global options. If your template or file had a non-standard CPlane active when you last saved/closed it, it will (in principle) open with it still active. On the other hand, if you have not messed with your default t…

[image] Marcin: What commands handle the Cplane center, axis? I think that not only mirror. Mirror doesn’t care about the CPlane origin (what you are calling centre) - it only cares about the active CPlane Z axis direction to create the mirror plane from a line (two points). That is the cas…

Hehe. Please do not say that I should always hit 4views twice when I leave the software after 10 hrs of modeling at 1 am :slight_smile: I only kindly ask to allow the user see if the Cplane is changed or not especially when the scene is opened. I model alone not in team but I don’t remember what I s…

Hi Marcin - [image] Marcin: I think vieports should have for example small 1px frame if cplane is turned on. [image] Marcin: I set up a temporary centre for the front of the car and the rear of the car (for modeling purposes). From the description in this thread, it sounds like you do…

The difference between the default cplane and the changed one is very small: about 1 degree and 2mm but it’s crucial to fit the final parts to the car after production. How could I notice that on the viewport? Or maybe I am missing some indication there. If it’s bad then I will trim my bumper badly …

Hi Marcin - [image] Marcin: […] but I check this all the time like a crazy person and I feel that is additional stress which could be taken off with some indication. Perhaps you could use named views? Those save the active CPlane at the time of saving and you see from the viewport title whic…

I use NamedCPlane command. Could you show me where is shown which is active? [image] you see from the viewport title which one is supposed to be “active” Could you show me that viewport title?

[image] Wim Dekeyser: Perhaps you could use named views? Those save the active CPlane at the time of saving and you see from the viewport title which one is supposed to be “active”. @wim The viewport title shows the name of the view, not the name of the Cplane. If the Cplane is changed the n…

Maybe it’s a good idea to follow the name of the viewport with the name of Cplane which is active in that viewport. If cplane is not default but it is not named it could be named as -''not default". For example: Perspective - NameOfNamedCplane Cplane Top View - not default Cplane Bottom View An …

[image] Marcin: I use NamedCPlane command. [image] Wim Dekeyser: Perhaps you could use named views? Named views, not named CPlanes. [image] David Cockey: The viewport title shows the name of the view, Yes, and a named view saves the active CPlane. I’m not saying that named vie…

[image] Wim Dekeyser: named view saves the active CPlane. Could you show me where it’s shown because I don’t see that at all?
