Full Version: Is there a way to zoom on screen to actual size?

Good day.
This might a weird one...but is there a way to zoom to actual size?
so let say a circle is 50mm and on screen it is actually 50mm?

I am making a metal flange and I just want to put the gasket on the screen to see how close I am.

Tnx!

Sorry no there isn't anything set up for that.

There is not any way for a program to automatically know how the physical dimensions of the current display. It can find out the resolution of how many pixels it has but not the actual physical size of them.

Now if I have a known object and match it to the screen is there a way to lock the zoom to a known number so If I come back another day to be where i was?

Yes, it is possible to save and then restore the current zoom level later on.

When you want to save it, use File > "Save As" and save to a .3dm file. Maybe name it something like "my project_saved view1.3dm".

Open the .3dm file you just made and delete all the objects in it and resave it.

Later on if you want to return to this view and zoom level, use File > Open to open your saved view .3dm file.

Then use either File > Import or copy/paste to bring in your objects. When you use "Import" that will bring in the objects without changing the current views unlike "Open".

There is also a "View Manager" plugin you can set up to save/restore views:

Scan your gasket. Then you can bring the image into MoI and have a good ref for 50mm….

I also have these. They measure pixels, but you can measure known values then translate the values to calibrate your current display zoom…

I found Its kinof an odd attempt though. I think accepting that your screen is a digital representation and you can just trust MoI to give you accurate output is best

I ended up getting a Mitutoyo and other methods for real world measurements and just entering values. I was overthinking it….

I know it is odd.
but my scanner is far away from my cnc computer.
So I just put the gasket on the screen for some odd shapes and get it done.

But I do have multiple ways of doing things....I do have a cnc probe..but sometimes it just takes too long..
I will be getting an old scanner in shop for these things,

Also installing a camera above my machines so it can auto trace with close enough measurements.

Ill just use what is faster.

tnx.
