Absolute:Local question

ajjjjjjjjjjjjjjjjjj — Tue, 31 Oct 2017 20:45:03 GMT

Hello forums!

I have a very quick yes or no question i was wondering if you could answer,

I have 2 exactly the same meshes in a scene, one i scaled by using the gizmo but i dont remember how much. I have the exact numbers in Absolute:Local.

The numbers are the same since i scaled uniformely i think. Im just wondering, can i copy and paste the numbers from the Absolute:Local to the x,y,z Absolute:Local?, since its the same number will it count as scaling uniformely right?

Also how exact can 3ds max scale?, how many digits can you scale to?, is it only hundreths (.00x) or possible to scale even more manually?

Thank you and if i explained poorly dont hesitate to ask!

Thanks!

If the x, y, and z values shown in the ScaleTransform Type-In box are the same then the scaling is uniform.

Also how exact can 3ds max scale?, how many digits can you scale to?, is it only hundreths (.00x) or possible to scale even more manually?

This is a more difficult question to answer. 3ds Max has a double precision data base. This means that the precision of coordinates is limited to 1 part in 16,777,216 (2^24) or about 7 significant figures (which is not the same as 7 decimal places). As an object moves further away from 0,0,0 the absolute precision stays the same but the number of decimal places decreases. YOu can examine this effect by going to Customize, Units Setup..., and then System Unit Setup. There you will see if you are 1 unit from the origin the precision is 0.0000001192

However, if you move 100,000 units the decimal precision is reduced to 0.0078125.

The absolute scaling of an object is not limited to hundredths (which is 0.0x) or thousandths (0.00x). Note that the scale command uses 100 for full size not 1. So 1 represents a scale of 0.01 or one-one hundredth. You can see more decimal places in the scale command if you first (before scaling) increase the Spinners Precision at Customize, Preferences, General.

Thank you for the reaponse!,

is ther anyway to check the exact scale/size of an object?

If you are asking how much an object has been scaled using the Max scale feature then just select the object and look at the values at the bottom of the screen or open the Transform Type-In and note the value.

If you want to know the size of the object compared to a real world scale then I would set object snap to vertex and then use Tools, Measure distance and find the distance between two points and compare the Max value to what it should be. You should of course make sure your active units are appropriate both in Units Setup and and its System Unit Setup option.

Thank you for the quick response!,

how would i see the thousandths and the decimals after that?, or is it not possible to scale so small with manual scale?

After setting the spinner preference to 7 decimal places (as noted in an earlier post) here's what you would see if you scaled a teapot by 0.1234567 (% implied. This is a ratio of 1 : 0.001234567 or about one-thousandths as big.

Thank you again!,

One last question, what is the max amount of decimals you can set it to?

Go to preferences and see what it will accept.

Hi friend

Here is another option you can try.

Select the other model and "Alt+A" align tool and select match scale x,y,z. This will scale it up or down exact the first model.
