scaling/resizing question

[peolini]

Hello All,


I'm very new to this forum.


I have been searching for a while but can't seem to find the answer to a question I have for some time.


I know the "scale" option in SW, but that only gives me a the possibility to scale parts in percentages of the original.


But, is there a way to resize parts just by typing in a new size/dimension?


Hoping on some positive feedback and thank you in advance,


Dennis

Is not clear for me what you wish to achieve.

If you wish to scale you say that you know how to.

If you wish to resize you can edit the sketch and replace old values for dimensions with new values.
Or:
- double click the part - this will show all dimensions;
- double click a dimension and input the new value;
- click REBUILD button.

Hello Mihail,


Thanks for replying.


I am trying to resize a complete part like this:
http://i265.photobucket.com/albums/ii229/peolini/cylhead.jpg


Themain bodyis now drawn about47 x 28 x 15,5 mm (lxbxh)
and I would like to reducethe entire partin size to about 5 x 3 x 2 mm just by punching in 5 for x, 3 for y and/or 2 for z without having to work out the exact percentages first.


I hope this makes sense,


Dennis

Unfortunately steel that have no sense.



I compute your dimensions this way:

Old_x = 47 New_x = 5 => New/Old = 0.106

Old_y = 28 New_y = 3 => New/Old = 0.107

Old_z = 15.5 New_z = 2 => New/Old = 0.129



So you have different scale in each direction.



Say that, for linear dimensions, can be done (mathematical).

But how to use different factor of scale for the circles (cylinders) ?

Will become ellipses, isn't it ?



Note that SW is not as intelligent as a human.

So, even if you have only linear dimensions, SW will refuse to do the
job because it "know" that it is not a general method to do that.

>True, but my method would be like I am doing a 3D sketch of the part that looks good and after that I want to givethe partthe right dimensions.
At least that is the idea.

> yes it will become an ellips, I know that. which would be no problem to me.

OK so I know I will not have to search any further for a solution.
I will just do it the "hard" way and scale parts proportionally.


Thank you for your explanations.
