Scale Up and Scale Down in part environment for Casting

Hi, 

 

I have question here, is there any way to scale up and scale down at the same time for part?

 

Basically i want to create an offset for a single part which means i need the outer faces to scale up 3% and for the internal hole or any other internal feature to be scale down with 3%.

 

I attach some picture for the reference:

Hi,

look for "Part Copy" command. It has option to scale 3D geometry.

You must instert your part using this command to new part. It can not be done on the same file.

 

Edit: sorry, it will not work for inner faces, only for outer.

Hi @ota_poul2

 

Thanks for the reply.

 

I know that part copy you can put the value to scale up or scale down, but it only can either scale up the whole part or scale down the whole things.

 

My objective is to get the outer faces to be scale up and inside features/faces to be scale down.

Current process I do is by using offset each surface and a lot more process until i stitch everything into a solid.

Is there any fast method to complete this?

You are welcome but I did not help you at all :-)

Unfortunatelly I do not know the fast and easy way how to scale a part as you desire.

 

Edit:

Actually there is a way how to achive this. You can use "Offset" command located on Surface tab. You can select all faces (Body) and then define offset value. Works for ordered and sync environment.

See attached video.

Hi @Arisy

 

 

I think You have to build Your model with multiple bodies, and here even with multiple parts.

An inner part and an outer part.

Both as full body (so inner part will not be with holes but with extrusions.

Then You can merge those 2 parts into a single new one, using different scale parameters for each of them.

 

Finally a Boolean Substract will bring the right holes into the righ outer part.

 

But BTW, I thon that a scaling is not the right "Offset" as mentioned.

Depending how far away the scale center is for every area of the model the absolut distance is quite different.

So if You want an offset then You night use an offset function.

Although not likely to help with your specific workflow, and more as an FYI for everyone, there should be a new "Scale Body" command in ST10.

 

Features of Model Scaling

  • Uniform Scaling
  • Non-uniform scaling
  • Change scale point
  • Dynamic preview
  • Sync features converted to facesets
  • Both Ordered and Sync modes

Applications

  • Scaled Prototypes
  • 3D printing
  • Shrinkage in mold design
  • Stretch Geometry

Hi uk dave ..

When can I download the ST10?
Is this week or next week? ...

Hi @ota_poul2

Thanks for the video. I appreciate that.

But how if I want to scale it using percentage just like part copy function instead of putting mm value?
Is there any way?

Hi Arisy,
if you use "Offset" command, there is only "distance" value. Perhaps some math calculation between distance and percentage should help.
