How to scale an assembly in one direction? I have modelled a stand and now the height needs to change from 900mm down to 750mm without affecting the other dimensions.
There are a number of parts in the assembly and I don't want to start over
Your zip file doesn't contain any parts, just the assembly file. Use Pack & Go to include all parts & toolbox items.
This would depend on how you've created the model and how the height dimension is effecting the other dimensions/design.
You may look into using scale feature and do the scale in one direction only.
You can save assembly as Part file and then scale it in one direction.
File > Save as > Select file type as .sldprt (select Preserve ids option) > Save
