Can´t scale down and correct thickness

[swerecon]

Hi,

Iám into some hobbyprojects and been sent some files from a company. I got the whole model more or less but i have problems solving two issues with only two files.

First problem is the hood. I cant change the thickness of construction parts. Problem need to be solved becouse i would be 3D printed and as for now it will only be 0,3mm thick. 

2nd problem is interior. When i scale it down, a lot of parts are spread out wide and some parts just scale down.Probably they dont have the same origo, how to fix that?

Both files attached as RAR compressed STEP-files, hope someone can help me.

Can you Attach *.zip rather than *.rar? I don’t own a license to a rar extractor, but I do own a license to Windows OS which can extract *.zip files.

These parts are too complex in geometry to just be changed to a different thickness.

My guess is that you don't have enough experience with CAD software and 3D Modeling and my suggestion would be to start with a simpler project.

The Win-RAR program is free to use

Hi and thanks for replay. Thats true iam not an expert, but the rest of the files works great and i have remodelled most of it from scale 1:1 to scale 1:14. Created the camfiles for my CNC and also 3D printed some parts. BUT, i have problem with only these two things, thats why i ask for help. If you cant help or interested to help me, dont replay.

Can you share what you have done so far, so we can assess what level of detail you want to retain ?
