Sketchup and Miniature Modelling STLs

[Grizzly256]

Hi All

New here, but long time sketchup user.
Using Sketchup 2017 because its free.

I am hoping ya'll can help me, I am using sketchup to edit some STLs files for 3D printable miniatures (WH40K to be specific). Now i know sketchup probably isnt the best software for this and that it inherently can handle very small geometry, but i am wondering if you may be able to suggest some workarounds for my specific issue.

When i import STLs into sketchup, it takes a very long time to process as it is drawing all the polygon lines onto the model. It also struggles to fill in curved areas some as corners, domed rivets and other curved edges. I have tried the daves method of upscaling the model, but this seems to have little effect.

Is there some plugins or other tricks you can reccomend to help a brother out.

Did you try using Skimp?

@Rich-O-Brien No, I am not familiar with that.

If you set the import units to meters the model will import as if millimeters are meters. and you'll be less likely to have issues with holes in surfaces. Rich's suggestion to use Skimp is a good one for simplifying the geometry after you have the .stl imported.

Set model units to meters and leave the model at the larger size. When you export the .stl again it should be in meters but will open in the slicer in millimeters. Look at existing threads in this category to see some other examples I've shown.

Ok, so i have got the 5 day trial version of Skimp, much faster importing STLs and no geomertry issues, just the 5 day limit is annoying.
For some reason, when importing the STL via SKIMP, it comes out like this (see image). I cant figure why i cant find which settings to turn of to bring it back to normal.

Tried the "set the import units to meters the model will import as if millimeters are meters.". Problem is, it doesnt give me an option to set the import unit when doing so. I just click File-Import-Select File-Import. I never get the option to set import units. Is this a limit of Sketchup 2017?

It's not a free extension. If you need it and it saves you time, it's worth paying for. The alternative is to do what it does manually.

You can get the option to set the import units. After selecting the .stl and before clicking Import, click on the Options button.

What's normal? Looks like you just need to adjust edge softening. Share the .skp file so we can see exactly what you are working with.
