When importing STL, want some indication of actual size

I’m a new CC user and the primary reason I bought CC is because it handles the reading of STL files, and subsequent toolpath generation, in a reasonably straightforward manner. However…

CC doesn’t provide any information about the actual or native X, Y and Z sizes found in the STL file. In my case, I’m importing an STL file for a mandolin top that I obtained from a vendor. Unfortunately, the vendor didn’t provide any specifications in a README file, etc, so I have to get the sizes by reading the STL file.

Since CC doesn’t provide any size info, I have to guess a size for the design, import the STL file and then provide scale factors of 1. If the size I guessed is too small, the design (mandolin top) is truncated on left/right and/or lower/upper. I have to increase thedesign size and try again.

It would be far easier if CC could read the STL file, report the sizes and then give me some way to set the size of the design appropriately… plus, maybe, some extra room around the perimeter to account for clamps, etc.

Or, maybe there’s a better way to tackle this problem? I did see some other topics that covered this issue and even had similar requests but these topics have been closed. I’d provide a link to the topics but I’m not sure how to do this with this forum software. (I’d be happy to get some schooling from expert users.)

To get a link from other topics, open the topic in question, scroll to the top if not already there, then at bottom of the the first post, look for the ‘link’ icon:

Hit that, then switch to the post you are creating, and hit ‘Paste’ to get the link into your post.

The forum software will automatically provide a preview of the link when you post your topic.

For example, here’s a link to this topic!

You can actually link to any post in a topic, each post has its own ‘Link’ icon.

Older versions did require that one manually specify the dimensions — that led to a lot of tech support questions about size.

Usually, when working w/ an STL, folks accept the size as specified in the file itself:

guitarbridge.stl (23.3 KB)

Opening that in a program which will open STLs we get:

If we then open up Carbide Create and make a rectangle of that size:

switch to the 3D modeling tab:

Import STL and select that file:

Adjust to the desired 3D Orientation:

we see that a Scale of 1.0 imports at the desired size (or pretty close):

If you have a file you are having trouble with, please let us know the specifics and we will do our best to look into this with you.

Thanks for clear instructions - very helpful.
