Free STEP viewer?
« on: October 19, 2016, 04:27:10 pm »
Hi guys,

Does anyone know a good, free, offline STEP viewer?

I tried STP Viewer (http://stpviewer.com/) but it does not seem to support colors in the STEP files.

Also, FreeCAD seems very slow....

I use STPViewer to double check my CAD exports before sending off to the machine shop. I didn't know you could even store color information in STP files.  What are you trying to view?

I am using the e-drawings feature of Solidworks.
There is a free version available but that one may not open STP files, I am not sure.

There is also 3D-Viewers, but I am not sure what the free version is limited to.

Yes you can, I want to use it to check my 3D output version of the PCB form Altium Designer

Autodesk 123D can import step I think.

You can try CAD Assistant - free for OS X, Windows, Android and iOS.
Supports viewing and converting plenty of formats including STEP with colors:

The current eDrawings reads STEP files and is simple! I have a STEP file for an embedded product (10 top-level product, 60 parts each in a 5-deep hierarchy with re-use of major electronics sub-assemblies). I'm reviewing the design and stepping through the hierarchy. How best to select and hide, or hide others, took some getting used to (and I still don't seem to understand correctly). You can also apparently markup a drawing (possibly to send back to the designer for another iteration) but I haven't tried.

Welcome to the forum.

Yes, the eDrawings indeed opens STEP files perfectly.

I just got a huge 165 MB STEP file from a customer, the largest file I got so far.
It opens in eDrawings right away within seconds.
But in Solidworks it needs about 5 min, to analyze all details, before it opens up.

I use FreeCAD as well.
Note of caution: it doesn't have the most intuitive workflow. You have been warned. ::)

On Wikifactory, you can view STEP files and a whole range of CAD formats without needing plugins or installs: https://wikifactory.com/

Take a look at this VR headset to see how it is viewable even on Mobile: https://wikifactory.com/+wikifactory/north-star-build/file/Assembly/LMC.step

We breakdown the feature here: https://wikifactory.com/+wikifactory/stories/introducing-our-brand-new-file-visualisation-system

You can use F3D to quickly view step files !

Here you can find various ways of opening a PCB file using offline software like Eagle, Altium etc.: https://www.raypcb.com/open-pcb-files/

Looks interesting.. just a question: can it also export step files? What I'm looking for is a tool which can compress / optimise STEP files. The PCB package I'm using produces massive STEP files which IMHO can be significantly optimised.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Pains me to say it but I think Fusion360 will import .stp (in fact, I know it will) and re-save as optimised. But the person to ask, to be sure, is beanflying who often regales us with his enjoyment of it and its capabilities.

Fusion360 absolutely imports STP -- I use that feature all the time, as PCB layout programs export in STP.

Once the model is in F360 I don't particularly care what the program does with it.

If anyone stubble on this thread I just found Mayo as a great stp viewer because of the following:

- Color support
- Dimensional measurement
- offline, no subscription
- fast and light
