STEP- and Gerber- File viewers ?

(1/5) > >>

Uky:

Q1
==
I have been trying to find a small free-of-charge STEP-file viewer that does NOT require creating an account for downloading.
NIST viewer works but it wants to mess with my protected folders and has a user inteface that is "a bit cumbersome". It
also opens a browser to some NIST resouce page. I searched and found several but either they have become payed versions
OR they require creating an account OR they are simply defunct.

Q2
==
I have for a long time used the Pentalogix "ViewMate" free gerber viewer. It does the job OK and it can interpret Gerber files with
various settings for precision and standard (Metric/Inch/Mill). But it cannot "decode" drill files - even though they are created using the same
standard, like eg. Metric 4.3. Omitting/Including leading or trailing zeroes does not make any difference. A displayed file ends up with totally
wrong scaling.

There are "on-line" viewers out there but these are absolutely out of the question because of NDA's signed with my customers.

freecad and kicad can probably do it, but if your customers are big enough that they required signed NDAs why does it have to be free?

SiliconWizard:
FreeCAD works fine for viewing STEP files, although its UI is quite horrific. To each their own.
And yes, KiCad's Gerber viewer is ok too. You can use it standalone. There's also gerbv. You can also consider ZofzPCB, https://www.zofzpcb.com/ , which is quite good, but Windows-only for now, if that matters (and it doesn't run properly on Wine).

Smokey:
gerbv for gerbers.
