VituixCAD

Correction: most keyboard shortcuts seem to be working. It’s just the Optimize on/off/toggle from the context menu that don’t. Bug?

Again, I understand if that’s a low or no priority issue, as it’s not officially “supported” hardware.

Thanks for the amazing software!
 
But can you help with my first question?
I trusted you can see the difference. It's the same connection, but with different user parameter: C or R.

VCL lib is not done by me so there may be some others with close the same functions.

That works too via context menu and Ctrl+W. At least here with real W11 Pro. Components to be toggled should be selected (in blue).
Shortcuts with Ctrl-key don't always work because (mouse) focus is lost to somewhere else than panel containing schematic picture box. I have not tried to force focus back to the schematic.

sorry if already been asked.
Vituixcad doesn't start (or takes too much time, not sure how much) if the last project or any recent files were stored on a network share (e.g. samba share on a NAS) that is not accessible anymore/offline when launching the application.
This on windows 11 (regularly updated). Not sure if there's a windows timeout or if it's in the application.

Yes, I saw that it's just a different set of values, therefore I was confused by the name. The VCL ones said "unity gain", so I thought that the non-VCL one would not be unity-gain. But when I changed the Q or frequency, I did not see any change of gain, therefore I got confused.

My limited reading of active filters is that there is Sallen-Key topology and unity-gain, and while Sallen-Key is more flexible in the range of values one can use, it's not unity gain. That's where my questions and doubts came when I saw this other library labelled "unity gain".
 
Hello Kimmosto,

may I suggest a feature that I'm missing in your great software?

Would you be able to include a voltage curve in the power window of the enclosure tool? Maybe as a switch between current and voltage. when I'm trying to match a driver and enclosure to a given amp I often apply peaking, LT, HP and LP filters and I end up having to calculate the resulting voltage that my amp would need to supply by multiplying the input voltage with the filter gain. A voltage curve in the power window would speed this process up a lot.

Here's a simple example:
Let's say my amp is capable to deliver 40 V above 4 Ω.

Woofer in sealed box, input Voltage: 30V, no filters
30V w.o. Filter.png


same box, but with a 6dB peaking Filter at 135 Hz
30V w Filter.png

now the resulting voltage is 60V at 135 Hz, which my amp can't handle. Unfortunately I can't easily see that, unless i divide power by current or multiply input Voltage with the filter gain.

A Curve like this would help a lot
30V w Filter + V.png


I'd be really happy, if you could add that feature. Thanks a lot for your effort and your dedication to this great software.
