    Thank you for the update! I was wondering if there any way to change the size of the Summed freq response on the screen? It is cool to have all plots on the left, but sometime you want to have bigger one for the summer response.

      Do you mean graph of Calculator tool or Merger tool, or main program (having graphs on the right)?

        Main program, sorry for that. That one.

            Thank you so much! The more I play with your software the more I find it to be so good!




            One more question, more for measurements.




            Do you have in mind measuring drivers on its axis for each drivers? If so you will have “reconstructed/simulated” responses on listening axis for drivers which are it on the axis.

            As another way, is it possible to measure on a listening axis (let’s say tweeter) and then not moving the mic measure all other drivers and use those responses? In this case how are we going to use those off-axis measurements to model all off axis responses with the software? Do I make any sense?

              Maybe I've already linked this pdf here: Preparation of response measurements for crossover simulation with VituixCAD
              That system is a bit complex but quite professional and valid for any construction no matter driver types (cone/done/planar/horn), how many drivers/ways you have, where they are located and how aimed. So, you should not try to avoid mic moving or speaker lifting to measure different drivers because individual origin for each driver allows (quasi) 3D simulation producing power and DI responses and off-axis responses in both planes. However, if speaker is small 2-way or 3-way with circular radiators, you can keep mic at the same elevation (between the drivers) while measuring tweeter and mid-woofer in horizontal plane.
              Recommended tools and method may look too complex in the beginning but also beginners have succeeded to design full size WWMTMWW ready at once - without need of crossover tuning by listening or room response measurements.

                Thank you! I think those capabilities of the VituixCAD are just amazing. No those measurements do not look complicated at all pretty much what you should do if you want to get as much of your mic as possible. Contrarily, I think those are really good instructions for a beginner, for someone experienced you know what exact measurements you need, what to expect from a certain XO topology and driver arrangements, so not always necessary to sim everything. Just double check it with real measurements in the end :-). However, if you are up to something crazy, that where were your software is the top!
                Oh i dont know if it was discussed, in the optimizer is it possible to make the range for optimization somehow graphical? Lines like in LspCad maybe? (I am using v1, maybe it is already implemented in v2

                  Version 2.0:
                  Ends of target lines indicate optimized frequency range with all selections.

                  Version 1.1:
                  Ends of Axial response and Power response target lines indicate optimized frequency range.
                  Optimized range of Axial response of Way and Filter gain of Driver are not graphically visualized. User should look values in the text boxes.

                    Rev. 2.0.3.11 (2018-07-15)
                    Selected component can be replaced by pressing Ctrl key while clicking menu button. Active block can be replaced with another active, and passive component (LCR) with another passive. Values of parameters with the same name and unit are copied to replacement component. Driver, ground, library block and wire cannot be replaced directly without delete->add.

                      Rev 2.0.3.12 (2018-07-21)

                      * Automatic part numbering added for passive (LCR) and active (U) components. Part number is shown in crossover schematic by checking View->Part #.
                      * Part # added to curve tooltips of resistors and inductors in Power dissipation window.
                      * Pmax added to curve tooltip of resistors in Power dissipation window.
                      * Part # of passive and active components saved to project file (.vxp) and library blocks (.vxl).
                      * Type and Nbr columns replaced with Part # column in Library block parameter window. Part # created if not found in existing/old library block file. Part # forced to show in schematic while creating new library block.
                      * OP amps. added to Parts list.

                      Active buffers will be associated with power amps later to restore impedance and output power responses for each "way" as they are in version 1.1.

                        Rev 2.0.4.0 (2018-07-26)

                        Main program:
                        * Maximum power (Pow parameter) of resistors shown in crossover schematic if View->Power is checked.
                        * Part numbering of active buffers changed from U8,U9,... to A1,A2,... to help association with power amplifiers in active multi-way.
                        * Load impedance (magnitude) of active buffers shown in Impedance chart.
                        * Added 'Load impedance of Buffer' export.
                        * 'Total impedance' renamed to 'Load impedance of Generator' in Impedance chart and Export.

                        Power dissipation window:
                        * 'Output volt-ampere/real power' curves renamed to 'Generator volt-ampere/real power'.
                        * Output volt-ampere of active buffers shown in chart.

                        Enclosure tool:
                        * 'Crossover of current driver' checkbox renamed to 'Crossover of driver'.
                        * Driver dropdown list added below 'Crossover of driver' checkbox. No need to select driver from schematic in the main program to apply filter transfer function for enclosure calculation.

                        SPL Trace:
                        * Added warning 'Low impedance must be >0 with logarithmic scale'.

                          kimmosto This is an incredible resource, thank you very much for spending such extreme effort on this thing for the community!

                          Also a note - if you ever do decide to change layout / placement behaviors for components, don't remove drag and drop. Simply add whatever the new technique may be as an alternate option from configuration. That'll ensure a broader audience while satisfying some particular "approach" some people like (relative to other software) compared to this. I refer to a previous post that mentioned this.

                          Thanks again, very nicely done!
                          Feel free to rip my assumptions apart when wrong, or fix if close.

                          Passive Radiators:
                          All PR(s) Vd must at-least double all woofer(s) Vd. Calc = Sd x Xmax to get Vd for all PR(s) and all woofer(s). If all PR(s) Vd at-least double all woofer(s) Vd they'll work.
                          For woofer(s) with large Xmax vs Sd, all PR(s) with Xmax at-least double all woofer(s) Xmax will work.
                          A PR max weight is said to be its Mms x3

                            Thanks!
                            Just a quick comment about drag&drop. Standard drag&drop in Windows is not commonly used in circuit editors because visualization works with size limited bitmaps which is not able to show bigger blocks or groups. I tested this in the beginning with version 2 and decided to implement move command by redrawing whole network when user moves mouse cursor more than half snap grid or presses arrow keys. Due to restrictions component adding is done without standard drag&drop and dropping of library block from file system shows only [+] image in the center point of block to be dropped.
                            Duplicating (dragging with Ctrl key pressed) is possible implement just like drag&drop, but so far user should use copy+paste either via context menu or Ctrl+C,Ctrl+V.

                              ^ good point. That's forever been a key drawback of legacy winforms on the platform. It's one of the reasons (as an engineer who highly prefers C#, a lot) I was so happy to see WPF+XAML with vector-based elements finally show up to replace it after decades of old methods.

                              Scaling is simply trivial with little to no loss in granularity or quality (within reason and type of visual). The core representation of an image still has to be created though.

                              There's probably code to parse icons into vector (of varying success) but I haven't needed to look, and now I'm going way OT.
