Hai,
happy new year to all,i want to use stitched via’s in my design for some signal.in kicad 7.0.8 what is the options.
First, update your post. KiCad version numbers have three numbers and two dots. (It’s quite amazing how many people get this wrong).
Second, Update KiCad. Currently it’s V7.0.10 and there have been quite a lot of bug fixes. A bug fix release (increment in third number) is released approximately once a month.
Third, your actual topic. KiCad has two ways of placing via’s. One is during routing of a track. Draw some track segments, press V to place a via and continue drawing a track. These are “automatic” via’s, and their net name gets updated automatically if they become part of another net somehow. The other way are hand placed via’s and these are placed with: PCB Editor / Place / Via [Shift + Ctrl +V] (or with the via button in the toolbar on the right side next to the appearance manager). Via’s placed this way have the checkbox [ ] Automatically update via nets turned off. The net name is determined only once during placement (but this can be changed in the via properties.)
DRC generates warnings for: Warning: Via is not connected or connected on only one layer.
PCB Editor / Tools / Cleanup Tracks & Via’s has a few options for deleting unused via’s. But it does not delete a via when it is locked. Experiment a bit with these settings and how they work (in a copy of your project, or make a backup first).
Once a via is placed, you can make an array of them. An easy variant is to create a single dimensional array outside the board area (with a certain pitch) and then use copy & paste (and rotate before final placement) to put the via’s on the PCB.
For completeness: You can also use a THT pad as a via. THT pads have more properties, you can for example use the solder mask layer to expose the via / pad. It may be convenient to make a custom footprint with an array of via’s. For example for high current connections between layers. This technique is also used extensively in KiCad’s own libraries for thermal via’s.

hai ,
Thanks for update version. I got i idea about normal vias .but i need to implement stitched vias for cooling process .in polygon i need to fill with copper pouring with via.And one more think how to give the cooling pad for component .
What does this mean:
Maybe have a look at any footprint in KiCad’s default library with the keyword “thermal” in it. Those footprints use THT pads for thermal via’s. (Edit: Oops, I already mentioned that 
)
I see you still have not updated the version number in your original post…
