If you want to create your own dot patterns have a look at these Apps.. they are free and do not rely on scripting , meaning they run independently / stand alone and the patterns can be copied to both the community and pro versions of Qcads hatch pattern folders..
Points can easily be created in seconds and BPM offers an easy way to create them BHT can create offset and also shifting points..
Here are some screenshots plus forum links too..always happy to help..
They are both extremely easy to install and use and if you have any questions regarding these apps please feel free to PM myself or forum user PeteVick..
