Thank you for reaching out and sorry to hear you are having trouble exporting asset in SVG format in XD. Would you mind checking this article: https://helpx.adobe.com/in/xd/kb/import-export-issues.html and see if you're exporting which is not supported?
We will try our best to help.
> When we export any asset in SVG format, it gets placed in a corner and we end up opening it in illustrator and again exporting it.
Illustrator generates SVG in a wrong way - because the file needs to be read back in Illustrator, I presume. What XD produces is the correct SVG.
