How to keep the 3D object in the same measurement/dimensions from XVL Studio to Corel Draw?

I am very new to Corel Draw and have this basic query to clear. So, I have a bunch of OBJ files which can be opened in XVL Studio Corel Draw Edition. Now the OBJ files has 3D models that are already created to a certain measurement/dimension. Now when i send the OBJ file from XVL to Coreldraw, it opens in a different size. How do I keep the measurements exactly the same? How do i export or send the OBJ file from XVL Studio to Corel Draw and keep the measurements of the OBJ 3d model same inside of Corel Draw ? The 2D snapshot inside corel draw keeps changing.
