★How to correct lines in ZWCAD raster image vectorization

Issue: 

Due to the nature of raster image vectorization, orthogonal lines often exhibit deviations after conversion, resulting in lines that are not perfectly vertical or horizontal.
How to avoid this?

Solution:

1. Go to the Ribbon Smart tab and click Vectorization Configure (or execute the VECTORIZATIONOPTIONS command) to enter the configuration interface.
   
2. Click Edit, navigate to the Fit tab, enable Support Ortho Adjustment, and set an appropriate adjustment angle based on the specific drawing conditions.
   Click OK and then proceed with the raster image vectorization.
