I quess: Your "topography.tab" is a vector contour of heights (polylines), and "spotheight point" is a point table with heights.
Do you want to add the two vector height tables to one and make a grid of it ? If so you can convert the polyline (contours) to point in VM > Create Grid > Poly to Point menu. Then add the point to your original point height vector and grid it to raster in VM. VM can not use breaklines in interpolation. It has to be points.

Now I am trying to convert the map into grid. After creating the grid, I realized that only points data of tab file were used, while there are a lot of counters elevation data unused. Now how can I convert these line data into spotheight point in the tab file? If I convert these line data into spotheight point (point data), I will be able to create a grid file with a good resolution.
