Topo to Grid

I am working for an Civil Engineering consulting company.

We have a lot of Topo maps (autocad drawings with elevations).

I have no problem converting these cad to a line shapefiles with

Then I tried to convert these line shapefiles to grid with spatial

The probelm is that the density of the contours varies and I get a lot
of "black spot" (no value) in my grid.

I know using neighborhood stats can fix it somehow but i lost

Any better ways?

1. Float Grid/ Integer Grid in arc/info , arcview

In Arc/Info grid, float cell value could be added togather using DOCELL,
in Arcview, however,only integer grid has a VTab. So I do it by multiply
a constant then convert it to integer grid, dividing the sum by the
constant. The problem is I get a different results when using different
constant such 10,100,1000....   What is the right answer?
