Visualization and transformation problems

Enrique
This post has NOT been accepted by the mailing list yet.
Dear All,
I am writing to ask for some help.
I used to work with ILWIS 5 years ago, but since I have not use it anymore I forgot quite a lot of things.
My problem is that I have two polygon maps, but I cannot visualize them together, the first one I open is shown totally, but as I add the second one it only shows a small part of it. Any advice/trick?

The main problem I am asking help for is:

I need unique ASC map from these two polygons.
My idea is to convert each polygon to a Raster, then glue the two maps together and then export the final map as ASC. I do not know if this approach is correct.
When I convert the polygon to raster, the result Raster is all white. If not the error 1002 is always appearing.
So if you could help me I will be really thankful!
Greetings and thank you in advance,
Enrique Sulbaran

Hi Enrique,

First check the coordinate system of the two polygons. You also have an option to glue them as a vector. Try to use the option "Union"  available in the version 3.8.3.
