The problems are:-1) How can I draw or plot in QGIS?2) How to load CAD Tools plugin into QGIS?3) The QGIS version 1.7.4 have nice feature, but i can't load the google maps as base map. Everytime I click, the QGIS will automatic close. This happen for me when using QGIS version 1.7.4. Please help. Can you pass to someone which can help me?
