While in drawing mode I start a sketch in a view. I want to sketch in lines constrained to existing lines and arcs. I use the convert entity tool to convert a line, it highltes OK. When I try to draw a line from the highlited line, it will not snap to it nor can I constrain the endpoint of the new line to it. As soon as I start the line command, the highlited line becomes unhilighted. I used to do this successfully in the past but I cannot do it now. Was there an automatic update possibly performed in Windows XP that has effected this function as in an earlier problem with added dimension text not showing?
