prevent user from rectangle selection

[essam-salah]

hi

im writing a c# plugins and prompt the user to select some polylines, the problem happens when the user select with rectangle selection (because it makes non ordered seclection), but selection one by one or using fence selection it keeps the selected objects ordered. 

the question is : i want to know if  there is way to prevent the user from making not ordered selection.

any help will be appreciated.

Have you tried to use GetEntity() in a loop.

Hi @kerry_w_brown ;

thanks for your respond, it seems good but i want to allow fence selection too. if there is a way to let the user use fence selection only it'll be great too.

The difficulty is that any box/fence selection just gives you a bucket full of objects stacked in an order that you have no control over.

But fence selection always gives me an ordered selection.

I found some time to play:

SSGetFilterByFence() ...

may help you.

There may be a way to be able to combine single selection and Fence selection ; using a keyword event trap to switch between modes. It would probably get a little messy handling the changes between modes because the selection set would need to be built then added to for single picks then etc, etc, but I think it would work.
