HyDraw CAD from VEST,inc is powered by Autocad OEM engine, with standard 2D Autocad® commands.

Here are some useful options to customize your HyDraw:

diby typing PICKADD, standard value is 2. Pickadd accepts 0,1 and 2 values
0 : each new selection removes previous selections. To select more objects you need to press SHIFT.
I find this setting useful when I need to check model properties because I don’t need to press ESC everytime I need to unselect a symbol

1: each new selections is added to previous selections. To delete an object from selection: press SHIFT

2: like option 1, but if you use SELECT command, selected object will remain “selected” when you exit the command.

It is possible to create keyboard shortcuts for those commands you are using more frequently. You need to edit file hydraw.pgp inside directory C:Program FilesVESTHyDraw CAD600Support
Inside that file you can find all standard shortcuts for Autocad commands (M for MOVE, CP for COPY, …)

by typing RESETCON, each connection line you select gets corrected.

to regenerate connections, useful if you replace a symbol without drawing new connection lines

with LTS you can change global line scale for your drawing
