BlastCAD runs in the browser — most Ctrl+key combinations are reserved by the browser (Ctrl+N, Ctrl+O, Ctrl+S, Ctrl+A, etc.). Use the top bar buttons and ribbon for file operations. The shortcuts below are canvas-level keys that work when the 3D viewport has focus.

When a drawing tool is active, you can type coordinates directly into the Command Terminal:
Syntax
Meaning

Absolute: X=100, Y=50
@10,5
Relative: +10 X, +5 Y from last point
@10<45
Polar relative: 10 units at 45° from last point
10
Direct distance: 10 units in the current direction (with Ortho/Polar active)
Tips for Power Users
Repeat last action: Press Enter or Space with no active tool to repeat the previous command.
Multiple selection then operate: Select several holes or entities first, then invoke a command like Move or Delete to apply it to all at once.
Direct distance input: When Polar Tracking is active, move the cursor in a constrained direction, type a number and press Enter to place a point exactly that distance away.
Status Bar pills are interactive: Click ORTHO, POLAR, SNAP, or GSNAP at the bottom of the screen to toggle those modes on/off without leaving the keyboard.
