4 Simple But Effective Tips for the Hammer Editor

There is no such thing is the right way and the wrong way to make art in Valve's Hammer Editor, but there are definitely various practices that can save you time and frustration, 4 of which I am detailing in this post. If you have some tips that you find to be very useful please leave a comment explaining what it is.

Keyboard Shortcuts
These are just some of my favorite keyboard shortcuts. Learn and use these shortcuts and you will save yourself a lot of time while working in the editor.

• Control + m, transform
  
• Control + t, tie to entity
  
• Control + g, group
  
• Control + u, ungroup
  
• Control + e, center the view on the selected object
  

Additionally, mouse over the tool icons to learn their keyboard shortcuts

Grid Size 
Start working with the grid set rather large at first and then go small when needed. In other words, if you are creating the initial geometry for a huge building then use a larger grid to draw your object onto rather than a small grid. This will save you time in the long run by keeping your work neat and clean.

Multi-select
If you ever need to select multiple objects at once, rather than control clicking them one at a time, use the selection tool to draw over all of them, and then press enter to select everything inside your selection range.

Grouping
Group multiple objects together to better organize your work. For example, select all of the details inside of a room then turn them into a group (control + g) so that you can easily manipulate the group at once. If you ever need to edit one object within a group, rather than ungrouping the set you can instead switch to the selection type “solids” or “objects” (instead of “groups”) which makes it so only one select one object at a time.

What’s great about grouping in this editor is that you can group and group and group, multiple times, creating a multi-tiered grouping structure.  For example, I select object A and B and group them. Then I select my grouping of A and B, and select C, and group them. At this point, A, B, and C are all grouped together. Now, if I ungroup once then A and B will still be grouped together, as I only ungrouped one level. And if I ungroup one more time then A and B will be ungrouped from each other (we are now back to where we started).
