Create a Sim

Affectionately known as CAS, this is where Sims are made. And you thought it was just WooHoo, didn't you?

The Sims
In The Sims, the CAS button is at the top of the screen. When clicking it, you will first go to the Family Bin. Click on one of the Family Bin panels to create a family. You are prompted to type the family name, though you can name it later. Click the top button in the right of the screen to create a sim. In The Sims, a CAS is very simple. It only contains age (adult/child), skin (light/medium/dark) and gender (male/female). The sim panel is very much simpler, since it is only built with heads and body. Unlike in The Sims 2, clothes cannot be chosen freely, since clothes and other accessories are one with the body, and the same goes for heads. Then you can type the name, bio and personality, and you are finished. You are unable to create a Family Tree in The Sims, because it is only determined by the Relationship between two sims. The heads and bodies contains skins for any age, including Elder, since there are only two life states in The Sims.

The Sims 2
In The Sims 2, the CAS button is revealed by clicking the family bin at the bottom of the screen. As opposed to The Sims, any age besides Baby or Young Adult (which must be made in the University CAS) may be created. Instead of having to choose from already finished faces attached to a corresponding hair, greater variety is possible with the new feature of being able to alter the facial structure (such as widen nose, thin lips, elongate chin etc.) and choose any hairstyle to go with it. Different eye colors and an additional skin tone is available for your Sims as well. If the Sim you are creating is older than a child, their Aspiration and Turn-ons/offs (Nightlife and further EPS) may be determined. Personality is set in basically the same manner as The Sims.

After several Sims are created, the family tree must be organized. All Toddlers, Children, and Teens must be related to at least one Adult member of the household. You can't link (using the family tree tool) a Child to Elder without an Adult in the family.

Click the 'Create a Sim' button and select 'Make a Child'. The two adults' DNA are inherited by the child and a child model is shown. If you don't like how this child turns out, you can click the 'Make a Child' button again.
 * 12) If you have Pets, you can create dogs or cats by clicking 'Create a Sim', then 'Create a Dog' or 'Create a Cat'.

Select the home you'd like them to move into (make sure it's outlined in green so your family can afford it) and then click 'Accept'. Now you can enter this new world...
