Languages and Strings
1) Consider the language L = cfw_1n2n : n > 0. Is the string 122 in L?
2) Let L1 = cfw_anbn : n > 0. Let L2 = cfw_cn : n > 0. For each of the following strings, state

Model
Process
The figure starts in
the most
convenient plane,
in this case the
right plane was the
chosen for the
extruction.
Once it has been
extruded the next
step is to work on
the rails by
creating a new
plane in the 45degree direction.

Design Process
One of the objectives of modelling is to capture the design intents thus the design
changes can be made easily or modifying a few dimensions. It is important to plan the
steps in terms of the types of features, the sketch profiles, relation
