This is a list for the commands used over this block.
_cp
controls de construction plane aka coordinate system, inside of this command you can:
place a new origin for the cp (default)
rotate along any axis or the X Y and Z axis a specified number of degrees
aling the cp through 3points
set it back to the original universal position
_line
you can draw a line between two points by
specifying the points directly: _line > 0,0,0 > 1,1,1
or between two existing points making sure that the point snap is on
_point
you can draw a point by its coordinates entering X.X,Y.Y,Z.Z separated by comas and using a point (.) as decimal sign
_move
you can move objects by specifying an origin or star point of displacement and an end point, you can define the movement graphically or just enter the coordinates
_copy
copy is a submode of move, instead of moving the selected object you just create a copy of it at the destination point
_trim
trim is a very useful command, it cuts undesired geometry by other present geometry. Trim works as follows:
You define the set of cutting objetcs, those tha will act as scissors for your geometry.
Then you define the goemetry you want to cut, take into account that depending on the side you pick, you will keep one solution or another.
_fillet
fillet draws arc curves between two given curves, you can define a radius which can be set to zero in order to get a corner
_mirror
mirror creates a symmetric copy of selected geometry defined by a symmetry line, you can choose to delete origin geometry or not
_scale
scale returns a resized version of geometry after applying a linear scale transformation, you have to define an origin point and a scale factor, defined by the ratio between two segments or by a numeric value.
_intersect
this command is useful for Exercise 3. It determines the intersection of selected geometry so, if you enter lines and a crossing plane you will get a set of points.
_SrfPt
we can use this command to define surfaces from 3 or 4 points, it is not compulsory that those 4 points are coplanar but by the momento we will stick to simple planar surfaces
_PlanarSrf
PlanarSrf creates a planar trimmed surface out of a closed 2d polycurve or polyline so we can use it to define the faces of our models
Give all the commands a try and follow the instructions on the command line!!
