To activate the digitizer, choose the Managers>Devices
menu item. A dialog box appears allowing you to select the proper baud
rate and serial port. The default Baud Rate is generally the
proper one. In the Com Port section you can specify the COM port
attached to a serial socket on your PC. Confirm settings by pressing OK.
allows you to make the MicroScribe coordinate system
correspond to the world coordinate system of the
scene. To calibrate, choose the Tools>Digitizer>Calibrate
MicroScribe menu item. The program console will prompt you to
specify the following:
- Origin Point.
Pick a point on or near your physical model that will be the origin of
the MicroScribe coordinate system.
- X Axis. Pick a
point on or near your physical model that is on the X axis of the
MicroScribe coordinate system.
- Y Axis.
Pick a point on or near your physical model that is on the XY plane of
the MicroScribe coordinate system.
- Scale. Type the scale factor or confirm the default value. This
factor is applied directly to the points from MicroScribe obtaining a
different size for your physical model.
we are ready to use the Sketch on planes tool allowing you to
process the points from MicroScribe input and create point clouds
containing points that lie on parallel planes. As long as the command is
active you can press the MicroScribe button and send the position
solidThinking by moving the arm over the
physical model. If you need to change planes parameters or distances
parameter, release the MicroScribe button, set new parameters and press
the button again to start another section.
the Sketch on planes icon or choose the Tools>Digitizer>Sketch
on planes command.
The program console prompts
Origin, i.e. the
point defining the position of
the first plane.
In the Modeling Tool panel you can interactively modify other parameters.
This way it is easy to obtain the planar clouds which better describe the
original object shape.
Every time we press Create planes,
we create new planes
according to parameters. This way you can create planes with different
settings and steps. If you need to delete the just created group of
planes press Delete new planes.
The Snap to plane tol. parameter controls
the point distance to plane. If a point from MicroScribe has a distance
to a plane lower than this, the point will be projected onto the plain
and inserted in the plane cloud. This tolerance is very important for an
accurate model reproduction, but if it is too low, planes could not
intercept points sent from the MicroScribe.
The Min. dist. between points parameter
controls the minimum distance between points lying on the same plane.
When the distance from a projected MicroScribe point to other points on
the same plane is higher than this parameter, the point is inserted on
the plane cloud.
This tolerance is very important to control
imprecision due to manual use of MicroScribe and to create planar clouds
with a limited number of points. The higher this parameter, the
lower the number of points of the planar cloud.
Now we are can rebuild the surface.
Choose the Tools>PointsCloud>Curve from
PointsCloud menu item and create curves from the planar clouds
paying attention to the point representing the start of the curve.
If you want solidThinking allows you to reduce
the number of points of a surface given a specified tolerance. The
purpose is to simplify the surface while maintaining its shape in the
The Skin modeling tool allows you to create the surface using
We are finally ready to render our model.
