I found all format to import with Alibre let me know which format i should
order to match Alibre and Rino
Import data from other CAD systems
Importing STEP data
Importing IGES data
Importing SAT data
Importing DXF/DWG data
Import Analysis and Reporting
Alibre Design's interoperability solution provides flexibility in
importing
data created in other CAD packages. Alibre Design supports the import of
3D data in STEP, SAT and IGES formats
2D data in DXF and DWG formats.
Data may be imported into Alibre Design from the Home window or from open
workspaces.
From the Filemenu, select Import.
In the Import File dialog, select the file to import. The Import File
Options
dialog appears.
Determining which import options to select depends primarily on the format
of
the file to be imported and its intended use in Alibre Design.
Importing STEP Data
Most STEP data consists of solid model data. Typically, the Stitch to
Solidoption should be selected for STEP data import.
Depending on the originating CAD application, exporting STEP data could
result in varying levels of inaccuracy. If problems are encountered, the
Healoption may also be used to improve import success as well as improve
the
quality of the model in Alibre Design.
The Make Tolerantoption may be used in situations where known inaccuracies
occur to enhance the ability to perform modeling operations on the
imported
file.

Importing IGES Data
Most IGES data consists of surface data. Selecting import options for IGES
files depends heavily on the intended use of the data in Alibre Design
after
import.
The Unstitch to Standalone Faces option can be selected if the primary use
of
the file will involve only visualization in Alibre Design. Measurements
may
still be taken on the model, but modeling operations may be unsuccessful.
The Stitch to Solid option should be used if modeling operations will be
performed on the file. The Heal and Make Tolerantoptions may enhance the
quality of the imported model and the ability to modify the model through
modeling operations.

Importing SAT Data
SAT Data could consist of both solid data as well as surface data.
Consequently, selecting import options for SAT files depends heavily on
the
intended use of the data in Alibre Design after import.
Typically, the Convert to Solid Modeloption should be selected for import.
The Healoption may be used to improve import success for files containing
known inaccuracies. The Make Tolerantoption may also enhance the ability
to
modify the imported file.
For all three formats (STEP, IGES, SAT), the Discard Non-Solid Facesoption
may be used to import files that have irregular surfaces associated with
the
model. For example, many models are created using various types of
reference
geometry. The Discard Non-Solid Facesoption will essentially remove
non-solid
faces or reference geometry on import.

Importing DXF/DWG Data
The Import Options are not necessary in importing 2D data.

Import Analysis and Reporting
Alibre Design provides import analysis and reporting tools as aids in
importing data.
The Alibre Design Import Advisoranalyzes the success of the import,
reports
any import problems, checks the part for inaccuracies, and recommends
settings to use to improve the import success. A Healing Analysis report
is
also included if the Healing option is selected.
Check Part, Healing Analysis, Conversion Logcan be used independently from
the Import Advisor.

Rhino can import iges and step or stp.
Paul Lamar from Germany
OK PAUL I PURCHASE THE DESIGN AND HE WILL SHIP ON 3 FORMATS,*3DM ,OBJ,DXF
Jean Prudhomme
3dm is native Rhino. That is great.
I wont be able to work on it until I get back
as I don't have a windows computer with me.
I am not completely sure but I think 5/8 scale might be better
than 3/4 scale. I'll have to work out these details.
George Grimes is up to speed on Rhino so I will send him the .3dm
and see what he comes up with at 5/8 scale. Things like wheel
diameter, prop diameter and cabin height are critical when
scaling.

i SHOULD RECEIVED IT IN FEW DAYS FROM ALASKA

Probably too big to email so you may have to mail a copy
on DVD to George

Paul and Jean, Scaling the 3Dm surface model is a single command operation
if you are scaling to the same scale.I looked up a few Piaggio designs and
found the listed airfoil as a NACA 23012 at the root and a 4412 at the tip
on both the main wing and the stabilizer and a NACA M-12 on their P7
series. You may want to leave the wing scaled down less than the fusaloge.
Hopefully the DXF files will have the airfoil elements plotted with
the flap amd aleiron % of chord, if not the ordinates can be downloaded. I
search ae.illinois.edu canard airfoils and use the reverse
directory to find out what is used on airframes of similar designs, then the
main list for the ordinates. Personally I like the Harry Riblett airfoils
on the main wing, and Rontz on the canard.
Have you got any idea what prop clearance you need at the rotation
point on take off. I am thinking at the stall angle of attack of the
canard something like 8" clearance. It is not as much angle as it seems
since the incidece on the canard has 3 degrees more incidence The full size
version has five blade props so you will likely need a minimum of three
blades with one RH and one LH to get the disk diameter scaled down to a
workable size.
We will need to know if the CNC foam cutting shop wants the airframe
sliced into workable size pieces or would want it as a complete solid that
he can devide up at his location. As I remember the depth of the machine
accomodates 20" deep sections and the width and length are something like 5
feet by 20 feet
When you start looking for Glass cloth you might want to call
Steve Thayer at thayercraft.com in High Point NC. I get 73 inch wide from
him which reduces the number of seams. He has 3 million yards on hand and
probably that much more lost to the inventory system. They ride bicycles to
check stock quantities. He is building a Cozy and flies a Cessna 175
