Creating a surface with a sketch using Abaqus Python -

-

my question might sounds rather simple knowledge in abaqus scripting inexistent. aim represent set of polygons in same part each polygon represents 2d surface (in 3d space) of part. creating script generate sketch each polygon (not sure if best approach). creating surface foreach of sketches.

how achieve this?

many thanks!

the code:

from abaqus import * abaqusconstants import * import sketch import part  mymodel=mdb.model(name='model-1')   #-------------first polygon-------------------------------  s1=mymodel.constrainedsketch(name='__poly0__', sheetsize=100)  g, v, d, c = s1.geometry, s1.vertices, s1.dimensions, s1.constraints  s1.line(point1=(10.0, 10.0), point2=(10.0, 15.0)) s1.line(point1=(10.0, 15.0), point2=(-10.0, 15.0)) s1.line(point1=(-10.0, 15.0), point2=(-10.0, -15.0)) s1.line(point1=(-10.0, -15.0), point2=(10.0, -15.0)) s1.line(point1=(10.0, -15.0), point2=(10.0, -10.0)) s1.line(point1=(10.0, -10.0), point2=(5, 0)) s1.line(point1=(5, 0), point2=(10.0, 10.0))  #-------------second polygon------------------------------- s2=mymodel.constrainedsketch(name='__poly1__', sheetsize=100)  g, v, d, c = s2.geometry, s2.vertices, s2.dimensions, s2.constraints  s2.line(point1=(10.0, 10.0), point2=(5, 0)) s2.line(point1=(5, 0), point2=(10.0, -10.0)) s2.line(point1=(10.0, -10.0), point2=(10.0, -15.0)) s2.line(point1=(10.0, -15.0), point2=(15.0, -15.0)) s2.line(point1=(15.0, -15.0), point2=(15.0, 0.0)) s2.line(point1=(15.0, 0.0), point2=(10, 10))  #----------one part 2 planar faces (one per polygon)----- p = mdb.models['model-1'].part(name='part-1', dimensionality=three_d,type=deformable_body) p = mdb.models['model-1'].parts['part-1']  #how can put 2 planar faces here?  #first polygon #p.baseshell(sketch=s1) #del mdb.models['model-1'].sketches['__poly0__']  #second polygon #p.baseshell(sketch=s2) #del mdb.models['model-1'].sketches['__poly1__']  #-------------------------------------------------------------

surface can mean 2 things. in abaqus terminology surface reference face or edge of part or assembly. doesn't mean flat part. out side of abaqus, creating surface taken mean creating planar part.

here code yours makes part in 3d space (a 2d part have edges in sense of abaqus surfaces). creates abaqus surface on 1 of 2 faces. 

from abaqus import * abaqusconstants import *  s1 = mdb.models['model-1'].constrainedsketch(name='__profile__',sheetsize=200.0) g, v, d, c = s1.geometry, s1.vertices, s1.dimensions, s1.constraints s1.line(point1=(-21.25, 22.5), point2=(-33.75, -20.0)) s1.line(point1=(-33.75, -20.0), point2=(-3.75, -32.5)) s1.line(point1=(-3.75, -32.5), point2=(40.0, -25.0)) s1.line(point1=(40.0, -25.0), point2=(25.0, 25.0)) s1.line(point1=(25.0, 25.0), point2=(-21.25, 22.5))  #this creates actual part - planar surface exists in 3d space p = mdb.models['model-1'].part(name='part-2', dimensionality=three_d,type=deformable_body)  p = mdb.models['model-1'].parts['part-2']  p.baseshell(sketch=s1) del mdb.models['model-1'].sketches['__profile__']   #the following finds , creates "surface" on part.  f = p.faces face=f.findat(coordinates=(0.0,0.0,0.0)) face_ind=face.index side1faces=f[face_ind:face_ind+1]  p.surface(side1faces=side1faces, name='surf-1')

if isn't question asked, please explain more in question.

i'm using unity3d networked multiplayer online game have large complex 3d terrain scene forest, trees, cliff, hills, mountains, bounders, etc. players can build structures sort of minecraft, , put them anywhere in scene, or move them around anytime. aside human controlled players, there automated ai players , objects animals roaming around scene following path. the problem how make these automated ai players , animals, able navigate around static , dynamic player created structures, because path follow can blocked player created structures, or other players , other ai objects, cliffs etc. have find away around them or on track if tumble down off high cliff example. so made navmesh , used navagents, takes care of static, non moving objects, how make ai players navigate around each other , dynamic structures created players can number in hundreds? i thought of adding navmeshobstacle everything, result in being attached hundreds of objects since user created structures b...
