MODULE #4: SLA =============== directory: mod_04_sla/misc files: cust_view.cmd batch_sla.cmd test_pick_tol.cmd -------------------------------------------------------------------- This directory contains a file for setting the default view (cust_view.cmd), a file for experimenting with the pick tolerance for "attach near" operations, as well as a sample of using a batch file (batch_sla.cmd) to create a model and perform modeling tasks in a scripted way. The default view has: up_axis = Y_pos forward_axis = Z_pos The cust_view.cmd file changes these defaults to: up_axis = Z_pos forward_axis = Y_neg The default pick tolerance is hardcoded. There is an environment variable in v11.0 that you can use to change the value. You must set this variable prior to starting ADAMS/View. Below the default pick value is shown: On UNIX: setenv MDI_PICK_TOL 0.015 On NT: set MDI_PICK_TOL=0.015 The number indicates screen (pixel) coordinates, where the screen is considered 2 x 2 and the default pick region is of size 0.015. Using a larger value for the pick tolerance will increase the size of the pick area, the upper limit is 1 but you probably need not exceed 0.5. The batch_sla.cmd is provided as documented approach for the model development process. The instructor may want to use portions of the file to re-build the model up to a certain step if students are having problems and need to start over. Please note that "batch_sla.cmd" contains several references to other files, listed here: grep file batch_sla.cmd file command read file="../sla_start.cmd" file command read file="../utils/ctr_mar_on.cmd" file command read file="../utils/jnt_mar_on.cmd" file command read file="../utils/jnt_mar_toggle.cmd" As such, this model must reside in mod_04_sla directory if you want to import it. Also the referenced files must also exist in their specified directories. Therefore, you must assure the files are present or to change the path specifications in the batch file to suit your directory structure. Here is the general sequence of tasks that "batch_sla.cmd" performs: !#---import model, sla_start.cmd !#---PARAMETERIZE THE TIEROD GEOMETRY !#---turn on visibility of tierod cylinder marker !#---parameterize location of tierod_geo_base to pnt7_ref with F(x) tool !#---parameterize orientation of tierod_geo_base !# to pnt7_ref & pnt8_ref axis with F(theta) tool !#---move pnt7_ref around to test parametric behavior !#---parameterize length of tierod cylinder geometry with DM() !#---parameterize joint to pnt7_ref via F(x) tool !#---PARAMETERIZE THE UCA GEOMETRY !#---turn on visibility of all cylinder center_markers !#---create design point at pnt3_ref !#---create design point at pnt4_ref !#---parameterize orientation of 1st long cylinder with F(theta) tool !#---parameterize orientation of 2nd long cylinder with F(theta) tool !#---parameterize long cylinder lengths with DM() !#---parameterize short cylinder orientations with F(theta) tool !#---parameterize short cylinder locations with LOC_ALONG_LINE !#---turn on visibility of joint markers !#---use design point to parameterize UCA-to-spindle spherical joint !#---parameterize j-marker location for UCA_ground_rev !#---parameterize i-marker location for UCA_ground_rev !#---parameterize UCA_ground_rev j-marker orientation to lie in plane !#---parameterize UCA_ground_rev i-marker orientation !# by using F(theta) tool with Same As/Collapse options !#***alternate method of parameterizing UCA ref. joint orientation !#---define design variables and use for pnt7_ref location !#---create simulation script, transient 1sec/50steps !#---OPTIONAL: PARAMETERIZE THE LCA GEOMETRY !#---create design point at pnt1_ref !#---create design point at pnt2_ref !#---parameterize orientation of 1st long cylinder with F(theta) tool !#---parameterize orientation of 2nd long cylinder with F(theta) tool !#---parameterize long cylinder lengths with DM() !#---parameterize short cylinder orientations with F(theta) tool !#---parameterize short cylinder locations with LOC_ALONG_LINE !#---use design point to parameterize LCA-to-spindle spherical joint !#---parameterize LCA_ground_rev j-marker orientation to lie in plane !#---parameterize LCA_ground_rev i-marker orientation !# by using F(theta) tool with Same As/Collapse options !#***alternate method of parameterizing LCA rev. joint orientation !#---OPTIONAL: parameterize outline geometry !#---toggle the joint markers off !#---clear the select list
