Using 'Convert to Solid' Object in Matlab Livelink: specifying a selection

Please login with a confirmed email address before reporting spam

I am scripting a simulation using the Matlab Livelink interface. I am able to build a geometry using and import object surface combined with parametric surfaces and I would like to convert this into a solid object.

I have already tested this through the GUI and it works fine. The geometry generated through the script also looks fine (i.e. edges match up).

However the problem is how to "feed" a selection to the convert to solid object:

          csol1 = geom1.feature.create('csol1','ConvertToSolid');

I can see that there is nothing selected when I type the following command in Matlab: csol1.selection('input')

I figured it out.

I created a Cumulative selection as follows and then added the constituent geometric entities to it:

geom1.selection.create('sel1','CumulativeSelection');
imp1.set('contributeto','sel1');
pback.set('contributeto','sel1');
pforward.set('contributeto','sel1');
pbottom.set('contributeto','sel1');
pleft.set('contributeto','sel1');
pright.set('contributeto','sel1');

Then I created the ConvertToSolid object and assigned the selection to the input of csol1 as follows:

csol1 = geom1.feature.create('csol1','ConvertToSolid');
csol1.selection('input').named('sel1');

I know this works because I am now getting some topology error during the convert to solid operation. Progress.

I fixed the topology error by setting the 'repairtoltype' property on csol1 to 'auto'.
