Surface Cut/Trim

Surface Cut/Trim

Surface Cut/Trim

(OP)
Does anyone know if you can cut multiple surfaces with one cut feature? I'm using WF2 and it only lets me cut one surface at a time. My entire model is a surface model going to be used for CFD analysis and only half the model is needed. It will take me all week trying to cut this model in half if I have to make a cut for each surface feature.

Any suggustions?

RE: Surface Cut/Trim

Is your surface model an imported one? (came from a step/iges file)
If yes, you need to go
Edit Defifinition->Edit->Feature Properties->and check the Join surfaces box
So that the surface model is made of 1 quilt.

RE: Surface Cut/Trim

All I can think of is to use a single sketch to define the cut, and then create a mapkey that has you to pick the surface features to be cut using the same sketch, then repeat ad nauseum.

AFAIK unless you've got solids, it won't work in a single surface trim, unless you can somehow merge every surface together (you likely don't want to do that either).

I tried joining the surfaces, but given how complicated the geometry is the joining failed.

I then tried the mapkey idea and that did cut down on the time required to do it. It only took me a few hours to have the model cut in half.

Thanks for both your suggestions.

RE: Surface Cut/Trim

(OP)
I found an interesting way of getting the model to be one quilt without having to join the surfaces. You can take your initial model and create an IGES model, but when you create the iges file select the OPTIONS button on the pop-up IGES window. It will ask you to enter a file name. This file will be stored in your local scratch and be called something like iges_config.pro The file will contain the following:

Iges_out_all_srfs_as 128
Iges_out_spl_crvs_as_126 YES
Iges_out_spl_srfs_as_128 YES
Iges_out_trim_xyz YES
Iges_out_mil_d_28000 NO
Iges_out_trm_srfs_as_143 NO
Iges_out_JAMAIS_compliant NO
Iges_out_trim_curve_deviation DEFAULT
Intf3d_out_extend_surface No

When you generate the iges model now the model will be all one quilt. I'm not sure why, but I wish my fellow co-workers would have showed me this earlier...

RE: Surface Cut/Trim

How about if you were to make a solid protuson from each surface and then make the cut.

Or create an envelope part and make the cut after.

Just some ideas after the fact.

RE: Surface Cut/Trim

You could also create a neutral file that way you can keep all your datum planes and it will be one entity.
