CIS/2 Export - No properties on beams

[Anonymous]

Hi All, 

We have been trying to export our AS2019 model into stp file as requested by customer. The model is numbered. The export was succesfull, however when imported into Naviworks all beams were shown like cuboids. 

After thais we attempted to create very simple model with two beams and 1 connections, tried to export it and import into Naviworks (with same cuboid result) and also import back into AS, where during the import the as asks us to specify what profile the beams are. It appears that the beams don't have any properties.

Please see the screenshots documenting the whole process step by step.

Simple 3D test model

Pressed 'Export CIS/2 button and confirmed this dialog

.STP imported into Naviswork

Importing stp back into AS

AS request a profile to be specified

Specified different beam to the original

Result

P1 - simple test model, 2x UB beams and connection

P2 - Export dialog after pressing @Anonymous to CIS/2' button

P3 - Exported STP imported into Navisworks

P4 - Import STP back into AS

P5 - Dialog jumps up and AS wants us to specify the profile for each of the two beams

P6 - Chosen random beam different to the original one

P7 - Result

Could anyone please advise what we are doing wrong? We haven't changed any setting in mapping. We have our database in our server so all our machine can access it, but import was tried in older version of AS2018 with local database and the result was exactly same. Going through Inventor or Autocad mechanical is not an option as our model is too big (exploded model 250Mb, IGES 1.2Gb)

We will be glad for any sugetions.

Thank you all in advance

Ondrej

The problem is maybe the definitions of export. What is the exact file format which is needed? 
Is it CIS/2 (which is very specific file format theme) or do you want STP/STEP? Please note, there's a big difference between the stp file from the CIS/2 export and the stp file which maybe come from Inventor.

I'm not sure if Navisworks really could open CIS/2 files, because this is as specific file format for steel detailling software (tekla and Advance steel for example).
But if you export a CIS/2 file and import this file again it should work correct.

I made some short tests and it work. here's a small video (I made no settings, so it looks not the best, but it show all parts correct): https://autode.sk/3acoIGB

Hi Sebastian, and thank you for your reply.

Our customer asked us for stp export but didn't specify for what software does he intend to use it.

We also thought that stp is something like iges. What would be the right way to export stp/step file from AS then?

Thank you

if you want to export step (which have the file extension *.stp, too) this is only possible by using 3rd part tools. Advance Steel could export *.sat files. Therefore you need the following steps:

• create a copy of your model
• in this copied model, delete all parts which are not necessary. like: connection boxes, modelviews, weldings..so all elements which could not be transfered to an 3D solid
• then select the part you want to export (or select all for exporting the whole model) and the right mouse button and in the context menu you will find "explode to acis". you could also use the AutoCAD "explode command"
• now you have solids and could export them with the normal export command and use the file extension .sat

The Autodesk knowledge is maybe a little bit short in this case: AKN

Great,

thank you very much for the advice.
