NC setting_ NC BASED ON MAIN PART NUMBERS_ISSUE

[kristjan]

Hi!

Having trouble with dxf files and the viewing direction of the element. Designed a stairway with plate stringers, steps as folded plates welded in between stringers. I need the attached parts contours on the dxf drawing. I know that I have ti choose the nc based on the main part numbers behavior. How is the view direction of the stringer plate (main part of the assembly) determined? The main part is marked in the isometric view of the stairway. When main part numbers is ticked, then it looks the plate from outside and not showing the contures. Pleas look at main part dxf and single part dxf to understand the difference.  How to solve the issue?

Ok, let's tackle the detail view direction first.  Select the item you want and type in detcs in the command line without hitting the enter key.  Four commands should show up.  if you choose show xxx it will show you the detailing direction for either the SP or MP depending on what you choose.  The other two options are to set the SP and MP detailing directions.  Try experimenting with this and see the effect it has on a detail drawing that is already created.  To get rid of the red UCS glyph that shows up, do a regen. (re on the command line.)

Now for the stringer issue.  Advance Steel does not differentiate numbering based on attached parts scribe lines.  This has been an ongoing issue for quite some time with lots of feedback/requests for the developers to fix the issue.

The work around I have come up with is as follows:

You need to differentiate the two stringers.  I assume they are geometrically identical.  To do this, double click on one of the two stringers, go to the User attributes field and select a user attribute and check the box.  Type in some unique identifier in the field to the right.

Do the exact same thing for the other stringer, except use a different unique identifier in the field. (Right hand Stringer)  Take heed of the note at the bottom of this page.  "Selected items will be used for numbering"  If the box is checked, the numbering process will look for whatever is in the field after the check box and compare to other identical parts.

Now re-number and you should get different SP numbers for each stringer even though they are geometrically identical.

Now when you dxf out the parts, you should be showing the scribe lines on the inside of each stringer.

(Make sure your NC based on Main Part Numbers is checked.)

If you are still having issues, attach your model file and I'll take a look at it for you.
