When the user creates two (similar) Beams/Profiles closer to each other (as shown in below image 1) and after that, if we delete one profile the connection from another profile will be deleted automatically (as shown in below image 2).
It is a feature in Tekla Structure to detect twins (similar) profiles applicable for all standard profiles available in the catalog. and the default range for detecting twin profiles for all standard profiles is set to 400mm.
If the user needs a different value to prevent this from happening set the lower value in the user attribute MAX_TWIN_SEARCH_DIST in the profile catalog with following below steps-
- On the File menu, click Catalogs > Profile catalog to open the Modify Profile Catalog dialog box.
- Select the desired profile in the profile tree.
- Go to the User attributes tab and set the property Twin profile detection distance to a larger value than 0, for example to 0.1.
- Click OK.
- Create the beams using the profile
Refer below the image where the default attribute value is shown for C Profile (C12.20.7)-
