Whether it is possible to draw weldment profiles(SLDLFP File) other than (different section) default profiles in Solidworks?
Yes, the default location for the files are C:\Program Files\SolidWorks Corp\SolidWorks\data\weldment profiles. There you can open a file then alter it and save it as a new name. eg change angle iron 35x35x5 to 35x35x3. Or even make a new folder with custom shapes.
ASH is correct that modifing and existing file is the easiest way to get started. You can see and learn all the steps required to do it from scratch.
That's right ya, i want to know how to save the profile(different profile than default,like angle iron,etc).....
Produce a sketch of the profile (don't forgett to add 'points' for use with 'Locate Profile'). Save as 'Lib Feat Part (*.sldlfp)'.
I TRIED IT. BUT MADE SOME MISTAKE WHILE SAVING. PLEASE TELL HOW AND WHERE TO SAVE IT.
The place to put them is here:
C:\Program Files\SolidWorks Corp\SolidWorks\lang\english\weldment profiles
You should also create as many directory levels as the files already there as SolidWorks will look for them.
As mentioned above, use the 'Save as' command and select 'Lib Feat Part'.
