What method to use a profile bank with impact modification in SolidWorks 2017?

Hello

Following my question about the configuration of an automatic update of the mechanically welded when modifying the "Lib Feat Part" profile. SLDLFP, I am asking for your help to guide us towards a new methodology (or not depending on what is possible).

What we want is to have a database of profiles (supplier or in-house) that we can use for the constitution of our 3D files and above all that any modification of the source file of profile impacts all the files in which it has been inserted.

My colleagues had gone for a bank of Lib Feat Parts for welded construction but the problem is that no update is possible other than manually.
I thought of a library sketch bank identical in a way to our current Lib Feat Parts that we could integrate into our files but I have never used this method so I don't know its limits or constraints except that the positioning and orientation is more delicate.

What do you think? Do you have any ideas?

Knowing that it must remain quite easy to use.

FYI, we are on SolidWorks SP5 / EPDM 2017 Pro and myCADservices/tools Premium.

Thanks in advance ;-)

I read your previous post. And I don't understand why you're making changes?

What is the nature of its changes?

The changes can be caused by multiple causes: a modified profile thickness, a real deformation requiring a change in the profile, a change in the position of the rib or crimp, etc.

And these changes can be caused internally or by our suppliers.

It doesn't necessarily happen very often, but it does happen and it is imperative that an update be made so that all our documents remain up to date.

Your problem is that SW's welded construction based on SW profiles is based on a notion of a sketch integrated into the prt file (which makes it autonomous).

To have the operation you describe, I only see the insertion of a part within the part, but you will lose some of the specific functionalities of mechanical welding.

Library sketches would have the same behavior as the Lib Feat part (no update)?

After that, we don't necessarily want specific mechanically welded features because we don't use them.

But how would the room within the room be updated? And we want to make full frames, so we would have to insert this piece 4 times?

Half agree with @stefbeno

To take up the message of @remrem: a standard construction profile does not evolve, it has been a standard for years now, and it will continue (IPE, IPN, UPE, etc...)

This question always comes up from time to time on the forum, the answers are always the same...

What you seem to be using looks like extruder profiles, so subject to rare updates.

Choice 1:

If necessary, only use "particular extruder profiles" (without IPN or UPN welded construction profiles, etc.)

Then the choice of ASM (with part mode option) with in PRT, will provide a quick job, and quick update.

(PRTs having length configs, and angle cut (if not manage in the ASM)

Advantage: designation of profiles in auto, with automatic update if necessary.

Disadvantage: management of corner cuts...

Choice 2:

"Lib Feat Part" having just a sketch, to be inserted in a PRT (with the option to keep the links), this mode is assimilated to a "small External Reference" (= performance food)

Allows you to work in duo with the "const.soudés" functions and to mix all that...

Advantage: allows you to update the sketch, if necessary

Disadvantage: the designation in a const.welded table will not be automatic.

Choice 3:

PRT in PRT = External Reference

food performance, if misused makes the pc slow down for not much, etc...

PRT in PRT ("medium or large" External Reference): yes insert several parts, or make body symmetries, or repetition.

Lib Feat Part of the "Feature palette" (maybe a set of functions, or just a sketch) but it has nothing to do with the Const.Soudés Profiles!!

we have a checkmark when inserting to keep or not the link ("small" External reference)

In the 2 cases above, the management options are in:

System Options / External Reference

The ASM mode (in room mode) is easier to manage, and less "resource food"

Choice 2 (sketch library) seems good to me because it takes up the imagined logic and works with our current Lib Feat Part sketch bank. It's the same as with the welded construction but we keep the link, it seems impeccable, I'm going to continue my tests.

I think there will be a problem of positioning because the sketch does not position itself in relation to its origin, on the right the sketch with the origin well aligned and on the left the sketch integrated into a room with offset from the origin:

In the Lib Feat Part sketch, there must be no coincidence on the origin (so sketch with a "-" in front)

Then, when we put down the sketch, there are in the panel:

Positioning / Editing the sketch

which allows, as its name suggests, to position it wherever you want...

11

Our Lib Feat Part sketches have all the fixed references so I don't have a "-" in front.

"Edit sketch" is only available if you don't check "Linked to library piece", which is what I want to do.

And even if I uncheck this option, I have this window that prevents me from doing anything :

Oh yes, I hadn't seen that the "positioning" was disappearing... as much for me

Otherwise, in the LFP, it creates 2 "References" (first folder at the top of the tree):

Plan / and Point

The plan must already be present,

To create the "point", you have to edit the sketch, and reposition a "coincidence" on the origin (or a line, or a point from another sketch)

That way, when we insert the LFP, he will ask for the plan, and the point.

I tried to add a coincident point at the origin (it does add to the references) but it is not taken into account when I click on this point, here is the image with at the top the selection of this reference point and at the bottom the passion of the sketch with this point in the middle of the section and not at the origin:

At home, no worries it works fine...

Opening the LFP file on its own, where is the coincident point?  screenshot if possible?

15

It is originally coincidence, here :

OK

and in the bottom half-image "bibliotheque_de_conception.jpg"

Where is the origin?

17

This is the point that is towards the center of the profile.

18

I have recompiled the images:

Top left: the Lib Feat starts with the desired origin;

Top right: the selection of this reference point;

Bottom: the positioning of the sketch with this point of origin placed (in the center) and not at the origin of the profile.

At home, it works...

maybe a bug specific to your PC, or in the definition of the LFP...

we must try to recreate the LFP and its references...

Otherwise see with the hotline support, at home it works.

Isn't it a "Dead Sketch" with only constants by chance??
