underfinished flange

[Per5]

Good morning to all,

I noticed that by making flange edges of a sheet metal part, the length of this fold remains underdefinite, in fact within the function you create a sketch not defined totally, to define it you should enter the sketch and quota it.
In this case, the fact that it is not defined, does it involve every time additional reconstruction and calculation times, or are they influential?


Thank you.

hi, in practice the flange is under defined i.e. it is not complete by quotas and/or constraints this means that you can not manage those flanges in a precise manner. It makes no sense to leave a sketch under defined above all for a design logic.

at the level of times of reconstruction and additional calculations could affect the slowing of sw in case the under defined parts begin to be numerous.

when making a flange of the edge you click on change flange profile *or change the sketch after doing the function.
* in case you use this method ignore the warning window, move it (not close it) and define the sketch; at this point click on end in the above screen.
subdefined sketches more than affecting reconstruction is a modeling error if you use a parametric cad. slowdown could be found if the underdefinite sketches were many (and would propend on several dozens) and especially complex. it is enough to make a performance currency to see the rebuilding time of the functions and decide whether to change modeling approach

default edge flanges are undefined sketches and managed by the parameter mask.
If you enter the flange sketch, you can change the shape, smell, quote and define it.
