Void Sweep Array doesn't want to work?

Anonymous — Fri, 19 Aug 2016 07:37:05 GMT

Hi Guys, i am trying to array a void sweep, i have put a parameter on the sweep path so that if ever i change the size of the plank, the "groove" will stay 30mm from both the top and bottom of the plank. When i go to array the groove, it loses its parameter. I have attached a couple of pictures, and help would be great.

Thanks in advance

By reading the error message, it seems that the constraint that you applied to the void at top and bottom are not constraining the shape of the void to reference planes but to edges of existing geometry. Remove those dimensions and do them again, but this time dimension to reference planes, not to edges of existing geometry.

Thank you for your reply, i have done that also, i constrained the profile to a reference plance, and then constrained the reference plane to the top of the plank, i still get the same problem?

Are you constraining the the path of the sweep? ie: edit sweep > edit path (and constrained the whole sweep here in edit mode ...to ref. planes)

No Access to a pc atm but I would assume that if the reference plane or the edge you are referencing to is outside the sweep, it would be considered outside the Group once you Array the sweep. My guess is that the reference plane you are constraining the length og the sweep to, has to be placed and lock in edit mode so it would Array with the sweep

Thanks for your reply, i have done it that way and i have also constrained
the sweep to a reference plane, and then also constrained the reference
plane. both ways do not seem to work.

Hi @Anonymous,

To constrain the array in a best way do them as a nested family, also nesting the family is a good practice for arraying voids.

It is hard to guess what the problem is without seeing the family. Please post it here, if that's possible.

For arrays, it is good to use a nested family. However, this does not work for voids if you simply create a void in a generic family. It needs to be a face based family with the void already cut in the face that is provided in the template. That type of family can be nested and arrayed. .

Hi, posted the family as requested. thank you...

I just think it was the way you set it out

As for arraying a void across the surface of a solid is beyond me

Hmm... sorry, I don't have the 2017 version in this computer.

I changed the void to a nested family.

Hello everyone

Sorry for reviving this thread but creating an array of a void in a family with editable height and width peaked my interest

After some research I found out I had to create a line based family and using Alfredos tip of using a face based family with a void cut into it and nesting it into the family.

However when i try to array it, it doesnt seem to want to array in the right direction. Could anyone take a look at it?
