[Enhancing polar/linear array] : option "intances to be skipped"

Post by Piero69 » Tue Aug 18, 2020 7:27 am

I feel useful an option in the polar and linear array to skip some istances in the feature.

ie: i have to make 7 holes (8 holes to 45° but one), i make the polar pattern and then select graphically the ones to be skipped

what do you think?

Have a look at the Lattice workbench.
You need at least FreeCAD 0.19.23300 to edit my current sketches.

BIG +1 on that. There were allot of times that I needed that.

Would be great to have the option to skip instances with tha pattern.
@Chrisb It is nice that Lattice have that option, but it second (or third )best ;)

It looks to me as an excellent challenge for one that want to start contributing FreeCAD. Let's go guys. Not anymore time to request. Roll up your sleeves and start coding. ;)

Isn't Part->Defeaturing what you are looking for?

Flange with a polar pattern of five holes, one of them "defeatured":

The pattern will lose its parametrics, but that is probably to be expected?

I havent tried myself, but I read in the German forum that Defeaturing workbench keeps parametrics.

Hi,

Just as an Idea ... how about a kind of user definable "Pattern" like it might be known from "regular expressions" which is repeated till the count of instances is reached.

e.g. "YNYNN*" ... leads to: Feature, No Feature, Feature, 2x No Feature and will be repeated ... till ...

Regards,
Stefan

Please watch my golfball video:

From the Lattice2 Workbench I use the tool explode Compound to split an array into its individual parts, everything else you can see in the video.

Best regards
