SELECTING MULTIPLE POLYLINE SOLIDS AND CUTTING THEM

Recommended Posts

     1. Is there a way to select multiple polyline solids at one time? This should be a no brainer (or I'm having a "senior" moment). I had to make a custom lattice panel. I decided to make it out of p-solids. In the process of making the unit I realized I could not select all the p-solids at one time, but had to select each individual p-solid one at a time. Am I missing something? If I'm not then this is another thing CA needs to add to the never ending list in revamping there cad tools. Maybe I just need more coffee.:)

     2. The process I used was to make p-solid 3/8"x1.5" and lengths of 8' and 3" spacing between them set at 45 degrees. I then did the same at 45 degrees the other direction and in front of the first angled section. This gave me the "basic" lattice panel. I then made another p-solid with a custom cutout in the center with the shape I was after. I then coped it and took this p-solid and placed it over my lattice panel for a "subtraction". When I did the "subtraction" it would only cut the p-solids going in one direction. I then made another copy of my custom shaped p-solid, overlaid it onto the lattice panel and did a "subtraction" with the opposite angled p-solids that did not cut with my first subtraction effort. They would not cut. I tried many times using various  p-solids to do a "subtraction" but could never get the second set of angled p-solids to cut. Is this also a bug or am I going abut this all wrong? Is this the usual process in making a custom lattice panel? I know there are lattice panels in the library but they were just too small for what I wanted to show. I know this is plenty "wordy", but I hope you can get an understanding of what I did.

     Thanks to all in advance for your time and advice. It's always very much appreciated.

P-solids are odd to work with many times, I believe.

 

I created the lattice as you did, then unioned all the parts together and converted to a Solid.

 

Created a mask from a p-solid with a hole shaped and sized to the lattice I wanted. Converted it to a Solid.

 

Then did a Solid subtraction.

Polyline solids have had some buggy behavior in the past.  Some of it has been fixed but maybe you found a situation that is still not behaving properly.  Probably a good idea to send in to tech support detailing EXACTLY what you did to create the second group.  

 

On a side note though...Are you sure you actually used Polyline solids for the second group?  Is it possible you used a slab, box, or some other object?

 

Anyway, I would probably personally do as Eric suggested and just convert to a solid.  A lot more possibilities that way anyway.

I tested it' easily repeatable.

Mark...................I will use your solution the next time. It seems like the best way to get the job done.

 

Michael................Yes, positive they were p-solids. I made the second group by copying and the reversing the first group. I do believe it's a bug and will report it.

 

Thanks to both of you for your time and advice. Have a great day.

Yup.  This is likely the source of your problem.  I'm away from my computer right now but until the problem is fixed I would try these potential temporary solutions...

 

-Reflect in plan view instead of the elevation view.

 

OR

 

After the initial left to right reflect, try to reflect again in a plan view but this time in the top to bottom direction.

 

OR

 

After the initial reflect, convert back to a plain polyline and then convert to a polyline solid from that.  

 

I know...all workaround solutions but they might just help keep you moving forward at least.
