Blocks within a flip block show reversed

OceanaPolynom — Sun, 24 Jun 2018 08:17:23 GMT

Hello

I have a block that consists of a pline and some other small blocks (see New Blocks.dwg). The block can be flipped in 2 directions, around the x axis and around the y axis. When the block is flipped around the y axis everything is ok (see Right Way.jpg). When the block is flipped around the x axis, the smaller blocks are reversed (see Wrong Way.jpg) I am not sure if this is a AutoCad issue, or it maybe that a VBA solution is required.

Thank you

John

Hi,

>> I am not sure if this is a AutoCad issue <<

Yes .. it's a AutoCAD issue that can not be fixed when you use mirror command as used in Wrong Way.jpg . you have to make another separate situation blocks for flipping around the x axis . i suggest to read this AKN that describe it well here . >> Click <<

Regards,

Is there a difference between flipping a dynamic lock and using the MIRROR command?

Your blocks need editing. More specifically, you need to be aware of the properties of the attributes within the block because the properties will affect how an attribute will behave. Generally, your blocks are composed of two things: 1) line work and 2) attributes. The line work is fine but the attributes are not.

You have three blocks:: ng, m- and AL:0. Click on an individual block, such as ng. right click and select block editor. In bock editor, click on "B" and in the properties palette scroll to Misc. This is what you'll see.

Block Editor/Properties palette/Misc section.

You'll need to look at, and edit, each attribute, in all three of your blocks to correct your backwards text that occur when you 'flip' them.

Also type MIRRTEXT on command line. Options are 0 and 1. 0=text retains reading direction. 1=text turns backwards. The MIRRTEXT variable you choose will affect the block's behavior.

Hello
When I flip the large block around the x axis the attribute text in the
small blocks is not backwards, rather the locations of the attributes are
reversed. The letter is now on the bottom and the number appears in the
top location. The fact that the text letter is Hebrew may be confusing.
The small blocks are being mirrored about the x axis, but the text is not
backwards.
Thanks very much.

I remember a thread with someone having issue with Hebrew text mixed with a left to right text and how it was justified. If I remember one of the suggested solutions was to make visibility states instead of using flip. A little more work to set up, but if you can't get it working correctly it's another option.

Ok, I used attributes instead of text to solve part of my problem. This is coming up now for the same reason a lot of others are coming up against this: I am working on plans for a duplex where one unit is a mirror of the other. Of course it makes sense to use blocks, because if I update one side, it automatically updates the other. To try to maintain left and right versions that are independent is just asking for errors to creep in.

The next, related question is what about dimensions? I have some blocks that have dimensions in them. I have a couple of handles in the blocks so you can lengthen or shorten various aspects of the block, and the integral dimension stays updated. However, when that block is incorporated into a bigger block that then gets flipped, the dimensions are now backwards. How can I get around this? If I can't fix the orientation of the text part of the dimension, is there a way to feed an attribute the contents of a hidden dimension or something so I can fake a dimension line where the text part of it stays oriented?

Also, people have mentioned putting flip attributes into the nested blocks. I am not seeing how that helps unless you explode the containing block after you flip it, which I definitely do not want to do. I can't access the nested blocks' flip handles. Am I missing something?
