Buggy Ordinate Dimension Functionality in Drawing Workspace?

[alexpinson5]

Hi all,

I've been fighting some odd functionality using the Ordinate Dimension tool when creating drawings. I often use this to dimension hole locations on the fixture plates we manufacture. Basically, when I try to dimension to a center mark placed on a hole there's about a 25% chance that the dimension fails giving the (!) warning symbol and making me reassociate the dimension. It seems that if the snap location appears as a circle the dimension will be successful, but if it appears as an 'X' it will (sometimes) fail. Sometimes it works fine even with the 'X' snap.

Here is a screencast of my issue: https://somup.com/c0noDTxPCk 

You can see how sporadic the issue is, but the best example of the issue happens around the 1:00 mark. You can see how difficult it can be to get the circular snap at times when trying to reassociate and fix the dimension, and it can be a huge time sink when creating drawings. Am I doing something wrong? I could always dimension before placing the center marks but IMO it shouldn't matter.

Hi @alexpinson5 

I'm sorry to hear that you are having trouble. Please share a downloadable link to your drawing, so that I can ask the team to take a look at this for you, or if it is sensitive, feel free to send it directly to me Clint. Brown {a} Autodesk.com

Something that you try in the meantime, is to use the Snaps (on the right click), this will let you specify the centre of the hole. Bonus Tip, is that if you place the Zero dimension, you can then use the chain dimension command, and it will line up the ordinate dims automatically for you.

Hey Clint - thanks for the tips. Makes my life easier, even if it doesn't completely solve the original issue.

Here's a link to a copy of the drawing: https://a360.co/3Sc6jAf although FWIW this happens on every drawing I make of each of the plates we sell. It's not isolated to this file.

Hi @alexpinson5 

Thanks for bringing this to our attention, the team has taken a look and can reproduce this behaviour. The technical reason, is that the dimension is snapping to the intersection of a centreline and an existing dimension extension line.

We've logged a ticket to investigate a fix, our internal reference is FDWG-16264
