Auto dimension objects within polyline to polyline edge on x axis


Recommended Posts

Posted

Hi helpful people :)

 

Does anyone know if there is an easy way to auto-dimension as per attached image, by selecting the polyline & circles in one hit? I have thousands of these to do and the amount of time it takes to put a linear dimension on each hole is crazy!

I've tried qdim but it doesnt give me what i'm after.

 

Thanks in advance,

Claire :)

I just have one question have you made the posted image to be a 3d view ? so dims are vertical ?

 

To dim all the circles horizontally would be pretty easy just make a false line that extends past the pline shape draw horizontal and just dim the left intersecting point with the centre the right and center, please confirm about 3d. Oh it is easy to find the circles (ssget "wp" ....

Hey bigal, 

No it’s not 3D, that’s the shape in 2d. 

I was hoping to find something similar to qdim where it automatically dims them all at once, I can do them as you said but I have thousands of them & it’s super time consuming!

How are the plines orientated, are they always 4 sided polygons and are the dims always aligned as shown?

OK, No answer to the above so I've assumed they all look like the above.

 

Try the attached (Updated). It is cobbled together from different routines, works (minimally tested) but you need to have the correct dimstyle set as current. I have assume the placement point for the dims to be 3 units up (y axis) from the centre of the circle. It looks correct but may need adjusting. Selection is (ssget), don't select too many groups at a time as it will slow down considerably

Dlanorh, this is perfect, you are amazing!

 

Yes they all look and are dimensioned exactly the same as that first pic just slight variations in sizing.

 

This has saved me so many hours & a lot of frustration.

 

Thankyou,

Claire :)

I have again updated the file attached above. I have indicated where you can change the dimension positioning, and speeded the code up a bit by removing dimensioned circles from the list.

Sweet, got it!

Again, thankyou so much :) :) :)

Leaving my attempt just for the record (works with circles only) -
