3D Dimensioning Glitch

[Scroto_T_Baggins]

Hello,

 

When I add dimensions to an 3d object in an isometric (or similar) view, the dimension lines get placed way off screen, and the leader lines are projected onto the x-y plane.

 

Additionally, when I try to add lines to an object that is far from the x-y plane, the mouse position responds to the line's location as if it were drawing on the x-y plane.

 

Do I have to continually make custom UCS coordinates just to draw in 3d without hassle? There are other times when this does not happen (perhaps only when my 3d object is very near the x-y plane...

 

Thanks,

Maybe all you need to do is reorient your UCS and/or change its origin. I've never had to make custom UCS coordinates to draw anything in 3D.

I always dimension in paper space with 3D. Sometimes you will have to manually enter dimensions... but not usually. It works WAY better and you don't have to worry about the dimensions being in iso.

Turns out that I need to move my x-y plane origin to be coincident to the object. All of the lines and dimensions that are not snapped to any particular object (including how dimensions are handled) are projected onto the x-y plane.

 

Thanks

So you are good to go? Problem solved?

Mr. Baggins,

 

It sounds like you've got things ironed out. Yes, you do need to adjust your UCS to place dimensions onto the plane you need. No need to create or save a UCS, just pick the 3 point option. AutoCAD will always place dimension on the current x-y plane at a z- value of zero. I'm not sure how things work for this in paper space as resullins suggests, I dimension in model space.

 

If you are familiar with lisp programs I've got a little program called AutoUCS.lsp you can download from my website that makes it really easy to manipulate the UCS. There is a little video to see how it can be used.

I dimension in my layout but I avoid dimensioning 3D objects. I dimension the extracted 2D views instead.

Thanks Patrick, I hope your routine works on acad2000, I've learned not to turn up my nose to a lisp routine :wink:

 

I usually dimension in 2d when it comes to making plots for the machinists, but my situation is just for measuring a particular dimension on the model. Perhaps I should get used to using a measure command as opposed to a dimension command.

 

...And that about solves it ReMark

 

Thanks everyone, I look forward to contributing to the community

 

cheers

It should work on ac2000 but please let me know if it works one way or the other - it works quit a bit differently then the way users are accustomed to. I've been thinking about combining the AutoUCS.lsp to an auto dimensioning routine that I have that would make things super fast to dimension 3d solids in an isometric view.

 

I don't do a lot of dimensioning in 3d but I can see that many do and it could be useful.
