AutoCAD Civil 3D

[#1]

Title pretty much sums it up. When I do zoom extents it zooms out so far and it takes me forever to zoom in and find my drawing again. This happens even if I select all and delete everything and then draw a circle at the origin so I know I don't have any fragments somewhere out in the drawing. Help please!

hi
Any chance that limits might be affecting the file? I'm a relatively new user so take my advice lightly. But I recall from way back in the day that limits settings could give you that behavior.

I had considered that also but changing the limits doesn't seem to help the problem. Thanks for trying.

Something is out there. Post the file after you have erased everything and
maybe we can find the problem.

Also try selecting all of the objects in the drawing and then using the wheel to zoom out a little (in case you have a toolbar covering part of the screen) and you should be able to find the trouble object, well sometimes not. The grips make small objects easier to see.

Here is the offending file hopefully somebody can beat it into submission. There is nothing in it except one circle at 0,0 with a radius of 100.

After auditing, deleting the layouts and your 100' circle, purging and
selecting all, I get 14 objects in the file. 13 are in model space. There
are eight blocks that cannot be purged. I am guessing your problem has
something to with these blocks. Have tried several things, but cannot find
them even though I can select the 13 objects. I tried to erase the 13
objects, but they are still there after the erase. I tried listing them but
nothing came up other than 13 objects. The audit did find errors. I would
try wblocking to a new file and starting over or going to a backup from
before the problem started.

13 of the objects are the PointGroups and don't have any effect on the
Extents. There are 3 objects of the type "AcMapBulkFeature". Deleting these
via ActiveX lisp fixed the problem.

Here's the quick lisp I used. Note that I have no idea WHAT the BulkFeature
objects are or what they may be doing. It doesn't appear to make this
drawing unstable, but make sure you have a good back-up of the drawing
before using it.

(defun c:deletebulk ()
(vl-load-com)
(vlax-for ent
(vla-get-modelspace
(vla-get-activedocument
(vlax-get-acad-object)))
(if (eq (vla-get-objectname ent) "AcMapBulkFeature")
(vla-delete ent)
)
)
(princ)
)

When I get tired of looking for the problem I set the zoom limits to my drawing and then use "zoom limits" (zl) instead of "zoom extents".

[#10]

Draw a line from a snap point on one of the objects in the drawing to 0,0,0. Select all objects (including the new line) and hit ctrl + C. Open a new file and hit ctrl "v" and paste anywhere in the drawing. Select all and move the pasted objects by selecting the 0,0,0 point of the line as the Base point, with the second point 0,0,0. Now delete the line and try zoom extents.
