"Sight" Survey (SS30)
Zoom All creates a huge workspace (drawing may disappear)
If a Zoom All (ZA) command causes your working drawing to shrink nearly or completely out of sight, you have some extraneous (and perhaps) erroneous data on the drawing that is causing the huge zoom window. To eliminate the bad data, you must first be able to find it. This is sometimes nearly impossible.
If you can still see your drawing, you could attempt to use the mouse to select (by rectangle) areas around your drawing from the image to the screen borders. If there are any extraneous elements in a selection area, they will be highlighted and you can simply press Delete to get rid of them.
More likely however, you will not be able to see your drawing. The easiest way to eliminate the bad drawing data is:
1. Select File > Save Job and SAVE your job.
2. Identify a point easily found in the drawing, and record its coordinate values.
3. ZOOM your drawing window so it contains all of the drawing parts you want to keep. (Probably using a Zoom Last (ZL), Zoom Page (ZP), or Zoom Window (ZW) command) Try Zoom Last first.
4. Select the drawing elements to keep by using the selection cursor and click on each element while holding down the Shift key.
5. Press [Shift] [Delete] (or use Edit > Cut) to delete the drawing. (Yes, this will delete what you want to save, but we’ll paste it back in a moment.)
6. Issue a DX command to completely erase the drawing. This will erase the bad data.
7. Press [Shift] [Insert] (or use Edit > Paste) to paste the drawing back into the window. When prompted for an insertion point, just pick an arbitrary location. Once the drawing is pasted back in the screen, all the drawing elements will still be selected. If they are not, select the drawing elements to keep by using the Selection Filter (SF) and clicking Select All.
8. In the Drawing Window, click Start > Modify > Move.
9. When asked for the point to move, click on the Zoom Window icon and zoom around the point you identified in step 2.
10. Click on the Grab All or Nearest Point selection cursor.
11. Place the cursor on the point identified in step 2, then left-click the mouse. This will select the point.
12. When prompted at the top of the Drawing Window for the “point to move to,” press the letter C (for coordinates) and a window will open for you to enter coordinate values. Enter the coordinates values separated by a space (either Northing Easting, or Easting Northing as indicated in the title bar of the prompt window) and click OK. Your drawing will move back to the proper coordinates. Click somewhere on the drawing screen to de-select the drawing.
13. Issue a Zoom All (ZA) command, and only the drawing you wanted should now appear in the window.
14. Select File > Save Job and save your job.
