SketchUp (0,0) origin


#1

When importing contours from AutoCAD Civil 3D and you want to preserve drawing origin option when importing.
Can the SketchUp (0,0) origin then be reposition to the imported file and avoid the performance problems?


#2

FAIK no. SketchUp’s origin is fixed. You can only move the drawing origin.
Move the import to [0,0,0] or don’t preserve the origin when importing.


#3

maybe put a little marker geometry in the autocad drawing… then move everything with the marker being positioned at sketchup’s origin…

doing that, you’ll at least be able to go back and forth between the applications and line things up via the marker.

(and yes, i realize this isn’t your exact question to which the answer is no, you can’t move sketchup’s 0,0,0… i’m not sure of your exact workflow but i was just saying use the marker incase you need to take the sketchup file back into cad)

If you are trying to maintain the model’s Civil 3D origin but avoid the “Clipping” issue, you could do the following.

  1. Import the data with “preserve drawing origin” option checked

  2. go to a specific vertex in the imported data set (corner or end of a line)… let’s call this the “coordination point”. Determine the coordinates of this “coordination point”. The easy way is to use the Text tool as its default are coordinate values when placed on a vertex or Point. Record these coordinates.

  3. Select all the imported geometry

  4. Using the move tool, click on the “coordination point” and move your mouse to start the move action

  5. Using your keyboard, type “[ 0 , 0 , 0 ]”… enter. This will relocate your selection to the SketchUp origin.

Later … after finishing your modeling, you can move the geometry back to its original location by reversing the sequence . Instead of 0,0,0, use the original coordinates you recorded in step 2.

Make sense?

Yes, this sense. But again it would help if one could copy (the text coordinates) and paste them into the measurement’s field. This would avoid making mistakes and would increase the accuracy to six decimals without hassle.

To be accurate, move the entire selection an integer value X and an integer value Y as close as possible towards SketchUp’s origin. This would allow placing the selection back to its original position with “integer” coordinates.

p.s. and of course if great height is involved, also move the selection an integer value towards SketchUp’s origin.
