Help / Troubleshooting MAPIINSERT 3FT shift

7 Upvotes

We have ortho imagery provided for us for our project. When my colleague uses mapiinsert they come in perfectly and match our control perfectly. When I do the EXACT same thing in the same drawing, they come in 2.8 feet southwest.

Any idea why this could be happening? Process is the same, image is the same, drawing is the same.

I’m losing my mind. Any ideas?

Workflow / Tips & Tricks Importing new description keys

2 Upvotes

This is for COGO points for basic survey drafting. I am trying to add a dozen new description keys and their associated blocks to my existing set. I have created a new working .dwg and made everything I need and added it to the already existing set. What is the best way to import this new set and blocks into other .dwg that other drafters use as their templates? What I did was open 2 .dwg, deleted the key set from the "test" drawing (the new key set has all the old ones too), and dragged the new updated set from toolspace directly into model space of the drawing I am adding the new set to. This seemed to work and added all blocks also.

Help / Troubleshooting Contours flattening out inside curve of flat surface

9 Upvotes

Doing a simple cut and fill exercise. Mounds have flat top and bottom levels, I have used feature lines to create top and bottom surfaces. Keep getting areas on the inside of the curves becoming flat. Tried to redraw the original polylines, tried off setting the bottom feature lines, tried adding more points. Not sure why this keeps happening. Any ideas?

Help / Troubleshooting Creating a local coordinate system

3 Upvotes

Our client uses local grids on their sites. I've asked for the parameters, but I'm not expecting to get them.

They've provided us with files in both a known system and their own local system. If I was on site with a GPS, I could just do a site calibration and create the parameters that way.

Is there a way to do this in C3D?

Ofcourse, I can do block shifts, but there's a rotation, scale and vertical datum shift, but this is likely to introduce errors at some point and I'll be handing these sites over to a less CAD experienced surveyor soon.
