When downloading a WMS image it asks me to specify the insertion parameters manually, what can I do?

If it shows you this message, it is because you have recently updated to version 8.5, where changes have been made in the installation of the files related to the Insert WMS command, and due to permission issues, not on all computers the installer can delete files from certain directories, to fix it in case you have AUTOCAD: "C:\Program Files\Autodesk\AutoCAD X", for ZWCAD: "C:\Program Files\ZWSOFT\ZWCAD X", for BRICSCAD\Program Files\Bricsys\BricsCAD VX en_US" where X is the version of the CAD, and in this directory you must find the file WMSMDT8.dll and delete it.

What is the command georeference images?

Elena Ruiz — Fri, 11 Jun 2021 09:19:00 +0000

It allows assigning or modifying the georeference of an orthophoto, using at least two pairs of points that relate marks in the image with points in the drawing, using a Helmert transformation or an Affine transformation from 3 pairs of points. With this command, the image is not modified, only its georeference.

What is the difference between WMS and WMTS services?

Elena Ruiz — Fri, 11 Jun 2021 09:18:15 +0000

Both services allow you to download orthophotos from different servers, using the same MDT command, but the main difference is in the resolution of the image obtained. WMS services usually have low resolution and only depend on the zoom we make in the drawing, and in the case of WMTS services you can choose the resolution factor, by default it is the one given by the zoom of the drawing, but it can be increased in several units depending on the server, and this will also increase the resolution, the size of the final image and the download time.

Although they share the extension BigTiff and Tiff are different formats. AutoCAD does not allow you to work with this format, so MDT offers the possibility of converting a BigTiff image to Tiff and scaling it in the chosen factor to work with greater agility.

The Route by Road command within the Maps / Render menu allows you to navigate on a realistic representation of the road. For this, the segment that contains all the analytical information, and the height and displacement of the observer with respect to the alignment must be indicated.

If the current surface is also specified, the realistic representation of the road integrated into the terrain will be shown in the image, with the default textures or with the orthophoto if available.
