How to hide a raster segment

I have been trying to explain this to a technician who is not very informative, but as I like him, I write the procedure here and we systematize the free consultancies.

The case

You have a background image, but you want to hide part of it for printing and presentation purposes. Microstation V8.5 is available

The options

Before I talked about how to do something this with Descartes, but for the purpose of merging several rasters and saving them as new images. In this case, it is not exactly what is needed as it is for display purposes only, it is not intended to cut the images.

So the option is to do it using the raster clip.

The solution

In the Raster manager, select the images you want to hide and the "Edit / Clip"

Then a little window pops up asking:

... you're wanting to clip, you can tell me from that ???, then you should choose the cut method and mode.

1. By means of an element

You can have an object drawn, which is a closed figure such as a polygon. So we choose the Element option, and then Clip Boundary; this is the result.

Once you have chosen the type of object (method) that it hides, you define whether you want to hide the inside, or the border. For this are the two options:

  • Clip Mask, hide it inside
  • Clip Boundary, hide the outside

2. By means of a table

In this case, it is possible to make a box without having to have an object, to do this choose "Block" and mark the box with the mouse. Then a new click to see the result.

3. By means of a fence

If there is a fence, it can have “flood” properties and can be practical for complex figures or boundaries that are not a closed shape. First, the fence must be made, and so it can be chosen from the “Method” option.

The following image shows different clips made, the red one with the “Element” method, the crossed one with “Fence”, the others with “Block”. And everyone can live together, the image is the same.

This fence is very practical, because in the Microstation XM or V8i versions the fences can be saved as if they were models.

There is also the option "modify clip" that allows you to edit the vertices, as I have done with one of the boxes. To delete one of the clips, use "edit / unclip" and you can select individually or all the boundaries.


Step by step

Summary of the procedure for non-technological; in this case, there is an image downloaded from Google Earth, and you want to cut it with respect to an 1 map: 10,000

1. Call the raster

2. Touch it in the raster manager

3. Edit / clip

4. Select Method "Block"

5. Select Mode "Clip Boundary"

6. Make the box with the mouse: To activate the snap is pressed ctrl + shift

7. Click on the screen.

Because of the fact that this quadrant It is not exactly a rectangle, you can choose "edit / modify clip" and the ends are made to the corresponding corners, always with the snap activated by ctrl + shift

The cunt

Man, I hope that even a refreshment will fall when they come here ... because this is in the readme.
