But these objects must be a polygonal, because in the map scale they can (and must) shown whith whole geometry (size).

You can do that with points type objects and using blocks as the symbols. (once you learn the software. :smileyhappy: )

Murph, I don't understand you. Can you hel p me? How can I represent a polygonal object with points? If my object must be drawn with real sizes as a polygon, how can I represent it by point blocks?

Can you post a screen shot of what you want, more than just the towers but how you want them to show with the rest of the features in the map.

I created a sample dwg of how to do it yesterday however when I did a zoom and regen I got the nice feature from AutoCAD to kick in called fatal error and lost it all before I could save it. I'll try again tonight when I get home.

Did you try to creat poligonal feature object?

No I used point type features. See if you can open my sample attached.

Murph, thank you very much to try help me....!  For the point objects it is a very good method.

But in  topological requirerment of our project shown that an objects which sizes an shapes can be shown in the map scale must be drawn by polygonal feature. That is why I have find a way how I can represent, too. I drawed a polygonal feature. For the represent, I created a block like shape "X" and used it instead of Fill in Style Manager. But now I can't associat the size or scale of block with the feature using Expression. Because,  shapes and sizes of objects are differend.  Can you know about solving this problem.

And for all I am very much obliged to you and to other colleagues in this forum!

I still don't follow entirely your line of thinking.  I think you are making this to hard on yourself.  Scale is somewhat irrelevant when you draw, remember it is 1:1 like the real world.  Just draw everything.  Scale is relevant when you want to show the details relative to need.  Dots and lines between them can show the power line at 1:1,000,000 just fine if you want to see where it goes across the country but 1:10 may be necessary to see the details of where the engineer locates a tower base.  Scale is relative to the audience. 

 

Open Murph's drawing.  study what happens when you zoom in and out and watch the scale you are viewing at.  At any scale if you measure the length or width of a tower its is always the real world distance.  ie at a scale 1:100 or 1:555 or 1:1368.345 the tower always measures 30 meters or 50 meters which is its actual size.  What you see is in proportion to the scale you are viewing at.  1:100 easy to see the tower details, 1:1000 harder to see the tower details but easy to see the line span between 5 towers, etc.

 

You use styles to control the appearance to the point object rleative to what you want to show the audience.

 

Next look at the style he applied to the various towers he used.  The style is set to size context = map. units to meters and the width and height to the dimensions of the tower base and locked.  These settings cause the block to be shown on the screen in proportion to the scale of the view. ie it changes size in the view as scale changes but hold its dimensions.

 

Next look at the data table for the towers.  it has the model of tower, rotation, x,y location etc. Useful when you go out to the site and build towers.  at scale of 1:1200000 I can't see the picture of the tower details, but the data tells me what I need to know.

 

Back to styles.  you can change the appearance of the tower at different map scale with the ranges.  ie at a scale of 1:10000 to infnity the tower is a dot, at  1:10000 to 1:1000 it is the tower shaped block, at 1:100 to 1:10 your could change to a different block and show the individual tower structure peices, and at 1:10 show the nuts and bolts holding the whole thing together with a different block.  Just remember to draw the blocks 1:1 if you want the blocks to represent real world dimensions. 

 

This will hold true wherever you show the map to an audience.  on the screen in the office or out on the site, or when you print it on paper.
