I'm writing a 2D custom marker that shows the distances from the insertion point to the origin in plan.
Not really complicated, it basically uses SYMB_POS_X and SYMB_POS_Y to print the distances in plan.
It also uses GLOB_SCALE to convert elements (a few lines) from model to paper size.
Everything should be paper size in this object, and it is, except from the text position and its distance from the insertion point.
The user wants to change the text position (and the corresponding line that links the text with the insertion point), ie., they want to edit 'text_location_X' and 'text_location_Y' parameters.
I created editable hotspots so these parameters can be changed in plan view. For this to work properly, AFAIK, it has to be edited in model size.
So, I created two more parameters – 'text_location_XM' and 'text_location_YM' – that are the model sizes versions of text locations These parameters will be kept hidden in the dialog box of the object.
I have this in my Master Script:
IF (GLOB_MODPAR_NAME = "text_location_X") OR (GLOB_MODPAR_NAME = "text_location_Y") THEN
text_location_XM = text_location_X*GLOB_SCALE/1000
text_location_YM = text_location_Y*GLOB_SCALE/1000
ENDIF
IF (GLOB_MODPAR_NAME = "text_location_XM") OR (GLOB_MODPAR_NAME = "text_location_YM") THEN
text_location_X = text_location_XM*1000/GLOB_SCALE
text_location_Y = text_location_YM*1000/GLOB_SCALE
ENDIF
And this in my Parameter Script:
IF (GLOB_MODPAR_NAME = "text_location_X") OR (GLOB_MODPAR_NAME = "text_location_Y") THEN
text_location_XM = text_location_X*GLOB_SCALE/1000
text_location_YM = text_location_Y*GLOB_SCALE/1000
PARAMETERS text_location_XM = text_location_XM, text_location_YM = text_location_YM
ENDIF
IF (GLOB_MODPAR_NAME = "text_location_XM") OR (GLOB_MODPAR_NAME = "text_location_YM") THEN
text_location_X = text_location_XM*1000/GLOB_SCALE
text_location_Y = text_location_YM*1000/GLOB_SCALE
PARAMETERS text_location_X = text_location_X, text_location_Y = text_location_Y
ENDIF
Almost everything is working as expected. When changing the scale, all elements change accordingly, keeping their paper size.
Except form the text location and its corresponding connecting lines: when user changes plan scale, the scripts are keeping the model size parameters – 'text_location_XM' and 'text_location_YM' –, and recalculating the paper size parameters – 'text_location_X' and 'text_location_Y'.
I need the opposite behavior: the paper sizes should remain unchanged, as it happens to all other elements, and model sizes are recalculated.
If I didn't need these editable hotspots, I wouldn't need the model size parameters, and everything would behave as expected. But I could not find any proper way to edit the text location without having to resort to these extra parameters.
I am aware of the 'j11' attribute. From the GDL Reference Guide AC27 (pg. 203):
"attribute = 128*j8 + 256*j9 + 512*j10 + 1024*j11, where each j can be 0 or 1.
j8: hide hotspot (meaningful for types: 1,2,4,5),
j9: editable base hotspot (for types: 1,4),
j10: reverse the angle in 2D (for type 6),
j11: the value of paramReference is used as meters in paper space, the editable hotspot's distance from the base hotspot is scaled to view scale (for type 1)."
I thought that adding '1024' to the base hotspot (type 1) flag would allow in some way to convert the value from paper space to model space, eliminating the need to create additional parameters.
But I couldn't figure it out. Tried almost every possible combination of multiplying/dividing by 1000 and GLOB_SCALE, but nothing put the hotspot in the correct position and doing the correct stretchings.
Any advice?
Maybe GLOB_FEEDBACK_MODE would help?
Please help.
