Custom Section marker creation

Ahmed_K — Thu, 21 Nov 2024 18:12:15 GMT

Hi,

i created a new object from scratsh :

from the file menu command, i selected create new object,

then i selected a subtype : section marker,

in " 2D symbol" window, i draw the marker symbol using lines and hatches,

I have 2 questions :

1 - when i apply the marker to a section , it's stretched, and non responsible for size parameter, how to correct that ?

2 - how to add text to show the section name.

no need for dynamic hotspots, or any parametric stuff, a simple marker for daily work, nothing special.

Thanks.

stretched marker

how it should look like:

Hi @Ahmed_K

Draw the symbol inside a boundary square defined just by hotspots at the corners (see the picture below). That is to mantain the proportion. Draw the symbol with the dimensions you need for printing (e.g. if you are in 1:100 scale and you want it to be 1 cm x 1 cm draw it as 1 m x 1 m)

Select the symbol and the hotspots.

Go to menu File> Libraries and Objects> Save selection as object...> Object...

Clic on Select Subtype... and select Documentation Element> Drawing Symbol> Marker> Section-Elevation Marker> Section Marker

Check Use as subtype and Placeable options ON.

Clic on 2D script button.

mul2 shows boundary square dimensions (A x B).

Change add2 coordinates so square moves from the lower left corner to the middle top point of the top (-A/2 x -B).

(Optionally you can delete those parameters for pens you don't need at Parameters button.)

Now you can choose your new section marker from the section marker tool.

Regards.

Hi Ahmed,

Building on Ricardo's solution:

place a text next to the drawing. Set up its text style, anchor, etc. as needed, the actual text can be just some dummy value.
save as object
when you change the subtype, some parameters will be added to the parameter list: AC_MarkerText_1 is the ID, AC_MarkerText_2 is the name of the section. These parameters will be set by AC.
replace the dummy text string in 2D script (should be before an endparagraph statement) to AC_MarkerText_1

Is it possible to have different symbols on section line ends?

Without going the 3rd party route, you could use a Linked Marker to show the second marker head.
