Drawing markup that keeps every issue on the spot where it happened

How do you leave a note on a drawing?

Open the sheet and long-press the spot; a pin drops there. Saving it takes four short steps, labelled in the Turkish interface as "Tip" (type), "Açıklama" (description), "Medya" (media) and "Atama" (assignment). The note is stored with its position on the drawing, so nobody has to describe which bathroom on which floor.

1. Open the sheet from "Paftalar", for example "A-101 Zemin kat planı". You can search sheets by number or title and star the ones you use most.
2. Zoom in and long-press the spot, or tap the plus button and pick the location.
3. Type: task, defect, request for information, observation, safety or revision request.
4. Description: a short title such as "Banyo seramik derzi eksik" (bathroom tile grout missing), optional details and an optional trade.
5. Media: take a photo, pick one from the library, record a voice note or shoot a video. Media is optional.
6. Assignment: choose the assignee, due date and priority (low, normal, high, critical) and save.

The pin is stored on the device at once and synced when there is signal. Its number (#14) is assigned by the server, so two people working offline never get the same number; until then the list shows a dash.

Which file formats work, and how are sheets split?

Santix reads DWG, DXF and PDF. Each layout or PDF page becomes a sheet, with its number, title, kind (floor plan, ceiling plan, section, elevation) and level read from the title block where possible. Processing runs on Santix's own CAD server in Frankfurt, not in the Autodesk cloud. Sheets drawn side by side in model space, which is common in Turkish offices, are found from title blocks, frames and title-block strips.

You keep working while a file is processed; the sheets screen shows whether each job is queued or how far along it is, and a failed job states the reason and can be retried by the person who uploaded it. Suggested rooms go through approval; see room data sheets.

What is in the plan viewer?

The viewer is kept simple enough to use with one hand on site.

A pin's shape shows its status and its colour and symbol show its type, so status can be read without relying on colour.

Which pin type should you use?

Santix has six pin types. Picking the right one separates a safety risk from a design question at a glance, and the revision request type starts its own approval flow.

Each pin can also carry a trade (tiling, plumbing, painting), which is how you pull "all open items for the tiler" before a weekly meeting.

What does a pin hold?

Photos are re-saved with a 2048-pixel long side, which also strips embedded location data. Videos come from the camera only, because a library video keeps a GPS position that cannot be removed on the device. Santix never asks for location permission.

What happens to a pin after it is placed?

Every pin has a status and stays on the list until it is closed. The buttons are verbs: start, mark blocked, send for checking, approve, close, reopen.

1. The field engineer opens the pin and assigns it to the subcontractor.
2. The subcontractor starts it, or marks it blocked with the reason in a comment.
3. When finished, the subcontractor adds a photo and sends it for checking.
4. The field engineer or site manager inspects it on site, approves it or sends it back with a comment.
5. The approved item is closed; it can be reopened if needed.

Subcontractors can move their own work forward but cannot mark it done or closed, and the database enforces this too. A revision request pin can open a revision record that goes through the site manager to the architect; see revision tracking.

Example: one week of pins on Ataşehir Blok B

Using Santix's sample project "Ataşehir Blok B" (ATB-02); people and firms are examples.

1. Monday: the field engineer opens "#14 bathroom tile grout missing" in room Z-03 as a defect with two photos and assigns it to the plumbing subcontractor, due 6 November.
2. The same day, the kitchen counter height is missing from the drawing; "#15" is opened as a request for information and assigned to the architect.
3. Tuesday: a ceiling crack in the hall is recorded as an observation, with a voice note on what to watch.
4. Wednesday: the subcontractor finishes the grout and sends it for checking with a photo.
5. Thursday: the site manager approves it on site; the architect answers the counter question and the pin is closed.

Whatever is left under the overdue filter on Friday is the agenda for the weekly meeting.

How do you filter the list?

The list hides finished work by default. All, assigned to me and overdue chips show counts; status, type and trade filters combine; search accepts a word from the title or a pin number. Overdue items come first, then priority, then the nearest due date. On iPad the list is on the left and the selected item, its media and comments on the right.

Who sees what?

The full matrix is on the roles page; inviting people is covered under team and invites.

What happens to pins when a new version arrives?

Pins are tied to the sheet by drawing coordinates, so they appear at the same point on a new version. The version a pin was placed on is kept, and the small location preview in the pin shows it on that version. Versions are numbered R1, R2, R3; the version list shows upload date, which one is current and any warnings. In overlay mode, lines from the top version are drawn in the accent colour and lines common to both stay dark.

What does the viewer not do?

• It does not edit drawings; changes are made in the architect's CAD software and uploaded as a new version.
• Uploading needs a connection; downloaded sheets open offline (see the offline field app).
• Scanned PDFs have no drawing scale: pins work, but rooms and areas cannot be measured.
• Very large files may be refused, with a message asking for layouts as separate files. Objects LibreDWG cannot read are counted and shown as a warning; asking the architect for a DXF usually helps.
• External references are not resolved; the architect should bind xrefs before sending.

Why not paper prints and WhatsApp photos?

A pen mark stays on one print, and a photo in a group chat loses its location within days. In Santix the note, photo, assignee and due date sit in one record at a fixed point on the drawing, with the history of who did what. See Santix instead of Excel and WhatsApp and our room schedule guide.
