About this app

PreCAD is a 2D CAD application.
You can use many drawing tools without any restrictions.

PreCAD saves files in its own format called "pcad" format, but it supports reading DXF, JWC, JWW (jw_cad) files and writing DXF, JWW files (but there are any unsupported elements, functions, and so on).
Although It is experimental, you can read PDF, HPGL, SVG and save PDF, PNG, HPGL, SVG.

You can use the "jws" format of jw_cad as the parts.

In addition to layers, there is a function called "sheet". You can set the scale of "Sheet". By using multiple "sheets", you can mix multiple scales in one drawing.
Also, you can create multiple pages.

The app cannot import any CAD file into an existing drawing except through PAGES. I always end up copying the CAD from the imported page to the current page I'm working on. It has OPEN (which opens a new file) and ADD PAGE FROM FILE (which imports a file but into another page). I want it to also be able to import to the current page, sheet and layer (or to preserve original layers) I'm working on or even the option to select target custom page, sheet and layer.

Love the app but needs to have an option to completely remove the ads. Please add a one off payment option to remove ads.

This is exactly what I needed. A simple pocket 2D cad drawing app for my phone to help with small projects plans. A little clunky at first, but once you find where everything is, it's pretty powerful. You can find the manual in Japanese in the "About this app" section in the app, which most phones can quickly translate for you. Minimal ads can be turned off by watching a minute long video ad. Bravo for a simple, useful app.
